Shader based camera compositing.
I have 2 cameras, one at depth 0 (camA) and one at depth -1 (camB).
I want to render camB then render camA, but cut a piece out of camA's result using the a material in camA's view to, allowing camB to show through. The reason for this is that rendering a camera to a texture looks crummy up close, and I read a while back that this would be a simple solution. Alas I cannot find the post which explained this. If you are a bit of an expert in the shader department and have a more efficient way to do this feel free to give your input as well.
Note: Don't say Camera.RenderToTexture, or Camera.RenderToCubemap, if those worked I wouldn't have posted this.
Cubemap:To slow
Texture: Low Res
Out of curiosity, what did you set the resolution of the RenderTexture to when you tried that?
Tried up to 2048, unfortunately I intend to walk through the object, so it always becomes pixalated as I approach the geometry.
The best way to avoid confusion between camera views is using layers and culling mask.
you should
set to camA 'depth only' clear flags
don't draw anything in places where you want to see camB's image
All right, but is there a way I can force a material to draw through to the background, of camA?
camB draws first, so it's not "draw through camA", it's a "don't draw by camA" where you want to see camB's image. so just disable geometry/make it transparent and you'll see camB's image in that place
