Camera projection bug ...

Hi there folks,

Long time lurker first time poster.

I have a question about the camera projection in octane and if it's working correctly ?

The example scene has a plane with some instanced spheres. Both the plane and the spheres have a square texture projected onto them via a square camera, essentially top down. The problem is that the render camera resolution settings seem to affect the texture projection. If I change the resolution on the render camera the result changes as per the pics. It seems that to get correct results you can only project with a camera that has the same aspect ratio as the render camera.

Yes, I can reproduce this problem here ... I will try to fix it, but currently the projection changes with the aspect ratio of the rendering camera if the camera projection is other camera. If all the cameras have the same aspect ratio all should work fine.

Thanks for report it.

Thanks Juanjo.
"If all the cameras have the same aspect ratio all should work fine" - that's the approach I'm taking now and changing the image projection size to match that of the camera. Thanks for taking a look at this.
