Variation shader inadvertently affected by a field
-
I have a winding pathway (an editable cube with many polygons) with the variation shader set so each of its polygons have a different color. Along either side of this pathway, I'm growing cloned cubes by means of an animated linear field. The problem is that while the field animates (growing the cubes from scale -1 to 0), polygons in the pathway change colors as if its variation shader random seed has been keyframed, but it hasn't. Is there a way to prevent this?
thanks,
- Mike

Hi Mike,
Does the file show what you need, or at least duplicate your setup?
CV4_2023_drs_23_MGvs_01.c4dAll the best

Close Dr. Sassi, but not quite, and I appreciate your attempt! My winding colorful path is not part of the cloner. The cloner has one child (a cube), mode:Object, distribution: surface, and the surface object is a plane with some subdivision surfacing to make the plane look hilly. The clones begin to appear as a plain efffector's linear field sweeps over it, "growing" the cubes from a scale of -1 to 0. It seems like the variation shader in the winding path's material takes into account the sum total of all objects in the scene when it calculates the random seed. That's the only thing I can think of. I'm not keyframing anything int he variation shader itself, and the "flickering" of colors in the path only occur within the field's animation timespan.
