Below is the link to a file that i have downloaded from “houdini exchange”. on opening the scene every thing works as expected, except one thing. In the “merge_fluid_geometry_fluid” SOP there is particlefluidsurface node connected to dopinport1. looking at the dopimport1 in detail view i can see the velocity(v) and color(Cd) attributes been transfered from merge_particle_fluid node…. and the data updates as the time changes. same data is supposed to be transfered to particlefluidsurface node as it is connected to it and also ….as there is “v” and “Cd” entered in its attribute parameter.

Now…. on viewing the particlefluidsurface node in detail view. i can see the velocity “v” and color “Cd” attributes transfered on it. Till here its fine….. the only problem is that attribute “v” and “Cd” are initialized to 0,0,0 and 1,1,1…. and they do not update as time changes. so the color of fluid surface that is generated by particlefluidsurface node remains 1,1,1 (white)…… according to scene description it should be two different fluid coloured RED and GREEN …and as they merge the colors also blend.

hope you have understood the problem…and if someone has any idea why this is happening PLEASE HELP ME understand it.
