blendingshadow Posted July 31, 2014 Share Posted July 31, 2014 Hello, I have a fluid source that bursts. The source has been converted into a vdb, reshaped and smoothed. I have animated erosion on the mesh but it still 'pops' off. How would you go about fading a vdb fluid mesh based on the age of the point? Would this be done in the shader somehow. Any help would be much appreciated. Ta Quote Link to comment Share on other sites More sharing options...
eetu Posted July 31, 2014 Share Posted July 31, 2014 (edited) Hi! At its simplest it can be quite easy. In the fluid mesh object's AttribTransfer SOP add age to the existing v in the list of attributes to be transferred from particles to mesh. After that remap age to Alpha in e.g. a VOP SOP. No need to touch the shader (because Alpha attribute support has been built in). edit: Oh, and remember to enable "Age Particles" in FLIP Solver -> Particle Motion -> Behavior ee_flip_age_fade.hip Edited July 31, 2014 by eetu Quote Link to comment Share on other sites More sharing options...
