    Hi, Maybe you stumbled upon my video on facebook Houdini Artists. Still, I cross-post because I'd like to get your critique - which is something hard to get on facebook! I'm working on a snow-covered terrain shading and rendering in Mantra. The geometry was sculpted by another artist but I added some details with displacements. I want to achieve a look of smooth, almost untouched snow covering rocky highlands (not Arctic glaciers). What can I improve? ~20 min per frame at 720p on Intel i7-3770 Still frame: For comparison, original terrain model (plain diffuse material):

    You can group via spherical bounding and grow/animate the radius of the sphere or box over time. Or create multiple bounding objects and animate/position over time. If you have not watched Konstantin's video on how to model a shampoo tube I recommend it. There are a lot of selection tricks demonstrated. Thanks again for that tutorial Konstantin!

    https://vimeo.com/84576619 a houdini digital asset that consist of two part. Deformer : - Deform source by pushing points. - Customize the shape of edges. - Rest force for pushing back points. - Export deformation as displacement map. Painter : - Paint on source. - Ability to erase or growth painted area. - Export paint as color map.

    That microsolver is used in the old SPH fluids to maintain a list of neighbor particles within a search radius. These days you're better off just using pcfind and storing the results in array attributes. So using a POP or Geometry Wrangle: // next two variables could be parameters int maxn = 100; float scale = 2.5; float searchrad = f@pscale * scale; // find nearby particles int n[] = pcfind(0, "P", @P, searchrad, maxn + 1); // remove this particle from list removevalue(neighbors, @ptnum); i[]@neighbors = n; On the Inputs tab set Input 1 to Myself or Myself (no reads of Outputs), the latter being faster. You can then loop through that array to do various neighbor-lookup type things. The POP Grains solver does lots of this if you want to look inside.
