Substance plugin for UE4 keeps unlinking my files and making me remake/bake the textures when I send them to painter to edit them (although it still shows that the textures are there). It’s as if it didn’t exist and starts over. What’s odd is that it’s not all my assets but it’s a good majority. Would really like to figure out what’s going on and how to fix this as I am dealing with a large game project and it’s becoming an issue for our work flow. Got some assets with lots of work into them and remaking them just when I’m trying to edit them.
Any help would be much appreciated thank you!
I am running the plug-in on 4.25
@P_White6 ,
Can you post a video or outline the steps you follow in order for us to repro this? 
(Also what version of Substance Painter?)
Sounds good. Thank you.
Substance Painter 6.2.2

The objects in which I am sending to Substance Painter are items I have already textured and Substance is acting as if I haven't already.
@P_White6 ,
If you export something to Substance Painter (or in this case, even click cancel on the second dialogue), the plugin will try create a .spp project and create new blank materials in UE4 for that project. So if there are any materials already applied to the mesh in UE4, Painter would have no idea. That would explain the plugin removing the materials. UE4 materials can't be sent to Painter unfortunately. All the LiveLink plugin does is send textures back from Painter and place them in a material.
However, after you send a mesh the first time using Live Link in UE4 to Painter that .spp project will be placed in the project folder (along with the textures). So any other time you wanted to send it, it would see that project and wouldn't reset the materials.
Hope that makes sense
Bumping because I need help and it's apparent I wasn't clear so here is my step by step workflow:
- Import FBX into UE4
- Right Click on FBX model to send to Substance Painter through the live link
- Object is imported into Substance Painter
- Mess with baking settings
- Bake the FBX
- Texture my FBX ( at this point I can see the live link is working and the textures are showing up)
- Save item
- Move on to the next FBX
-- At this point for the sake of communication let's say I save my UE4 project and exit out. I come back the next day and I go to that FBX model that I was texturing in painter and I want to add some more details but this time when I send it to painter it makes me start over as if it doesn't recognize that I already textured it in painter (much like the video I posted).
Would love the help. My company is using this program for our project and I'd hate to get so far creating our levels and having to restart again.
