Is It Impossible To Fix These Lightmapping Artifacts ???

LIGHTMAPPING SETTINGS
Lightmap Resolution: 100
Compress Lightmaps: Inactive
Lightmap Parameters: High Resolution

LIGHTMAP UV SETTINGS
Hard Angle: 88
Pack Margin: 64
Angle Error: 8
Area Error: 15

Nothing Solves This Problem… Really?? Is It Impossible?? If so, unity lightmapping is a garbage… If no, please show me. Thanks!

Hard angle 0

pack margin, try something like 8.

Thanks for answer. I will share result.

result is here. I don’t know how can i comment this. I would want to hear your opinion.

Can you share the scene so I can try things? I think that looks slightly better but still pretty bad. Maybe a little higher pack margin is needed. (Personally I would manually author the UVs)

Are these rocks generated in unity? If no, then you should create UV maps in program like blender, turn off automatic UV generation in unity and never bother about this “feature” again.

How can i create uv maps for unity lightmapping in blender? I can’t find a good source.

I would want to send scene. But i don’t want share public. How can i send message to you? i can’t view your profile.

If you want, send me an e-mail at (email removed)

I’ll be able to look at it tomorrow at the earliest though.

Lightmapper takes your original uv map unless you select to create a separate one in the editor. So all you have to do is to google “blender uv mapping”.

To be clear, you don’t have to choose blender for uv mapping, every single solid 3d modeling tool supports uv unwrapping.
