I might want to render some stuff again. But I'm wondering if I could use CUDA on my laptop (9600m gt) to render faster then my PC's Quad core @ 3Ghz.
I will be using Max 2009 and vray. Thanks in advance.
there have been a number of hardware based rendering accelerators for 3D, and so far they have all failed - don't ask me why. CPU is just the way to go.
Looks like very bright hotspots to me (judging by the placement of the different "pixels" - doesn't appear to be random).
See if there is anything called clamp or clip in the renderer options or framebuffer perhaps - I don't know Blender, so can't point to the exact location. But it should be somewhere.. I think.
If I'm right, then whats happening is that the hotspots (reflections of the lightsource or whatever it is) are so bright that the intensity differences to the neighboring pixels are too great for the anti aliasing to kick in. So, what you need is to tell the renderer to clamp/clip the values so they fall within a lower dynamic range. That way they are much more likely to be be antialiased properly and look better.
Ps. not seeing them in lower quality only means that the renderer isn't aiming for as great precision, and can therefor miss the areas that has these spots. Try moving the cam to the side and see if the spots shifts places as well (like reflections would behave) - if yes, then that's defo your problem.
A teammate asked me to do this render in high-res, so I did. If anyone else needs, you can use it. The first one is raw, but the 2nd one is a bit edited.
Sorry for not putting in img tags, but it's the same render as I posted before, so there was no use.
