Hii devs,
I am trying to bake GI for my scene which consists of 4 point lights, mode set to mixed, Render mode set to important, shadow type set to Hard Shadows.
The model’s mesh renderer settings are set properly to contribute GI and I’ve also ticked the generate lightmap UVs in the model importer.
I am baking using the Shadowmask Mode.
When I bake lighting, there are no baked shadows when I am in Shadowmask Mode, and the quality of the scene lighting is affected badly after bake.
UPDATE*
I tried changing the point lights with spot, and directional lights, but still, there are no baked shadows at all. All other scenes in my project have baked shadows, only this scene has some bug.
Also tried replacing the lighting settings asset with a new one… Still, the problem persists.
Baked lighting looks different than the realtime pic. It feels like the light is coming from a different place.
Make sure this isn’t a UV issue, and try to test with 1 light at the top. And check on all meshes that they receive/contribute GI and are static
Yeah I know it looks different, but all the scenes that have baked lighting in my project have good quality baked shadows. Only this is the scene where the shadows disappear after bake.
I tried using one light, and all my meshes that contribute GI are marked static.
Judging from the Baked Lightmap view, baked indirect shadows are indeed there. However, I can see some issues with your current scene setup:
Your lightmap UVs contain a lot of distortion. You can see how stretched some of the texels are. Author lightmap UVs yourself, or have Unity generate them for you in the mesh importer settings
Some of the meshes have very low lightmap resolution. Again, just look at the texels. Baked shadows will have almost no definition on such meshes
Why are you mixed lights with the Subtractive lighting mode? Only directional lights will provide realtime specular response. Other punctual lights (spot, point, etc.) will be treated as baked lights. If you want to take full advantage from mixed lights, please use either Baked Indirect or Shadowmask lighting mode. You can read more about it here: Unity - Manual: Lighting Mode
I would strongly recommend reading the manual, and watching some videos on the subject of lightmapping. Here’s a good video to start with:
Yeah, I have enabled Generate Lightmap UVs option in mesh importer settings. Also, I’ve tried increasing the ‘scale in lightmap’ and baking the scene in Shadowmask mode.
Still I am unable to see baked shadows…
UPDATE*
I tried baking my scene at 200 Texels per unit and all other highest lightmap settings. Now I got to see some shadows but they are way too stretched and blurry. There seems a problem with the model or uvs. Here’s the screenshot of how the shadows are looking:
Each square you see in the lightmap view represents exactly one texel in the resulting lightmap:
The entire texel will either be in shadow or not, it cannot represent details smaller than itself. So you need to increase the resolution and preferably also reduce the distortion in the loghtmap UVs.
Bro the mesh renderer is already set to the highest scale in lightmap and I am baking such a small scene at 200 texels per unit. [quote=“Neto_Kokku, post:10, topic: 876814, username:Neto_Kokku”] reduce the distortion in the loghtmap UVs

How can I do that?
