Hey this is probably something stupid on my end but i'm new to Blender, making some items for Worms and everything I import in is very glossy and shimmers.

I've tried a bunch of things with the materials/textures but nothing's worked (I followed the Steam Workshop preview to the T) so i'm hoping there's a guru out there that can clear things up and help me get items more matte when you import them over.

Thanks!
