Dancing textures?

Increase your MIP scale and/or blurring and possibly consider raising your AA settings, and also playing around with the tolerance in the AA settings (also consider trying to use SAT instead of MIP if you ahve the memory), turn off GI and check that it's not a GI problem rather than a texture crawl problem, make sure that the texture itself on the material has MIP or SAT used, and doesn't have too low settings.

Thanks for the post Anders. Some specific questions. You say to raise or play with some of the settings. What are examples of those numbers for those settings? Specifically, the AA tolerance? What would be considered too low of a setting for MIP or SAT? How much memory would be considered enough for SAT? Currently running on an 8 core mac with 4 gigs of ram. Thanks again!

Unfortuantely it's a matter of palying, different settings are appropriate for different textures. It's hard to know though whether youre' talking about texture crawl, where it looks like moire patterns and effects, bad aliasing on the texture, of if youre' talking aobut GI flickering, in which case it's down to the GI settings themselves, you need to use the appropriate type (typically for things moving object animation, and with pretty high sample settings), it's a process of elimination and then careful tweaking to get the best rendertimes but with the best quality.

Ok. Hopefully I can find some time to do some tests before I need to do the final render. But we'll see. I think it actually might be GI issue based on your comments thus far. Does the GI or any of the other settings change the final render or affect it depending on the resolution? Just wondering because I might have time to do tests at 1/4 res if the results will still be the same at 100%. Thanks again.

not to sure about displacemenst but i think bump maps contribute a lot to texture crawling not sure if baking the texture with the bump can br done, if so this would help, maybe the same for displacement

I think I boiled it down to being an issue with my GI settings, and potentially upping my AA settings...I don't remember, once I started testing things, it was hard to keep track of all the changes. There were a few problem items in the scene that didn't need to be seen by GI, so I just put a composite tag on those and told it not to be seen by GI and problem fixed!
