I'm not in front of my computer but here is what I would try :
If you apply a "Unique Uv's" to your subdiv.mesh (from the Property menu)
and use it only in the rendermap UV option then it should work fine.
When the map is rendered, you juste have to apply it with this "Unique Uv's"
projection.

Objet : [RenderMap] Subdivision surface UV ?
hi everyone
I think everyone wanted to Rendermap something on Subdivided surface.
In my case i got an object in subd level 2 ( via geoapprox ), and i want
to bake the result of a specific shader ( let's say Dirtmap ).
My UV's are done, because i get bitmap too.
My first reflexe was to generate a new set of UV, via Unique UV function.
I seted the target resolution and UV spacing.
Then i ran rendermap, but the result got artifact, or bad interpolation
when i m viewing object at subd 2.
Well classic.
So Are there in workaround ? Any suggestion to solve this ?
What i was thinking to do are :
* Render a pass with my Dirtmap, and reuse it via camera projection
directly in my material.
* Subdivise my mesh at 2, and do the rendermap there. But how Can i keep
UV's of bitmap on this mesh ?
* Vertex color bake ? Yes but rendermap process disable geoapprox. And
there are no way to store different 'Vertex color level'
Any suggestion ?
thanks.
