If you are agree, I'd like to go ahead talking about UV workflow.
Reading a lot on web, I would like to confront you about some deeper aspects.

The first step I thing should be to do is to divide UV for Hard surface objects (vehicle, props, architectural, ...)
from UV for organic object, clothes. These latter types of UV have a different way will be created, we have to discuss later.

Second step it should be to decide how to create UV map for every specific meshes (3d Obj or parts of it): we have to know/decide which kind of LOD (Level of detail) we need for every object we are going to UV map. Therefore, we have to check the camera animation and we have to check what items need a high LOD and which do not need it.

Fixed these preliminary things, we maybe should proceed with two main approaches to create UV:

a - UV for meshes textured with painted textures;

b - UV for meshes shaded (so, no texture but only applyin material shader);

c - UV for meshes textured with ready made texture from photos.


So, in this way to approach the UV workflow, we can decide how is the best way to make any specific UV mapping.
If we are agree to it, we we may talk about some specific aspects above mentioned. For example:

1 - how to better make UV for painted textures? I mean, what is important? Which shape we have to give to UV to better apply painted textures we are going to apply to this UV? UV should be many pieces, only few or just one whole piece, for example?

2 - how to better create UV for a material shader? If we don't use textures (painted or from photos), but we use a material shader - as far as I understand (but I could be wrong...)- it is not important how are arranged the UV: shading works good without "checking" UV shape mapping, as well.

3 - how to better make ready made texture from photos? Again, if I understand correctly, we should conform to the shape of the photo tho the shape of the UV, or vice versa, create UV shaped to conform the orientation of the photographic texture (bricks, woods, marble, concrete...)

What do you think about? Is it a good approach? Alternatives? Any suggestions?

Many thanks for a reply!
