Tree/Detail Normal Maps Aren't Rendered

Hello. I have a simple issue. I’ve been placing my details and trees on the terrain with the terrain painter tool. I realized that even though I have the normal map enabled tree shader and diffuse specular on the details, the normal aren’t rendering and it’s just a flat color texture. Any help is greatly appreciated. Thanks.

Bump Again. I still haven’t solved the issue

Are you sure that your “Tree/Detail Normal Maped” shader is relay used?
Are this trees maybe just billboards? billboards Trees are using a different shader.
