yjcnbnbnb200 Posted September 4, 2013 Share Posted September 4, 2013 I have a basic flip simulation and use dop import to read in, then i have vdb and adb smooth, so the render is very quick, now i want to export the motion vector pass for this vdb mesh, but i do not know how to do, all the particle s have 'v' attribute, but vdb do not have, so the shader I use on normal mesh do not work with vdb. So anyone knows how to solve it? Quote Link to comment Share on other sites More sharing options...
Skybar Posted September 4, 2013 Share Posted September 4, 2013 (edited) If you set up a flip sim from the shelf, and then have a look at how it gets meshed - you can see that 'v' gets copied from the particles to the mesh with a Point Wrangle. You could try that. Edited September 4, 2013 by Skybar Quote Link to comment Share on other sites More sharing options...

Thanks for your reply, but what I care is, can the shape of node vdb the same as the shape 'after node convert vdb', so what houdini do is from render no different, just one is volume, another is mesh, is it correct? I just give the vector shader I used to the mesh after point wrangle? Quote Link to comment Share on other sites More sharing options...
