I'm trying to write my first blender script to import a BVH animation and copy the keyframes from the imported rig to an existing rig. It seems to me there are two ways to do this:
Operate on the data directly, by looping over bpy.data.objects[rig].animation_data.action.fcurves.keyframes and somehow copying them into the corresponding data structure on the existing rig
Simulate the way a user would do it by setting the context to a 3D view, importing the mesh, setting the context to the curves editor, selecting all, copying, switching back to 3D view, selecting the existing rig, switching back to curves again and pasting the data
Number 1 sounds like the right way to me, but looking at the API it seems that it's more geared towards number 2. Is that right? The Blender way of doing things would be to set the selection and use the copy/paste operators?
I'd like to know which is the idiomatic way of doing things in Blender.
When we export .fbx file from blender and import them in unity, we get the object without textures and materials. I figured out to get the texture by selecting the image in UV/Image editor sreen and save it as a copy in Image Option.
But I couldn't find any way to save as or copy materials (already attached with object in blender) so that I could attach material to model/game object manually in unity3D.
I have gone through many toturials like baking textures etc. but nothing was helpful. Please note that I do not have to apply Material to model in blender, instead I want the copy of material that are already attached with object, came with .blend file got from internet source.
Tutorial link and explanation will be appreciated.
Have a look at this link
There you get the Information, that only the diffuse color can be exported. Thats more than i expected. Why?
Blender-materials are different than textures. There is no Dataformat for Blender-materials as you have them with textures or objects.
Blender-materials are bound to the internal Data and an full-export seems really hard. Look at blenders Outliner panel and change the view from "All Scenes" to "Datablocks". There you can see how many aspects could be exported. All those would be needed for a full-import on a different program. That is much work, which has not been done so far (as i know).
What I am ultimately trying to do is to create a grid of images for print that are minor variations of the same thing (different text is all). Looking through online resources I was able to create a script that changes the text and exports all of the images necessary (several hundred). What I am trying to do now is to import all of these images into a new photoshop document and lay them all out in a grid and I can't seem to find any examples of this.
Can anyone point me in the right direction to place a file at a specific coordinate (I'm using CS5 and have the design suite so if there is a way in illustrator to do this quickly...)?
Also, I'm open to other ideas on how to do this (even other programs) easily. It's for labels so the positioning on the sheet has to be pretty precise...
The art layer object has a translate() method that takes delta x and y params. You'll need to open each image, copy it to the target document, get its current location (using artLayer.bounds) and do the math to find the deltas to position it where you want it. Your deltas can be in pixels so you'll get plenty of precision.
Check out your 'JavaScript Scripting Reference' pdf in your Adobe install directory for more details.
Ok I'm marking Anna's response as the answer because though I didn't fully test it, it seems like it should work and answers the original question with jsx. However I'm also leaving my final solution in case anyone else runs across this with the same issue and may prefer this method as well.
What I ended up doing instead is using InDesign. I figured out that it has a grid option that lets you import a number of files and place them all in an equal grid in a single command. This is almost exactly what I was looking for, except that it leaves a small border/margin in between the columns and grids and mine were designed to meet exactly.
I couldn't figure out how to make it not have the border (I have very little experience with InDesign, it may be possible). However I was able to select all my images and scale them uniformly to be the correct size, then I just selected each column and dragged it over to snap to the adjacent column and the same with rows...
I am creating an image map using ImageMapster from here.
I have created a photoshop image with several images that I have cut out from the original photographs. Each image is on a separate layer.
Now, I need to get the path coordinates of each object, and I don't want to hover over every corner and manually write down each coordinate.
Is there an automated way to get this path?
Maybe there is some application or web service whence I can send my image and get the path in return?
I have tried exporting each layer separately and then importing them into illustrator and vectorizing the shape (it keeps the shape in its original position), but I can't figure out how to get the coordinate path as text. I can export it to svg, but that isn't the same simple code needed for the css image map.
