question about match by name in substance painter

ibbi

hi, im having a brain fart right now so this is going to be a dumb question. i made a shoe consisting of 3 parts, the sole, the main body, and the tongue of the shoe, which are 3 different meshes. i made a high poly version with details to bake down onto the low poly, and i want all 3 low poly parts to use the same one uv map. however the only way i know to get them all on the same uv is to attach them together to create one object (this is in 3ds max btw), and by doing so i cant name each of the 3 pieces since they are 1 piece now which means im going to have to explode the mesh to avoid any baking errors. could someone help please

You don't need to attach those three objects together, you can keep them as three separate low-poly mesh. However if you want them to share the same UVs, you need to assign the same material ID on each of them. This way in Substance Painter you can use the "match by name" feature for baking and have all the meshes under one common texture set.

oh i see, thank you very much!

And to add to that, just export an .fbx with 3 separate meshes with unique names for the sole purpose of baking but keep your original mesh(all 3 elements still one mesh) and use this to apply your textures.
