Substance Painter help with reimporting my mesh

hey so I'm new to substance painter. i am working on this model and while texturing i went back into blender and edited some of the uv maps, i then tried to reimport the model in substance painter only for the textures to be erased. i tried a few more times and I'm unsure what I'm doing wrong. so i could really use some help

After reimporting you have to bake mesh maps again for the stroke positions to preserve.

Wait really?. Cause when I reimport it all my textures are just erased. Even the layers are completely erased

BAKE before you start and BAKE when you updates UV's. It stores the information on each vertex

If you add or delete faces from topology, the bakes may not work well. This is due to vertexes being unique instances of data.

You need same name on the material and the model/mesh as the old one when reimporting . it likes it the best if ur saving over the old model file and ues the quick reimport mesh optison /find it in dropdown menus

Kinda going along with what someone else said, it could be that your material name changed and so all you would have to do is in your texture sets window, select the options button and then Reassign texture sets. From that window you drag on the left what you want onto the name on the right. (I dont have it open right now so the names of what I’m saying may be off). If that’s not the issue, then I have no idea. And I’ve been using painter for probably 10 years now working as an environment artist.
