I’m wondering if the filterMode variable on a render target is altered depending on if that mode is supported by the hardware. Some older Radeon cards, for instance, support float textures, but only support point filtering. It seems fairly logical if the filterMode is simply restricted to only using available blending, but I don’t have one of those cards on a test machine that I can try it on to see if that’s how Unity works :(. Some of the effects I’m doing just won’t look right without blending on a float render target, so that’s the only way I could tell in the existing system to get that info, maybe. So does this work, or is there another way I’m missing to check for the hardware capability?
Sorry, it’s not.
Blending? 
Hehe, yea, meant filtering.
So, guess there needs to be something added for this. Guess it’s taken for granted that support exists (TBH, I did until I ran into this problem with my renderer).
