  1. Facet SOP ignores group selection

    Houdini7 posted a topic in Modeling

    Hi, i wanted to use the Facet SOP on a certain selection of points. The node network looks like this: The group parameters are as follows and select four points. The Facet SOP parameter are as follows: Every option I select in the Facet SOP (e.g. Make Planar) effects all points and not only the selected points. Has anyone an idea why ? Thanks in advance

  2. Faceted displacement

    guache posted a topic in Lighting & Rendering

    I'm getting a faceted appearance using a disp map, corresponding to the pixels in the disp map. Any way to smooth this out *without* increasing map resolution, increasing shading quality etc? Do I need to create vertex normals from the displaced geometry normals somehow? The displacement map is a float exr image, so color depth is not a problem. The vex code doing the displacement is as follows: vector mapclr=0; float mult=1.0; mapclr=texture(map,s,t); P+=mult*mapclr.r*normalize(N); N = computenormal(P);