Ah! After googling image-map, much thanks to Sven for the idea (he got my +1), I found this thread here on Stack Overflow.
So here is my process.
Prepare the image in Photoshop with each object on a separate layer with a transparent background (this will make it easy for you when you do the tracing).
Save your photoshop file.
Open the Photoshop file in Illustrator using File...Open (works in CS4 and CS5) and make sure to allow the option to import Photoshop's layers as separate objects. After you open the file, make sure NOT to move any of the objects around - you need them to be in the exact same place as they were in the photoshop file so they can superimpose each other when rendered to the imagemap.
Use the Live Trace with custom settings. Use the black & white mode with the threshold all the up (255). This will produce a black silhouette of the shape. (You can also use "ignore white"). Push the Trace button. If you have many layers, you can save this new tracing pattern as a preset - I called mine, Silhouette. Now, I just click on a layer and choose Silhouette from the tracing buttons' dropdown menu.
Expand the shape and make sure it consists of only a single flat shape:
you can use the blob brush in illustrator to blacken over any unwanted white areas
no groups
no compound shapes (or it won't work) - which means you can't create cutouts.
You can tell the shapes are right when you click on them - you should be able to see the path itself with no "other" shapes involved (perhaps the blob brush additions) - just a single path. An easy method is this:
select the shape
ungroup if necessary
release compound path
unite (shape mode merges all shapes into one)
Don't crop your image - you want your shape to be in the same place in the image's area as in your original photoshop image.
Don't join all the shapes together, either.
The shapes should all be individual whole shapes, all in their original locations, each on a separate layer.
Now, open Illustrator's Attributes panel, and make sure to "show options".
Select your shape and in the "Attributes" panel, switch the "Image Map" combo box from None to Polygon. Make sure to add a url (it doesn't matter what you put; you can change it later - I just put "#" and the name of the shape so I can tell which one it belongs to in the image map code)
Do this for each of the objects.
Now, in the File menu, go to "Save for Web and Devices". Skip all the settings here and just push "Save".
In the "Save As" (the title of the window is "Save Optimized As") dialogue box, use "Save As type:" and select HTML Only(*.html) if you just want the code, or HTML and Images if you want the sillouhuette, too (they will appear in a folder called "images") - and note your save location.
Now go open that html file in notepad!
Voila! All the shapes will be rendered for you as a pre-made image-map - points path and even html code. Here is what it looks like when you open in notepad the html file you just created: For this demo, I chose a particularly complicated image - one which you would never want to estimate by hand, nor have to do twice!
Don't forget to place the actual image file somewhere in your site's images folder. You can save the psd file for later and add more "stuff" if you want, and repeat the process.
I was able to create the image map this way for my photoshop picture in just a brief couple of minutes. After you do it once, it gets easier for next time.
This has been bugging me for so long and I don't have Illustrator to be able to use the solution proposed by BGM, that I created my own Photoshop addon.
You can get it here: https://creative.adobe.com/addons/products/2389
It writes all your paths' points' coordinates to a text file.
Should work for CS6 and above.
The way I use it is I create a marquee, right click -> make work path, rename my path, [repeat], then just export coords via my addon.
If anyone's interested in the scripts behind it, you can have a look here: http://pastebin.com/8ugcAV3j
In case you make any improvements, please post them here so that other people may use them as well.
Hope this helps someone.
EDIT: added link to source script (was only in comments before)
I used this to find the co-ordinates of the outline of a shape to make image hotspots for links in dreamweaver. If you have something else in mind, then you'll have to ignore some of it. This works on a single layer so you may want to make a "flattened copy first", but I don't see why it wouldn't work on a multi layered image.
Use wand to highlight area you want. This will be different for different images.
Right click and hit Make Work Path. Use a suitable tollerance which is found by trial and error. I just use the most sensitive.
Do this for all areas in all of your images creating separate paths for each.
