I am using Corona version: 11 (Hotfix 1) and 3ds Max 2024. I am using Connecter 7.0.
I mostly drag & drop assets from the Connecter App but I tried merging assets through File > Import > Merge and it does the same thing. IR stops running and needs to start again.
After doing a bit more searching I think it has to do with Corona Proxy. Corona Proxies don't seem to stop IR when merging but regular .max files do. All Cosmos assets are Corona Proxes afaik.
