Found the issue... it can only function if you run in directX 12 with the AgamaMaterials-dx.bat file
now version 0.18 broke DX 12 and normal mode breaks the models(sticking with version 0.17)
Hi! Could you check and send me logs from "C:\Users\<user>\AppData\Local\AgamaMaterials\" on company@agamamaterials.com?
DX 12 fixed in 0.18.1. But anyway, could you send us an example of the broken model?
