I'm trying to render to a texture as test, I will use render to texture for some other stuff later.
To do this, I've applied a material based on a RenderTexture to a plane(TV) which is captured by the main camera (TV Camera). So, this plane is influenced by a material where the render texture is attached.
The real scene is captured by another camera (Capture Camera) used as the source of the RenderTexture.
So this is the structure of the scene: http://i43.tinypic.com/2n0lzdj.png
Every frame the shader uses the RenderTexture to color a plane.
Nevertheless, I obtain this output in a test scene with 0.3 nearClip and 1000 as far clip in the camera: http://i41.tinypic.com/2yltphx.png
As you can see in the image, and more concretely in the sides of the picture, the black surface is affecting the whole scene and not only the plane that is the one which has the materials applied.
Any suggestion? Can it be because of not cleaning the depth buffer?
Thanks in advance.
