Bad quality after baking

LoicDigitalArt

Hello everyone ! I wanted to do a test of baking in using one part of my model but I don't understand, why the quality of my bake on Substance Painter is so bad...

• All my UV have a texel ratio of : 1339 pixels by meter, and i follow a texel ratio of 1080 pixels by meter (so i wanted to bake in 1K)
  
• All my UV are neatly aligned on Blender and there is none overlaping

In wishing you a very good day and thank you very much for your attention about my problem!

at 1339px/m a single pixel is roughly 0.75mm 

soo... if your threads are eg. 3mm thick then you only have 4 pixels to play with.  that's not a lot of pixels - especially if you're trying to represent something in a normal map

I feel like we don't have all the context to fully troubleshoot this-- how much of the 0-1 UV space does this poorly-baking area take up?

this came to mind hope it helps?

Hello everyone, sorry for my late response ><" and thank you very much for all your reply! 

poopipe : I calculed, tha represents 1,339 Pixel by mm, for a mesh having 4,72 cm of lenght and 1,6 cm of width, i thought this was adequat for 1024pixels by Meter ^^"

Joopson : Like this part from my model is little, she takes a little space

Iam77 : Sadly, i was already in 4K resolution for my document ^^

If you need the detail, personally I'd say make them take up more space. Or accept the lack of detail. The bake can only include what the pixels can display, after all.

^^ exactly that 

eg.  to represent a simple hard bevelled line you need 3 pixels - to do anything more interesting you need a lot more space.  I'd probably scale that up 4-8 times
