Hi,

In houdini ‘procedural_forest’ video tutorials there is a method for painting per particle weight on a grid.

For the past 4 days i've tried everything to try to key frame the ‘pscale’ for all the particle weight i've painted at different times on a timeslider.
I haven't succeeded.

I've even imported the geometry info into geometry Chop as described in ‘point_dynamics_with_chops_part1.mov’ of the main sites tutorials. But all i could get is the tx,ty,tz values. I couldn't find a pscale channel, and am completely stuck.

Any help very much apprecated. I can, at the moment, paint the weight but cannot keyframe/save the weight(particle scale) for all the points at any point in time.

Thank you.
Mark
