hy blenderheads,
im from germany and since 1 year on learning blender - this is my first Post
excuse my little bad english 
i work on the character “captain blender” from the blenderbook “Introducing Character Animation with Blender”
i use blender 2.49 on windows
i ran into a Problems with overlapping UV´s when BAKE AO for more than 1 part of the mesh :eek:
…i try to describe…
ive got a char out of one mesh with 3 Materials
mat1 - HEAD skin
mat2 - SUIT
mat3 - SHOES plastic
SKIN creation for the head.
-
ive UV-unwarpped the head (with good seams)
to fill a whole 4000x4000 Picture -
then select only the heads Vertices in 3D-View
-
open UV/Image-Editor - ADD new (empty) pic
-
goto RENDER - BAKE - and bake AO
THIS FIRST TIME EVERYTHING WORKS !!
blender bakes the AO to the pic in the editor for just the head as i had expected
then it stops
------ 2nd part
SUIT creation for body (on the same mesh)
-
i UV-unwarped the suit´s vertices with seams
to fill a whole 4000x4000 Picture again -
then select only the suits Vertices in 3D-View
-
open UV/Image-Editor - ADD new (empty) pic
here occoured my first problem:
when i add a pic it dosnt show up in editor
the acctual pic hangs there - i cant change the pic in the editor
when i pin the acctual pic to the editor i can change pics :no: ohh whats that ?
so i do this (unlogical) and select the empty pic i created earlyer -
goto RENDER - BAKE - and bake AO - let it run
THIS TIME Blender BAKES other parts of the mesh NOT THE SUIT
seems like blender do it evertime i try in a differnet order
it mostly starts with the suit or head and then jump to another part while baking
or another time it bakes the head and stops - but never the suit
i dont understand that and never experienced something similar chaotic
MY QUESTIONS - but it seems to be another problem
do i have to mark edges between the different MAT as seams maybe ?
or do i have to avoid overlapping UVs on the same mesh even with differnet Materials ?
or do i have to use more then one UV-Tex-Layer ?
have all UVs to be on one pic ?
PLEASE HELP :eek: i realy cant figure out whats wrong here
many special thanks
tobi
