We are working on an effect using Gustavo's Motion Tools kit. Getting stuck trying to pull the color from the point cloud and put it onto the islands. Anyone done this and have any tips? We are trying to get the color piped into a CAV map.

I think we got it working using self.color instead of using the CAV. I'll post again if a different approach worked in case anyone runs into this later.

Would this help?

Someone might need to bump it if I'm still landing in the Spam bin.

Hey Byron, nice to see MT still in use. If I understand you correctly this should be the answer:

It is a bit over complicated because, unlike weightmaps and contrary to its name, CAV contex is not the vertex. It is actually a sample you can get from self.NodeLocation. There is also a way to directly display the perpoint data via OpenGL (

Best regards, share your work whenever its ready, if possible.

Thanks Gustavo and Adam. Once we finish the spot I'll post a link to it. Ed Manning is here with me. Long hours and good times!
