My Material editor always crash when I try to save a new material I always have this kind of message. Must I save it in a specific folder or some things else like that ?


Can you click the "Details" button on the material editor error dialog and paste its contents here? It'd be helpful in debugging the issue.

First thing my normal map don't work I tried several DDS format but the render is always flat or with dxt5


The normal maps are simple DXT5 compressed textures.
I have no idea what is the cause of the blackness, failed texture binding or material compilation error maybe?
I could take a look at it if you could upload your non-working mod somewhere.
