View Full Version : colliding geometry with paint fx

hya all
is there a way to collide geometry with paint effects?
have a field parented to the geometry that influences the paint effects maybe?
in any case, i can't seem to find a way to attach a field or geometry as deflectors to the strokes (as the strokes are not particles, of course)
tried converting them to springs, etc, still not working
i remember reading somewhere about paint effects being influenced by fields, so i guess it is possible.
has anyone tried this before?
a little help would be great
thnx

Hello,


You can convert PaintFX to Poly's. Maybe this will help.

well...aa, of course i can
but i was just asking for a solution directly with the paint fx curves
i was asking if u can collide objects or attach fields to a paint fx system (i have read about it, so i guess u can).
now, i didn;t say there aren't workarounds
like converting to polys and then making softbodys out of them and then have them affected by anything (yet this is not practical at all, since u end up with alot of polys and gets slow on the simulation side)
another way would be to have a custom lattice around the paint fx and make that a softbody and collide that with anything
yet another workaround would be to convert to polys, "skin" them up with bones, use hair curves as drivers for bones, and have the curves deflect objects or be influenced by any field...now this works...but takes A WHILE to set up

so my question was: can paintfx be influenced by fields of by colliding objects with it?

The way I do it is:

Draw your curve, make it dynamic under the hair menu. Then attach your paint FX to the dynamic curve. Your paintFX stroke will have the same responsiveness to fields and colliding objects as the hair system its attached to.

If your colliding geometry you may need to up the "collide over sample" setting.

thnx a bunch
PS. bashing my head....i should have thought of that :)

Note that you can also simply assign your brush to the generated hair system.. this is more efficient than going through the output curve. It is also better because the brush normal is aligned to the hair twist vector... otherwise the twist is poorly defined.
