Houdini - FLIP: 'texturing' with @rest (test)
Hey, tried this once with the UVs but it seems to work even better when "Enable Rest Attribute" is toggled in the FLIP solver (Particles tab - Rest tab). The "rest" attrib can then be brought into the /mat context with a parm node (vector) and used instead of "uv" (or "u" and "v") to map patterns/color maps etc. onto the fluid (old news for some of course) - Just happy that it´s working to some extent :) enjoy...
P.s. Will have to redo the tut, I´m afraid - I did it manually whereas it´s much easier to just use the "Lava from Object" shelf tool. Won´t take forever though, no worry!
C U soon
Have Fun & Cheers!
