3dbeing Posted January 21, 2012 Share Posted January 21, 2012 Sure I create Some Erosion ... But it's Not good. I don't know this correct or... < I don't know how to create particle. Anyone have other Idea? That's a nice model. When you say erosion, what do you mean? Do you want geo erosion or shader erosion? What are you trying to use the particles for?

Macha Posted January 27, 2012 Share Posted January 27, 2012 An idea: Turn your object into an sdf and shrink it. Emit particles from those erosion sites. SDF creation for complex shapes can be very difficult and resource intensive though. Another erosion technique could be to displace along normals, recalculate normals, displace again, etc. You can do that with a foreach node. With the sdf you get the advantage of getting a free collision geo, if that is important. Quote Link to comment Share on other sites More sharing options...
papicrunch Posted January 29, 2012 Share Posted January 29, 2012 you can also look to Varomix tutorial on cmivfx here for a more complexe erosion system. have fun, Thomas Quote Link to comment Share on other sites More sharing options...
