View Full Version : animation, leather material fast (interpolate) question
hi, is it possible that a fast (interpolate) reflection using mr arch & design material, could cause a wavy undulation of reflections in an animation of a sofa/chair over the surface of the cushions?
also using GI and FG. i did render every 10 frames to collect the FG information into a file before rendering the 120 frame animation.
or could it be that i need to render every 5 frames to collect the FG info?
only the camera moves.

I would say its the fast interpolate. I had the same issure where the glossie reflections would dance as the camera went past. The surface was an alucobond (powdercoated) metal.

Yep best to avoid using interpolated reflections with animation.
thanks. ha, i'm really not that smart about MR yet, it was a lucky guess!

I had some duct work rendering in a scene. I also had the " wavey" looking geometry. It turned out that one of less
experianced co workers used the A&D pearl preset, and did not uncheck interpolation.
Avoid at all cost in animation.
ha! good job by the way of being gentle "less experienced" :)
it was actually kind of neat, the surface of one of the leather chairs had like this white blob moving eerily across it. like some type of plasma crawly thing.
perhaps it's worth a mental note for some psychedelic effects. i wonder if it could be "predictable"?
anyway, re-rendered without the interpolation and sure enough that was it. DOH forgot to remove it from the translucent curtains, but no time to re-render.
interested folk can see a low-res crappy rush job here: http://www.3ddigitaldesigns.com/gruesenSteven_demoReel_nov272007.mov
please forgive i'm learning and don't have time to re-render. someone wanted to see some stuff so i put this together between work and the holiday this last week. lots of mistakes and etc... the room with the curtains undulating is about 1/2 through the video.
