Textures have seams around UV-islands after import into UE4 #157

v0.6 (2019-06-27) The textures look fine in armorpaint but have small seams around the UV-islands after importing them into UE4.

Yeah, this has been hanging around in one form or another for a while now, see http://forums.armory3d.org/t/pixel-bleed-fix-needed/3218

There is a way to stretch brush strokes using Paint Bias option in preferences (a value above 1 can be entered manually), but in that case UV-islands need a bit of margin. Will try to make it a little smarter soon so there is less need to tinker with that option.

Edit: Should maybe rename it to Paint Bleed?

PixelPartner commented 5 years ago

Renaming it to Paint Bleed would help. And an on screen explanation even more.

I think extending them indefinitely in the margin-space until they hit other island's extension would be a good solution (in an approach similar to voronoi).

Yeah, something like this would be great: https://docs.substance3d.com/spdoc/padding-134643719.html

Here is a Gimp plugin to do something similar: https://polycount.com/discussion/114616/uvpadder-filter-for-gimp-2-6

https://docs.substance3d.com/spdoc/padding-134643719.html it look cool (wow feature) :+1:

Preferences... - Usage - Dilate Radius option is now available for generating padding when painting. New builds up soon.
