3__ Posted February 8, 2005 Share Posted February 8, 2005 hey is there a way to softpeak uvs? I'm trying to have a map scale undulate according to the objects's point colours... -cpb Quote Link to comment Share on other sites More sharing options...
George Posted February 8, 2005 Share Posted February 8, 2005 Hi cpb, In UVEdit there is a Soft Radius control... does that do what you want? Quote Link to comment Share on other sites More sharing options...
3__ Posted February 9, 2005 Author Share Posted February 9, 2005 yep , but that will only scale the entire selection about the world axis. I need to expand some clusters of texture verts (based on an attribute) while possibly contracting others. -cpb Quote Link to comment Share on other sites More sharing options...
sibarrick Posted February 9, 2005 Share Posted February 9, 2005 You could problem use point clouds to do this, you'd need to write a custom sop to do it though. Quote Link to comment Share on other sites More sharing options...
thekenny Posted February 9, 2005 Share Posted February 9, 2005 Um, I just made a quick crude way to do this.... You could just paint an attribute on the surface and use a pointSOP to composite in the attribute on the $MAPU or $MAPV. I painted an attribute, made a VEXsop to composite on to the surface over time and then just used a pointSOP to get it in the UVs. So, if you have an attribute called fun $MAPU*$FUN+(1-$MAPU) You would have to make sure have a scalar to help roll off the effect, all possible in VEX, or your shader. But I keep reading your first post and I"m thinking it could be solved in your shader and still use your point colors as the trigger as long as you pass the value in some how. -k Quote Link to comment Share on other sites More sharing options...
3__ Posted February 10, 2005 Author Share Posted February 10, 2005 thanks thekenny. the point sop option doesn't really contract/expand the uvs as well as softpeak, but on detailed objects its way more practical. attached is a hipfile with examples of two different methods. -cpb undulate.zip Quote Link to comment Share on other sites More sharing options...