Click edit then export paths to illustrator and save file in sensible place.
Open the saved file in word. Ignore the bumf the the top and use replace to remove ALL LETTERS. Don’t worry about the paragraph characters.
Note that all of the work paths are exported in the same file separated by a blank line so must copied and pasted separately to be used for each hotspot.
After inserting your image. Start making a map in dreamweaver with a couple of co-ordinates then simply replace these in the with information from the illustrator file for each of the map areas to be produced.
I add my updated answer I had to find since adobe has eliminated HTML output in many instances, I work mostly with photoshop (CS4) and this is a perfect solution:
1) download following file: https://github.com/andyhawkes/ps-paths-to-imagemap
2) open your image in photoshop and select the form with the magic wand
3) right click and select 'make work path' (the lesser the px, to more accurate)
4) go to File -> Scripts -> Browse ... and select the script from the first step
that's it !! this script will open your texteditor with the coordinates ...
Something like this may be useful;

Copy your image into position, then plot.
creating an image map is really simple.
First we need to look at the syntax of the code
Let's create a div.If we want to position it at the right side of our page,we can just begin by writing
<div align="right">
After that, we import the image that we are gonna map.
<img src="" alt="" width="" height="" usemap="#nameofmap" />
Now we have to define the map structure.First lets assume that you want a rectangular portion of an image to act like a hyperlink.
<map name="nameofmap">
<area href="wherever I wanna take that.com" alt="" title=""
shape=rect coords="A,B,C,D"></map>
Now we close the div.
</div>
If the shape is circular,we use the syntax
shape=circle coords="x,y,radius"
If shape is polygonal, we use
**shape=poly coords="a,b,c,d,e,f,gh"
Now comes the big part:How to find the image map coords.
Very simple.Go to
http://www.image-maps.com
Browse your image file,click "Start Mapping your image",then you proceed, and then on the next page,click "Import Old mapping Code" on the right.then you get the coords.
After that, you can use FIREBUG to change the coords according to your specifications,because image-maps only hyperlinks the whole image,so use firebug to change the coords and adjust according to your requirements.
Have fun.
Creating all the art for a large website often involves a couple dozen 50+mb photoshop files. Frequently, a given module may appear in more than one file.
Is there a way to reference an oft-used module from another file?
For instance -
"site-section-2.psd" references "common-module-h.psd", and "site-section-6.psd" also references "common-module-h.psd", so that any time updates are made to "common-module-h.psd", the updates appear in both files which reference it.
Possible?
(maybe with photoshop javascript?)
I've checked the JSX Photoshop Object Model, and you can access LayerComps, but there is no magic function to save from one file to another. Something like this could be written to disk, from file1.psd for example, then loaded into file2.psd.
It's a bit of a long shot and I don't know if it's worth the trouble.
For web prototyping I use Fireworks and and I'm pretty happy. You can easily create symbols (much like in Flash and Illustrator) and even save them to a Common Library, which means it will be easy peasy to keep your navigation items for example up to date, for all the files using it. You can even import PSD files into Fireworks, only not all the filters will be supported.
Don't know if you can keep most of the eye-candy in Photoshop and then assemble reamble versions with ease using Fireworks.
You can try converting all the layers into one smart object and then drag the smart object layer into the new .psd file.
Go to the Layers palette: Window > Layers(F7).
LMB SINGLE CLICK the top layer.
Scroll down Layer palette until you get to the bottom.
SHIFT + LMB SINGLE CLICK. At this point all the layers should be hilighted.
RMB SINGLE CLICK any of Layer "Titles".
You should see a menu pop up so use the mouse to scroll until you find "Convert to Smart Object". LMB SINGLE CLICK to convert all the layers into one smart object. The smart object can be edited by double clicking it in the Layers palette. You can also drag a smart object from one .PSD into another .PSD. I usually just open both .PSD files and drag the smart object form one Layers palette to the other Layers palette.
