I have a problem when I use different texture formats but with same size in MRT.
I want use internal texture formats of GL_RGBA8 for the first render target and GL_INTENSITY32F_ARB for the second.
I know FBO spec. restricts textures with same internal formats, but I remember, DX allows this mismatch texture formats in MRT, which means that graphics hardware validates only the format size rather than the format itself.
If there is anyone who share this problem, could you point me a solution?
