Specular from nowhere when using baked directional specular lightmaps.

[syenet]

I need a little help on strange specular in lightmaps, my test scene is set up like this:

I disable all lights, and no skybox or any reflection probe, I still get the specular light, what is it?

Another problem is that when I’m baking lightmaps, specular of point lights are always baked into lightmaps and the visual result is not good:

Even with baked resolution of 40, this still looks terrible, so for things like glass, mirror or other shiny objects, I prefer to only baking diffuse of point lights into lightmaps. But I can not find a way to do so, the render mode option only works for realtime lights, so it’s useless to set it to Not Important when baking.

Anyone could share some experience handling this kind of issues? Thanks.

For me. It looks just simply clear your lightmap data and the lighting should gone.

Hi, thanks for your reply, but what do you mean by “should gone”? should I remove them? not using lightmaps?

Fully clear the lightmapping data and re-bake again.
