No readme in original mod, so I'm crediting Rhymer.

Simple transform>translation of the x-axis (-30) using nifskope.
Not my mesh, not my work, just an edit.
Let this mesh overwrite the one from the main mod.

Comberry;
Lucas9:"For everyone who has issues with the white bark after picking the comberry: rename the "bark.dds" texture to "md_vurt_brazbark3.dds". That's the name that appears on the Warnings.txt about a missing texture."
So now you'll have a "bark.dds" and "md_vurt_brazbark3.dds" in the texture folder.

I guess I could have just renamed the texture the picked comberry mesh calls for, but I don't know why it was named "md_vurt_brazbark3.dds", so I didn't want to mess with it in case there was a mod that does have that texture and the user wanted to use it.
Easier for users to rename textures than edit meshes.
