Hi... I have created a scene where ocean waves hit sand... Used the beach tank from Oceans tool shelf. In order to accomplish the wetmap on sand I have taken the following steps: 1) Cached out the fluid surface cache 2) Scattered points on the fluid surface and added @wetness = 1 attribute 3) Used group bounding box delete to only keep the points near the shore 4) Scattered points on the sand surface and added @wetness = 0 attribute, points inherit UVs from sand - note sand geo has UV textures applied on the diffuse and other channels. Y axis projection, scale = 15, 15, 15. Resolution 8K. 5) Created another geo and object merged from #2 and #4 6) In that geo created a solver that: - copies wetness attribute from previous frame of the sand-scattered points onto current frame - uses attribute transfer to transfer wetness from fluid particles 7) This works great... so I have points scattered on the fluid particles transfering wetness attribute to points scattered on the sand particles. But how do I convert that into an animated map that I can load onto the original sand object? How do I blend that map with existing textures? - I have tried to follow a tutorial where author created a vopcop2 generator in img context and created the flow in VOP as per attached file - But this is not really working well... (a) its very slow (b) I get a small something that doesn't seem to animate or read the exact details of the points. Is there a better way do do this? One that might actually work? Huge thanks.

Hey Houdini Users ! I am currently making a wetmap for my shot and I am having issue with the stepping when using the solver SOP. I tried increasing the substeps and also putting a Timeblend+Timeshift to interpolate between frames but neither of them seems to be working. If anyone know how to clear out this stepping and have a smooth trail for the wetmap please enlighten me Attached are the files, one is gif and other is mov. Wetmap_v001.mov

Hi there, Im stuck on this problem im facing. I have created a material which basically shows the wetmap (collision history) of my flip fluid colliding with my static object. The issue I face is how to export this diffuse material as an animated image sequence in the correct uv space and unwrap of the static object model. i want to use this in maya as a shader. If anyone has any suggestions i would be thankfull forever :). Cheers.
