(Looking for someone I can send a quick message here and there on Discord or another app to get answers when I get hung up on minor issues. Google works sometimes, but it can be hard to find a specific answer.)
I have this deco I am working on. I'm trying to practice using a specific Texel Density. The 2 meshes for this deco on the left only use half of the 2048 texture space. Do I leave the wasted space? Do I scale my textures up for more detail? Do I use two 1024 textures instead and scale some UVs down to fit? Any feedback is welcome and appreciated. Side questions: Do my UVs/topology look good? Should I use layout instead of manually arranging UVs? Is my Texel Density accurate and is 5,12 a good choice? I'm interested in the MOST common game development practices. If there's a more commonly used Texel Density I'd like to know it to practice in.
More materials = bad (unless there's a good reason)
Using up empty texture space with unrelated assets = usually bad (cos streaming)
Inconsistent texel density = bad when not done for a good reason
There are a huge number of caveats and considerations that come into play within the wider context of a game. The only "safe assumption" for an individual asset with no context is that you should endeavour to use the smallest possible single texture page for it
This finial piece is likely to be high on a wall, or under a table. Good to remember when making assets for a whole game level.
