SUBD tag not smoothing uv's

Hi there,
I've got a problem with a character that has displacement applied.
When I put the octane object tag on and activate the subdivission It smooths the geo as expected but not the uv's so I'm getting very blocky looking displacement as it's based on the proxy mesh rather than the smoothed geo.
Any help would be greatfully recieved, is there a smooth uv's option somewhere i'm missing?

Many thanks

Hi,
I'm not sure to exactly understand the relationship with UVs as it sounds like the mesh's normals instead.
I believe that what you are looking after is the "Smooth" checkbox in the Octane materials.

Hi there,
Thanks for the reply.
No it's not smoothing, that's on the shader, this is related to a geometry issue.
I have a proxy mesh that I'm applying a level 2 catmull Clarke subdiv to via the Octane object tag.
The subd is working fine and smoothing the mesh, unfortunately it's not smoothing the uv as well so with a texture applied it is very blocky as its displaying it through the proxy UV.

Any help from anyone on this issue would be very much appreciated.

Many thanks

Due to NDA restrictions I can't post it at the moment but I have found a fix for the problem.
If I apply subdivision via the standard c4d subdivission methiod and drag my object inside and then set the subdivide UV's to standard it fixes the issue.
This isn't ideal as as the uv smoothing (for octane at least) is based on the mesh smoothing that is happening in the editor! not on the renderer.
A bug there to be fixed I think.

All the best
