VRAY Animation - Flickering Textures - GI Disabled
show user profile  adammichell
Hi all

I mainly work in print, but we're working on a few simple product animations.

The product has a material feature - it's a chameleon paint with flakes.

Even if the camera is panning quite slowly, there are so many of these flakes that it just produces the ever so common flickering effect. To speed things up and make things easier I've just disabled GI.

The scene is rendering extremely nicely, no noise in the reflections, lighting etc..(thanks Grant Warwick).

As I'm not experienced to animation I'm wondering if there's a fix for when rendering out complex and detailed texture maps / procedurals.

Thanks in advance

Adam

As long as you use the correct and perscribed animation technique to suit the animation (ie, camera or object animation) and follow the directions to the ticket, you'll get no flickering. Animation in vray does require certain render methods to follow.

Have you tried a soft AA filter?

Ha thanks for the replies, but the flickering has nothing to do with GI so all the above won't help unfortunately. The GI is disabled (systematically running through what is effecting the flickering).

For anyone who is interested - I've done some more research into the matter it appears it is more to do with the Moire Effect and Anti aliasing.

I'm going to run some tests and I'll post them up.

Good thanks Adam. I'm having issues with something similar at the moment so let me know how you get on. I'm also thinking you might want to experiment with, the bitmap blur values. Us stills guys tend to crank those values right down but that might not be ideal for animation.

Good luck!

Just a random thought - could it be that you've got doubled-up geometry, and the two surfaces are fighting for visibility?
