This might seem like a stupid question (now that I'm typing it out I feel the answer is no.) Can you spawn an event based on render time events? Be it say from render time AO or a curvature map.

Use a Position Object operator and set the density to be controlled by texmap...drag in your map and it should work Smile

Gradient ascent/trace won't work with pure blacks/whites. It's basically forming a UV-space vector by examining color value differences in a small sampling of texture points. Imagine your bitmap used as a displacement map on a mesh...the gradient modes are basically trying to find the direction of a slope created by your bitmap. Pure black/white areas have no slope and thus won't return a meaningful vector.

I'll see if I can find a way to make them only flow on the areas I want tomorrow. So far this event has been pretty stable, no crashes yet.
