I am having a persistent issue when exporting glb and gltf models from blender (2.79) that have armature applied.
I am using this exporter.
Exporting the model with an armature NOT applied gives me the expected result (ie it appears as it does in Blender) but as soon as I apply an armature (before I have even added any animation) the model exports with all the shapes rotated.
There is at least some consistency to the problem in that it appears as though all the shapes are rotated through 90 degrees on the X axis (although some are positive and some are negative).
To compare I have exported a glb with no armature, a glb with armature, and an obj with armature just to check that there is no issue with my original file. (I have done the same with gltf just in case. You can see a screenshot of that comparison below brought into a-frame.
Here is a side view for ease of comparison. You can see how the individual shapes are flipped 90 on the x axis.
Here as well is a link to that aframe scene
And here is a link to a zip of the blender file
I have looked at many similar issues that suggest applying all rotation/scale etc. tidying up the model etc. I have done all that and tidied up my model as much as I know how. It seems as though the model and armature is ok as the obj export works fine.
I have seen similar questions such as this one but they are mostly to do with distortion of models once animated. I have worked backwards to understand the root of the problem and it does seem that simply applying the armature is what explodes the model in this way.
Am I doing something wrong? Is there an export setting I am missing?
Any help greatly appreciated as ever. And if any more info is needed, please let me know.

I have gltf model with rig and animation sequences (with .bin), exported from video game League of Legends. After mport into Blender, everything looks fine (almost, but that's not important for rig), but after exporting into other format (I export as .smd to use in Source Filmmaker, but also tried othe formats) and importing into Blender exported model armature mirrors along global Y. Here's how animation has to look
And here is what comes after export-import:
import mesh with armature, but without animation
and what comes with adding animation
(for this after previous screenshot I flipped mesh in edit mode along Y global).
I tried to mirror before/after export-import both armature and mesh. Nothing helped before. On last screenshot everything is flipped along global X. One day I fixed it, but her weapon (circle thing) is always behind her after export-import when it must be ahead of her.
I have a model that I am using as my gameworld in Godot and I am putting some textures on it in Blender. When exporting the model to .glb it seems to not be exporting some of the materials correctly.
The ones that are an image texture that I scaled using mapping.
It just skips the first two nodes. When I disconnect them the material looks like it does in Godot.
What it should look like (what it looks like in Blender):
What it looks like in Godot:
There also are some materials that use mix shaders to mix images together. These are also skipped and it just uses one of the two instead of mixing them.
What it should look like:
What it looks like in Godot:
The F is from an image with text that is overlayed ontop of the other image.
I am not really sure if these issues lie with the glTF format and certain shaders just don't work with it or that Godot doesn't want to import them.
I hope someone can help me with this.
Thanks in advance and have a nice day,

In general, arbitrary node graphs cannot be exported from Blender — see https://blender.stackexchange.com/a/57541/43930 for the long explanation of that. To ensure that the material will export correctly, you'll need to refer to the documentation for the Blender glTF exporter and configure your material accordingly. For more complicated effects, you can also bake Blender nodes down to simpler textures.
When I render my model these black lines/patterns appear all over it.
I tried recalculating normals, deleted doubles, and checked for extra faces, but everything seems alright.
Other models that I created from the same base model are ok, so I really don't know where the problem comes from. In the picture they also have th same material so it's not that either.
The two rendered models side by side:
Anyone have an idea of how I can fix this?

For some reason, you have double mirror modifier in second mesh, remove one of them
I am in the blender compositing panel and i was using cycles at the time and i found my self making blurs and glares for lights in my scene, however what if i wanted to make two differant emmision objects but have one with differant properties than the other, because i found that when you use compositing it effects the entire image in the mask. i have tried moving too differant layers... but nothing worked. i dont know but masks might work... i havnt tried masks yet.
if any of that made any sense, any opinions would be amazing
thanks -Adam
the most recent update for blender was used "2.78"
I'm completely new to ArcGIS and ArcMap, but someone suggested this program to me for a project I'm working on.
I would like to animate individual entities on a map, and was wondering if it is possible to do so in ArcMap. I asked this earlier here and a member directed me to a tutorial on animating in ArcGIS. The animation in the guide was over a map spread (ie. each pixel on the map displays, say, a different color to indicate population data in the area). However I realized that if I zoom in a lot, eventually the image will degenerate into pixels, which is why I need an actual object to mark a certain point. I checked some online tutorials and it seems like we can place markers on the map. Can someone tell me if it is possible to animate these markers (for example via a for-loop)? And if so, could you point me in a direction where to start?
Thanks in advance!
You can animate layers in ArcMap is the short answer. Its not as simple as using the timeline feature in Google Earth for example though. But then ArcMap is much more than just a visualization tool.
This help page on the ESRI web help looks like a good place to start.
I'm not 100% sure what you mean by the image degenerates into pixels. Are you saying that the markers were single points in the layer. Unlike Google Earth you are not confined to simply plotting points on the map. You can draw completely arbitrary shapes in ArcMap, which can be defined to cover actual areas of the map, so when you zoom-in the shape gets larger.
The way you need to load data into ArcMap to produce an animation isn't too simple. There might be other ways to do this, but the way I know of is to generate a NetCDF file. This file contains a 3D matrix of layer data, where each layer is separated through time. Because you generate a matrix, you are effectively placing a raster image over the map. Thus if you want to cover a large area, each matrix becomes large, and you multiply that by the number of time slices you wish to animate over.
Once you have a NetCDF file with your data in however, getting ArcMap to animate it and produce say a .avi file is pretty simple.
You could try just loading some of the example NetCDF datasets into ArcMap to see how/if they will work to get you started.
Hope that helps.
The upcoming v10 will have better time-aware capabilities, which will allow for animation.
