Twinkling

[dell]

Hi
Have a problem with paint effects brush.Im using Tomcats Cartoon shader (Maya 6.0.1).In the scene there is a river - paint effects brush (FlowingRapids) converted to poligons with texture . Everithing is OK, flow, waves, but on rendered image sequence the river have unwanted twinkling on surface.There is some way to avoid this?
Sorry for my english

Here is the link: Sequence AGUA

I hardly imagine how this brush look like, but this "twink" is because You have too small detail there. You can turn Oversample and OversamplePostFilter ON, and this would filter resulting image. Ot just render twice as large image and scale it down in post. Also in post You could add some blur or convolution to remove this.

Thanks for reply Oversample and OversamplePostFilter ar already turned on . But I didnt thought about the post.Well, Ill try it.
Tanks !

This brush moves a texture displacement function over stationary triangles( that displace with the texture ). Seen from above there should be no problem, as we do a bump map for details, but from profile the occlusion will jump as the triangle wiggle up and down. I'm guessing it will look better if you increase the subsegments and the tube sections so there are more triangles. Also try using the contrast sensitive production rendering( pfx oversample won't help if you've converted to poly).

Thanks Duncan.The problem was in subsegments/sections and also in fractal attributes.
