I would like help figuring out how to force Blender to allow me to use OpenSubDiv using my Intel card on my computer. Blender has 2 major hardware limitations when it comes to the new OpenSubDiv support in 2.76. Here is a page that describes that: http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.76/OpenSubdiv#Hardware_Limitations . The problem isn’t that I have AMD hardware on my computer. Rather, the problem is that I have an Intel card on my computer. I can see that the solution is to set an environmental variable to OPENSUBDIV_ALLOW_INTEL . However, I do not know how to do this. Can someone point me in the right direction?
