I am working on my architectural project, trying to use lightmap only with main building which is in the center of the map.
However, when I put check on lightmapped, geometry become black.
I dont feel it is problem with original geometry(fbx) because it looks okay whenever I reimport my texture to editor, it become black again when I refresh editor(browser).
the Model you have uploaded either does not have a UV1 channel unwrap which is required for Lightmaps to bake
or if the model does contain a UV1, just make sure you do not have âConvert to GLBâ on on the Model Import settings and re-Import the Mesh because UV1 does not work well with .GLB files unfortunately
Edit : You could also use the Auto-Unwrap, but only use it if you have already re-imported the model as a JSON instead off a GLB
Thank you, since my model have UV map, I tried json and now it says UV1 is available.
However, it is still becoming blackâŚ
Weird part is when I reimport my textures, it works fine with lightmap for a while until I refresh my browserâŚ
Thanks for your information.
My building become black only when lightmapped is checkedâŚ
I understood that fbx might doesnât work sometimes, I feel the link you showed me is mainly about animation import? In my case, somehow lightmap doesnt function correctly, and it looks totally okay whenever I reimport my lightmap textures, becoming black again when editor was refreshedâŚ
I think problem is might be something with the connection between material and texture?
Because when this problem happens, material preview lost lightmap texture??
