[Sidefx-houdini-list] Anisotropic work around?

Hi Robert,

Thank you for your explanation. The problem for me however, is that UV texturing slides when using the option to subd in the renderer. If I instead render with a subd sop, the uv's behave correctly. Is there something I should tick to not get this behaviour?

When you use a subdivide SOP you are simply making more polygons. You 
are tesselating the model without achieving real subdivision surface 
rendering. The "Polygons as Subdivision Surfaces" render option actually 
treats the model like a subdivision surface and renders it with Mantra's 
micropolygon rendering (no triangles - no tesselation necessary). The 
goal of the subdivide SOP is to add detail to your model or to preview 
what the "Polygons as Subdivision Surfaces" render option does. In the 
second case you would set the display flag on the subdivide SOP but the 
render flag on the SOP just in front of the subdivide. (since the 
subdivide SOP isn't needed to get the right results.
