Merge meshes within Unity before lightmapping?

Questions & Answers
1

Does anyone know if it is possible to merge meshes within Unity and then lightmap the result?

In the project I’m working we are using small building blocks to create the levels. This leads to quite “buggy” looking lightmaps, since each object gets ambient occlusion on its border edges applied, but for i.e. lot of road blocks that make up one big roads we don’t want this.

Thx in advance,

Sorry, I don’t think you can do that in Unity, what we usually do is setup the Geo in a 3rd party 3d application like 3DS max or maya.

Yes, it is possible but it involves complicated process of recreating your assests from scratch via code. Can’t give you more details than it’s possible.
