You didn't get my point. when i use Unique Uv's projection WITH geoapprox there
are some artifacts.
Do a simple test with a cube at subd level 2 you will get my point.
Why i do that ? it s just for speed rendering purpose.

Ah ok.
But you can use the "Unique uv's" only for maps that are creat by XSI (like
Dirtmap/photon/shadow etc.)
and use your "hand made UVmapping" only for the maps that you want to
completly control in a paint programe.
Why do you want to use your UV mapping for dirtmap for example ?

yes but i loose my previous mapping, if i create the new subdivided mesh. i
don't want that.

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.
