displacement problem

Recommended Posts

I'm having an issue with the rendering of some displacements... I want to only displace the sides of an extruded set of primitives... but the primitives fray from the rest of the object.

(The sides are grouped by a polyextrude node)


is there any way to fix this?

Cheers in advance :)

oh and attached is a hip :)

(if it's not there already... skip to frame 85 or so...)

It does this because your geometry is not fused, there's nothing to stop things from getting ripped apart.

Fusing the points might cause other problems, but you should try it anyway... It will probably prevent the sides from splitting, but I don't know what will happen at the shader boundary between the sides and top, my guess is it will split or streak badly.

I see what you are trying to do, will be cool if you manage to get it working. You will probably have to inset the top edge and manipulate the normals along the edges to point in the same direction as the side faces, so that the displacement happens in that direction.

and add the re-dice displacements rendering attribute if you get nasty artefacts.

hope this helps
