moustik Posted November 5, 2014 Share Posted November 5, 2014 Hello, I'm a new user of houdini software and I have to do a snow simulation for a school project. I have to export an alembic file of my simulation in order to give it to the render guy. So for a better result I used a volume and convertVolume node to keep the "snow fracturing" which is better than particle fluid surface which tries to join particle and don't look like snow but mud. But I don't know how have uv with this method. (I have another problem that is the particles continue to move very slowly after a while so the mesh continue to moving even if nothing happen) Have you any sugestions or others topics or tuto to help me. Thank you. ps: sorry for my english i 'm a french guy. Quote Link to comment Share on other sites More sharing options...
pbarua Posted November 5, 2014 Share Posted November 5, 2014 But I don't know how have uv with this method. You can't maintain uv because topology is changing per frame. If you want it for some reason then you can attibtransfer uv from your points to polygons (after volumeconvert). Quote Link to comment Share on other sites More sharing options...
pbarua Posted November 5, 2014 Share Posted November 5, 2014 (I have another problem that is the particles continue to move very slowly after a while so the mesh continue to moving even if nothing happen) Do you have drag????? Quote Link to comment Share on other sites More sharing options...
pbarua Posted November 5, 2014 Share Posted November 5, 2014 Use drag or v@v *= 0.95; v@w *= 0.95; Quote Link to comment Share on other sites More sharing options...
