UV Mirroring In 3D - Coat

[SlipperyBrick]

This would essentially be a mult-material object. Again, I’m not sure how 3D coat handles this as I use 3Ds Max. In Max if I assign a material to specific polygons then those polygons are not affected by any other materials. This means that I can scale and have those UV islands however I want in the same UV as the other parts of the mesh. The mesh will still occupy the UV1 space along with all the different pieces. They do not matter if they overlap because only the materials assigned to those UV islands will be represented for that particular material ID. The second UV will still be the lightmap in this instance. If there is a problem and you have multiple UV sets you can always manually assign the lightmap. It doesn’t have to be the second UV. This is default. You can change this in the Mesh viewer/editor by finding the lightmap coordinate index and changing it to the one it should be. Just remember that it is a zero based list. In UE4 you’re UV 1 will be UV 0.

Awesome Tim. Thanks for the clarification I completely understand now

I use Silo 2 for box modelling simple geometry (like the layout of the levels). You can assign different materials in there to, it took me about 3 days to figure out how to do it but I managed to get the problem solved. Very excited to try out the lightmaps though, from all the help I have received I think I’ve finally managed to nail down my workflow

@WillBellJr, in regards to the resolution of your UV set it’s best to keep the lightmaps between 8 - 128 for resolution, that seems standard anyway. Higher resolution will look nicer but impact memory more. You can have multiple UV set’s at different resolutions as well and this will cause no problem. Each UV set is it’s own unique UV set/channel
