so you have to try to paint over the seams again with different bleed values
It's what i did even with a vcalue of 10 !

Ok i've tested with a model entirely made in Blender !
The Bleed is taken account !
I think the problem is alos the BLender display,
caus the more i zoom out , the more i see big seems on the mes ?
Strange !!

I must come back to Blender 2.49 without precise texture paint , but no seams paint problems ??
