I had a few assets and stuff used in my mods for LoG1 and been using some of those for a new mod in LoG2.
Only problem is while the models seem to work just fine the way light is cast on them can be rather buggy, with only parts being highlighted or they actually getting darker in the light to almost completely black.
Since I didn't make these myself I suppose there is little I can do from my end unless there is some sort of trick to fixing these myself.
A lot of the assets coming from the Dungeon Master and Mine tileset available for LoG1.
