cherm Posted August 11, 2007 Share Posted August 11, 2007 Hi there, I am trying to create procedural textured shader in VOPs. Let's say I have my box and I want to texture top, sides and bottom primitives seperately, and I want to be able to control them procedurally. The thing is that I am not good at VOPs at all ; to be honest this is my first attempt. Can anybody give me a pointer where to start? all helps much appreciated. cheers pol Quote Link to comment Share on other sites More sharing options...

Just create a parameter vop and be sure the parameter name is the same name as the attribute you created. Another way is if you take that box and facet it to have unique points, run it through the connectivty and partition sops, re-consolidate the points (if you want) and then apply a seperate shader for each group created. That could get a little crazy if it's more than a box, but you can adapt the process to suit your needs. cheers _chip Quote Link to comment Share on other sites More sharing options...

The reason that I want it procedural is because I have my ground which will be dynamically broken in chunks like Miguel did in his Road Destruction. Anyways, thanks for your suggestion. I will try my best, but don't know if I can manage to do it correctly or not. fingers crossed.... . cheers Pol Quote Link to comment Share on other sites More sharing options...

In that case just use the extrude groups and apply a different shader to the top and sides. In the extrude sop there is a group tab where you can enable groups for the front, back, and side primitives. Quote Link to comment Share on other sites More sharing options...
