Hi guys, sorry to bother you again with silly questions, but as I said in a previous topic, I've started 2 months ago, so there are a few concepts that I still struggle. Every course that I've taken so far, people talk about how saving texture space is vital. So let me give you an example of my doubt. I'm making a scene, and there are 4 props in this scene, say I've defined a texel density of 5.12px/cm. What would be the most efficient way to texture them, putting all these objects in a single UV sheet , and use a 2048x2048 texture (assuming they all would fit in with the defined texel density) , or unwrapping each prop in a single UV sheet and using lower res textures (assuming that the prop would have the same texel density in this low res unique texture than it would in the texture with all the props together.
Also, if I decide to use a single 2048x2048 texture and texture all of the props together in Substance Painter, should they all be in a single texture set for the process to be efficient? Because than I could use the same maps (albedo, normal, roughness, etc) for all of the props, on the other hand if they are in multiple texture sets, substance would generate maps for each one of them, even if they all fit in the 0 to 1 space together. I guess that my main doubt is: When we are talking about optimization for a game, what is more relevant, the number of uv sheets that you will be using, or the number of maps that you would have to use on a scene?
Sorry for the long text, and if my question sounds confusing. Thanks in advance
