Re-texturing the section of tree model and using this free 2k tree texture map from the following awesome link.http://kirkdunne.com/blog/?attachment_id=233
I've created a normal map from this texture, in Photoshop and have applied both the texture and normal maps in Maya.
Then I've exported it into Mudbox, created a new paint layer, created a stencil with the image and then used the projection tool in the paint settings to paint the texture directly onto the branches. This will enable me to rotate the texture (rather than the UV) so I can make sure the grain of the bark is rotated correctly, as per the orientation of the branches.
Texturing in Mudbox. I've changed the wireframe colour to green (just a personal preference as it's similar to Maya in appearance).
Image below shows the geometry selected, with a new paint layer. A stencil created from the 2k image and the projection tool.
The stencil appears as a flat image on top of my geometry; I can then use my graphics tablet and pen to 'paint' the stencil onto the tree. Once I am happy with that section I can rotate, scale, move the stencil and paint again...
