UV and opensubdiv questions

CommonOne

Hi,

kind of new to 3d so need some advice, please.

I have an model ready for texturing in Substance Painter. If I want all the UVs together on one sheet, thus one TextureSet, do I have to attach all the objects together and then UV? Then all the subobjects' UVs will be separate and on one tile?

Also - if I do have to attach all the objects together  - some need turbosmooth or opensubdiv and the others don't. Seems like when I attach smoothed objects to non they all take on the smoothing. Is there a way to just apply to one subobject.

Thanks for helping a rookie out!

Don't attach anything. Just apply a Unwrap UVW modifier to all the objects. This will create an instanced modifier that can be used to unwrap them all at the same time. After applying the Unwrap UVW modifier select each object one at a time and move the Unwrap mod under the Turbosmooth / OpenSubDiv modifiers.

Turbosmooth destroyes uvs , opensubd preservesvthem to an extent , wich means u better check if is all OK with the UV after applying it.
