Non-square camera render texture?

Unity Engine
1

So, I have a camera set up and rendering to a texture. I want to use that render texture in the new GUI system . However, if I set the viewport width/height to anything than 1/1, the render texture is either “clipped” or displays garbage. I tried setting it to 1/1.5 and 0.5/1 respectively to get a wide viewport.

Am I missing something here, is there another control for the camera view geometry? If not, how do I set the camera viewport to be wide, and pass that to a render texture and have it look as desired? I can’t seem to pull it off.

Thanks in advance! :slight_smile:

Well, OK. I did it, but I don’t get why it works the way it does. I set the width/height of the cam to 1/1, but set the rendertexture to 512x256. That gave me a wide texture which looks good.

However, I don’t understand the logic, and what if I want another relationship? Say, 1:1.85 or something?

Heeelp! :wink:

Then either create a non-power-of-two render texture with desired aspect (this can be done from code), or override Camera’s aspect property.

Sorry , should have asked if it could be done without code. In the future, maybe it could be a good idea to have the camera aspect exposed in the editor for situations like this?

Anyways, will code my solution. No worries. :slight_smile:
Thanks for the help!

Still works great 16 years later, thanks @Foxxis
