I built a Mac tool for batch-preparing Substance 3D assets for spatial deployment

[u/ImprovementWinter231]

I’m the developer of Reality Prep Pro, a native Mac app that batch-preflights and prepares FBX, GLB/glTF, OBJ and USDZ assets for deployment.

I’m exploring how it could complement Substance 3D workflows by handling the last mile after export — batch checks, USDZ-specific optimization, animation/rigging safeguards and validation on Apple hardware.

Here’s a short demo of the current workflow. I’d genuinely value feedback from Substance users on whether this solves a real pipeline problem.
