Hi ZacD!
For this example, I’ve searched for the quick way to do it.
First the 3d modeling I did in Autocad, since architects usually work a lot with this program or Revit.
All architectural geometry is united, that is, it is a single solid.
In 3ds Max, I separate all the outer faces as a piece, and then apply the chamfer to all the remaining geometry and they will be concave or convex.
Then for example, I select all the ceilings along with their chamfers and I leave it with SM_Techos, I do the same process with the floors. The walls are left for the end as it is faster to select and be able to separate them together with their chamfers. In the latter case, I’m building lots of walls so that the resolution of lightmaps are similar in all cases.
The truth is that it takes longer to tell than to do it.
I have used for all Lightmaps pieces with 1024x1024 resolution without compression.
By the way, I do not know if anyone has happened to it, but if I use 2048x2048 resolutions without compression, there are always some errors when loading those maps, so I always try to create pieces for 1024x1024 maps.
Has this problem ever occurred to you?
A greeting.
