To be clear, I know how to unwrap and I've watched quite a lot of content on how to do so in efficient ways. However, I have been putting together some decent-sized buildings for an urban city project I am working on and I am having a lot of trouble with texel density. Most tutorials on the matter end with the person taking all of the different objects and then combining their UV maps into one. For me, it feels like even if I get the islands as efficiently packed as I possibly can, my texel density just isn't where I need it to be.
You'll find a screenshot of the project at the bottom of the post.
I am currently keeping each wall section separate and then putting all of the windows together into one map, then applying separate materials to each section so that they come up as separate texture sets in Substance Painter. I am getting good results doing this, but I am wondering if there is something I am missing...?
Read more below the screenshot for more details on what I've been doing to this point.
Thanks for any help you can give in terms of larger projects and what the standard practices are. In fairness, most tutorials on UV mapping are working with small objects, so I'm having a hard time gleaning any further information from them.
