Larian Studios Forums Divinity - Original Sin Divinity Original Sin - Mods [WIP Tutorial] Material Editing (Image heavy!)

Hi, I did a katana 3D model but every time I pass it to the divinity engine 2 all the colors and materials are lost I only get the model with the default material, so how can I use the original materials of the katana in the engine??? Sorry for the newb question and thanks in advance.
