Author Topic: Normal maps don't work with legacy UV Tile Workflow  (Read 724 times)

I have big problem with new Substance Painter 2020. I used previous versions and everything was ok. Now we have new option for UV tile (UDIM), and we can paint across UDIMS. But if I would like to use previous (legacy) settings, then there is a problem with imported normal maps.
Here is an explanation:

For example, I have a model of the box, and imported it to SP with new UV Tile workflow (painting across UDIMs)

The box has 4 UDIMs, 3 UDIMs for 3 separate sides, and 4th UDIM for rest of the sides

Now I'm importing normal maps, and they has been imported as one pack (there is a thumbnail with a number of normal maps)

When I put it into Normal Map slot to bake Mesh Maps, then I can see all maps matched to every UDIM - everything works fine.

Something is different when I use legacy workflow

When I use pack of imported normal maps for first UDIM, then it shows correctly

but if I use it for another UDIMs then SP shows first normal map for every UDIM

Why it can't be matched correctly like with first workflow? I can't use normal maps for other UDIMs because it shows only first normal map (1001 UDIM). What should  I do? Even if I import every normal map as a single map with a different name, they don't show on my model at all. In previous versions of SP there was no problem.

Thanks CAGameDEV for the answer, it is not an exact solution to my problem, but thanks to you I tried to change names and when I deleted all UDIM numbers then it started to works. So I can't put UDIM number in my normal map names at all. This is so stupid, because when I use legacy workflow SP should works like previous versions - and all maps import as single maps, not as one pack of all maps - which causes problems because SP can't match them properly. I hope they will fix it. Thank you CAGameDEV.

If you're using Legacy mode just remove the UDIM suffix and import as single maps. Problem solved. I don't know of any other way as you cannot cycle them in Painter as far as I know.
