Yep, that must be it, i was thinking to solve this from wrong direction as how do i affect the next guy rather than should be infected, let me give that a spin

Hello,
I am trying to solve a problem, but kind of stuck

Basically I am trying to do a propagation, but only based on a vector available per point on the attribute itself, so if the underlying point says go right, spread should be only to the right, and next frame we query again, check the vector and only spread along that direction.

So I played around with points in a solver sop, pcopen check the nearest attribute on the surface @P+=v@dir; and points move as expected.

But how do I do that for an attribute on the geo itself. Well I mean not the attribute but the value of the next point that should inherit the value on the neighboring point based on the direction vector. Almost like a 2d gas solver I suppose. But the surface is not a plane, and UVs are not very straight forward to work on UV space on a grid.
Open to ideas, Thanks

works just fine, lol, I feel defeated
I guess then my next question would be why does it take so long to show up. and if there is a flag to make it show up faster.

Thanks man
