I’ve built a fairly simple instance setup using an imported mesh object. Everything works as expected until I introduce a wireframeSOP inside the geo to be instanced. The piece fragments in many directions and the pieces spread more and less as I move the t[xyz] parameters. Again, everything comes out normal, with all the instanced geos appearing in the proper form and proportions, with all textures working fine, until the wireframe is added. I would use the wireframe parameter in the material, except it comes out in a weird pattern, unlike the results from the wireframeSOP. With the instancing turned off, and the wireframe on, it works fine as well.
