I have a little problem here with my models.
Recently i discovered Substance Painter,a beautiful texturing program for 3D Objects.
Now,i have a problem with Unreal Engine (my version is 4.10).
As you can see from the first image,the model is divided in 4 UV Maps (Glass,Material_Exporter A-B-C).
However,when i import it on UE4,one or multiple UV Maps gets messed.
Obviously,all the textures are exported from Substance Painter with the “Unreal Engine 4 (Packed)” Preset,so i really don’t know what the problem is.
The only thing i noticed is that models with only one UV Maps are imported correctly.
It looks to me like you just don’t have Materials B & C assigned to the elements. In your Static Mesh editor, you should have multiple elements in the LOD0 section at the top of the details panel:
You likely don’t have anything assigned to Element 1 & 2.
OK, I see that you have 3 UV channels. One for lightmap, and 2 for your actual materials perhaps? You’ll have to set that in your materials by adding a texcoord node then changing the texcoord’s UV Index value (without a texcoord node, it defaults to index 0):
You need to change it to the UV channel number that the texture was applied to. This is something you would have chosen in Substance Painter (or similar software).
