File size bloat from texture mappings

My file size has suddenly increased 10x, and according to Audit3dmFile, it’s due to my texture mappings: “102 texture mappings with 102 plug-in data items, 971281187 bytes (offset 154947 to 971436134)”

I’m using VRay to render, but I can’t figure out how to diagnose/manage this excessive texture mapping bloat. I deleted all of the VRay materials, used ‘Purge’, and switched to Rhino renderer, all to no avail.

Hello - if you really want to clear the decks, use-SaveAs with SavePlugInData=No. But this is a nuclear option, we should try to sort out what is really going on - have you asked Vray about this?
