plain and euh… simple…
I sculpted and painted a model but used ptex instead of uvs for good reasons (at the time)
I made sure that rendering in Vray was possible with ptex (for vector disp and paint)
this way, I end up animating a low rez obj mesh in 3d max , textured with ptex paint and displaced with ptex vector displacement map…
it works fine but…
I 'd like to switch to an other render engine which DOESNT support ptex (nor vector displacement)
(for vray rendering of vector displacement and ptex paint you have to use vray proprietary functions which are disabled when using an other render engine)
So… How can I transform my 8+millions faces model from ptex to uv ? is that even possible?
the solution has to be able to read a multi subdiv model (base mesh and the hierarchy of subdiv up to level 6)
and give me the ability to reorganize mapping from poly to ptex tiles into poly to UVs
I was even ready to toss the displacement and directly animate the 8 millions face model (driven by a low detail mesh, with skin wrap)
but even with this workaround yet I can’ t retrieve the paint because for this i d need to transfer paint from the ptex high rez model to a hi rez model that I d re- uved
And it 's virtually impossible to build UVs on a multi million mesh.
(neither “3d coat” nor “unfold3D” unwrap functions can really handle such a monster mesh. Not to mention it s a manual work I couldnt handle )
is there a way out or am I stuck with vray? (NB: i wanted to render in “fstorm”, which doesnt support ptex yet)
