Hey All - I have modeled this three times. Blender, then blender and Zbrush, then just Zbrush. Every version has had unsupported minima, but in the supports themselves.
The red minima can be seen through the models in the screenshot.
Additionally, all versions of thie model (from the various modeling packages) have occasionally caused Preform to crash. I have no idea what the reason. All drivers and software are up to date, and the triangle count on the models is very low.
Any thoughts? Thanks.
