Copy result of pass to another pass of the same shader
Just checking. Is this correct?
My shader has 3 passes:
First one is an horizontal gaussian blur:
The second a vertical gaussian blur applied to the previous (it is separable, so It's O(2n) instead of O(n^2).
After that, I apply a bloom, which is applying the blurred image to the original texture.
// Apply Gaussian blur RenderTexture temp1 = RenderTexture.GetTemporary(source.descriptor); Graphics.Blit(source, temp1, bloomMaterial, 0); RenderTexture temp2 = RenderTexture.GetTemporary(source.descriptor); Graphics.Blit(temp1, temp2, bloomMaterial, 1); // Apply bloom. The additional texture will be the result of those two steps bloomMaterial.SetTexture("_MainTex2", temp2); Graphics.Blit(source, destination, bloomMaterial, 2);
I'm having problems with DX11 and Unity is crashing. No idea if this is the reason.

OK. I didn't release the textures. I thought this was similar to other features of Unity.
RenderTexture.ReleaseTemporary(temp1); ...
Not is works.
