Im new in houdini, and i search a way to make the effect of a sphere touch example a planes and transfert is color… If i export it in alembic, the geo preserve this new attribute? Or they have a way for that? Thank you! :)! Quote Link to comment Share on other sites More sharing options...

Furox Posted May 16, 2019 Author Share Posted May 16, 2019 Hi Rudinie :)! Thank you for your fast reply! You are right! This a good options for me! :)! But my main problem was that color do not stay into the surface of the planar. It follows the geometry, but unfortunately, it doesn't not paint into this surface :/ I would especially be able to paint with water (like a wave painted the beach with color) :)!

Midasssilver Posted May 16, 2019 Share Posted May 16, 2019 You need to add a solver sop and aggregate color over time. Using an expression like this in an attribute wrangle inside the solver. Have the first input to the wrangle be input 1 and the second input be prev_frame. Then use this code: Cd2 = point(1, "Cd", @ptnum); @Cd += Cd2; @Cd = clamp(@Cd, 0, 1); Quote Link to comment Share on other sites More sharing options...
