Cycles Render just renders a pitch black image - blender

I'm trying to make a very simple scene ( the one made on this tutorial : https://youtu.be/5tG2wSNCBmE ) and it just renders a pitch black image! I'm new to Blender, so if this is a really dumb, easily fixable issue, I'm sorry.
Here's the .blend file : https://www.dropbox.com/s/yzbyknj81q3a92z/House.blend?dl=0

In your render settings under Film you have changed the exposure to 0.0
Turn that back up to 1.0 for your render to work.

Render don't start in blender while using Cycles

I just appended two blender files to get my two models in one scene. when I hit Render Image. It doesn't start rendering although before appending the two files the render was working properly. I tried to render the default scene(Cube scene) in blender and it rendered. I guess the problem is not with my camera because I created a new camera and made it my active camera and still not working. all the objects appear in the viewport shading and none of them are hidden.
one more thing the GPU compute option is no longer active besides it was active before and worked with me.
I just figured out the problem. the sequencer in the output properties was checked on. to check it off go to Output Properties > Post Processing > Sequencer.
I'd just like to add my solution which bugged my mind an hour ago:
Blender has two options for rendering, which confused me at first, and might confuse others as well.
Render -> View Render will view the previous rendered image. However, if you've just opened Blender, then there's no previously rendered image of your viewport.
In order to render the viewport, you'll have to tap Render -> Render Image first. Then at a later stage you can do Render -> View Render to view that image.
I guess the same works for animations as well, first you'll need to do Render -> Render Animation to render your animation, then later do Render -> View Animation.
Encountered the same problem. Disabling the sequencer, as OP mentioned, didn't do anything. For me the problem was in the output path for animation; in Output Properties > Output.
My destination folder was moved (it was a very old project) and Blender seems to have no problem with rendering images to a folder that does not exist. However this is not the case with animation. I imagine that when rendering animation, blender uses the target folder to store rendered frames and when everything is rendered, takes the frames and makes the animation.
I do not have any insight into how blender works nor do I have experience with programming so take this as an uneducated guess.
;TLDR:
Check your destination folder, blender seems to be fine with rendering images to non existent folders. This is not the case with animations.

Render horizon silhouette using Metal in SceneKit

I'm working on simple side project and small part of it is rendering a terrain. I'm rendering the terrain using height map information. But here is my problem:
I would like to render just a silhouette/outline of the terrain/horizon. Here is screenshot from my app rendering height map:
And here is screenshot similar to desired result from peakfinder.org:
I would like to draw just lines representing silhouette of terrain with the rest transparent or solid colour. How can I solve it? Calculate local maximum somehow?
I created sample project here, in case you want to help me.
Thanks!

Render texture and normalized view rect in Unity

I'm using Unity 3D 3.5 pro.
I've got this scene with two cameras in it. One of them is looking at a plane that has a render texture on it. The other is recording the render texture. When the camera that's recording the render texture has a 1:1 normalized view and height rect, everything is fine. But when It's something different, some weird stuff happens -- the render texture's image becomes distorted. I've tried releasing and discarding the render texture's contents in an update function, but nothing changes! It's totally stopping the project I'm working on from being completed. I have pictures here to explain the situation in detail. The reason its a problem is because i need to be able to place non rectangular objects in front of the square and not have their scales appear to be distorted, due to the scale of the plane on which the render texture is being shown not being a square. What could I be doing wrong?
I also placed a similar question on unity answers, but received no usable help there. Here was the thread:
http://answers.unity3d.com/questions/389094/rendertexture-normalized-view-rect.html
I figured it out. I needed to mess with the offset and tiling of the rendertexture. Silly rabbit!
