j00ey Posted January 20, 2014 Share Posted January 20, 2014 (edited) Hi I'm struggling a bit with an unforseen problem. I'm quite new to Houdini and have never made a wetmap before but I understand [or thought I did] the principles involved but now I'm trying to transfer a 'dopwet' attribute to a 'wet' attribute on points scattered on my geometry [specifically, this is my setup - ]. I thought I was going to hit a problem earlier on with the scatter SOP but it copes fine with the geometry moving but I can't figure out how to get a solver SOP to use moving input points. I'm transferring the dopwet attribute in a VOPSOP in my SOP solver and it's accumulating correctly but on static input geo. Can anyone give me some pointers? Thanks very much in advance..

j00ey Posted January 21, 2014 Author Share Posted January 21, 2014 Ok, I figured out a way of getting this to work. I'm attaching a file here in case it's of use to anyone else - or in case anyone has a better solution. wetmap_deformingGeo.hipnc Quote Link to comment Share on other sites More sharing options...
Skybar Posted January 21, 2014 Share Posted January 21, 2014 There is a free asset on orbolt that does this, have a look at that. Quote Link to comment Share on other sites More sharing options...

Follyx Posted February 10, 2014 Share Posted February 10, 2014 @amorales: well, the principles of a wetmaps are well explained but on things worse: in the projectfile as well in the Videosolution the wetmap is ealier present as the drop (or whatelse) is hitting the ground. There are few areas wich own a wetmap but never become wet before. Also tuning the bias wont help. I do the tut by myself in the moment and I start to despairt. Have anyone a solution for that? Thanks in advance. Quote Link to comment Share on other sites More sharing options...
