I use Unity2022.3.1 and after optimization the scene and re-baking the lights, the UV of the optimized meshes are not correct. You can see on the pictures.

Hey @Abbas Jafari,

Thanks for sharing the details along with the before and after images, they are helpful in understanding your issue.

To address your problem, we need a bit more information. Could you please provide:

• The version of the Scene Optimizer you're currently using.

I have v1.1.4. 

First, I cleared the baked map data. Then I optimized the scene. Then I enabled the optimized meshes and disabled the original meshes. Finally I baked the lights.

Hey @Abbas Jafari,

After carefully investigating your issue, I believe the root cause lies in the scaling of the UV2s. These weren't properly adjusted to match the new combined mesh, which can, in turn, affect the lighting in your 3D scene.

Attached here is a patch that contains fixes relating to the lighting UV2 data, please download and import in your project. Let me know if this works for you!

SceneOptimizer115-b2.unitypackage

Here's the new Global Illumination UVs before and after:

Here's the new Lightmaps before and after:

It's important to note that while a fix may help your specific issue, there are inherent limitations with Unity's built-in combine method. Unity does not automatically preserve this data, and as such, a custom translation process is usually necessary. Even with available manual adjustments, it's not always possible to perfectly preserve this data due to potential overlaps and inconsistencies in the UV mapping.

Regrettably, this means that we won't have any improvements scheduled to address this in future updates of Scene Optimizer. We sincerely appreciate your understanding and patience in this matter!

Best,
Manny

Hey,
Thank you for the provided packages, but since I'm working for a team and on commercial project, I'm not able to use beta packages. I find the solution in installing another asset.

Hey @Abbas Jafari

Thanks for getting back to us! I understand your situation about not being able to use beta packages for a commercial project. The provided package was intended to test if this resolves your specific issue.

If this fix works, our plan is to incorporate it into a new update for Scene Optimizer. That way, you won't have to rely on a beta version for your project.

Best,
Manny

I tried the beta and I get this error message

Hey @BoBlond,

Could you try removing the Scene Optimizer folder entirely under Assets/Procedural Worlds and try-reimporting the new release (not the beta)?
