costs associated with UV seams?

Noth

Could someone point me in the direction of some documentation in regards to costs associated with UV seams?

Q: Is there a list of good rules of thumb out there?

eg: 1: It is generally considered good to minimize the number of UV seams you have? 2: Place your UVs on your hard edges. 

Thanks!

If you're developing for modern pc or console it's a drop in the ocean and can basically be ignored 

Basically,  every vertex on a seam is duplicated for ever shell it is part of. Its the same with hard normals

Worth considering for mobile? anything that comes to mind that I can read up on? Thanks for the response.

More important for sure but in practice not something you'd need to worry about -  other, more important factors will govern how you split up your UVs

This is gold though ..
