I'm having trouble with texture baking in the same scene.

[douglas.addy]

I baked a texture to an object. but when I try to bake another texture to another object it bakes the previous object until I unload the reference, then it works.

Can you post what's logged in the script editor?
For example:

select -r pCube1 ;
# [mtoa] Render to Texture : Rendering polymesh pCubeShape1
# [mtoa] Render to Texture : Rendered to C:/Users/blairs/Documents/maya/projects/default/images/bake/pCubeShape1.exr
select -r pCube1 ;
# [mtoa] Render to Texture : Rendering polymesh pCubeShape1 # 
# [mtoa] Render to Texture : Rendered to C:/Users/blairs/Documents/maya/projects/default/images/bake/pCubeShape1.exr # 

[douglas.addy]

select -r Cube ;

select -cl ;

select -r Cube ;

# [mtoa] Render to Texture : Rendering polymesh CubeShape

# [mtoa] Render to Texture : Rendered to D:/Pro/Pregnancy/sourceimages/baketest/CubeShape.exr

Can you reproduce the problem? First bake one object, then the other.
Then we should have two sets of messages in the script editor

[douglas.addy]

when the reference is loaded I get this (unexpected),when the reference (the baby model) is unloaded I get this, (expected)

[douglas.addy]

its using the uvs of the correct model but its baaking the wrong texture. those are not the correct uv's for the baby.

[douglas.addy]

select -r Cube ;

select -r RenderCamera ;

select -r week40_master_body ;

# [mtoa] Render to Texture : Rendering polymesh week40_master_bodyShape

# [mtoa] Render to Texture : Rendered to D:/Pro/Pregnancy/sourceimages/baketest/week40_master_bodyShape.exr

select -r Cube ;

# [mtoa] Render to Texture : Rendering polymesh CubeShape

# [mtoa] Render to Texture : Rendered to D:/Pro/Pregnancy/sourceimages/baketest/CubeShape.exr

first I get this (expected)

then I get this (unexpected)

[douglas.addy]

it seems to happen when the cubes normals are reversed
