3DS MAX Texture resolution

Filip5

Hey, I am having really bad quality textured model. The thing is, its blurry even at 4k... What would be the best to do ? 

I am using 3ds max 2015, and substance painter for texturing.
I know blurry textures may be caused by too many small unwraped objects etc.
 I ve been thinking about using multiple UV in max, but have no idea how that works. Alredy using multiple materials and IDs. Any idea how to fix that ?

Multiple ways to approach this.

The biggest savings is from overlapping and mirroring UVs, so you UV just one side of your escalator, then re-use the same UV for every side.

You can also use tiled textures, and blend them together to hide seams & repetition.

You can also use decal trims.

Looking at your UV sheet your islands are tiny. You're only using about 10-20% of the space, which gives you an idea of the very limited amount of pixels each island will receive.

As well as the great methods @Eric mentioned, the elements are clones of eachother so you could just unwrap one of them, bake, texture, and duplicate in your scene as you would for modular pieces. This will save the step of offset-baking as the UVs will automatically overlap when you clone the mesh.

You can take this further by just creating 3 or 4 steps instead of the entire staircase and using the same modular approach. This way you don't have such a large object to try to fit on your texture sheet.

So I solved this with breaking the mesh into multiple pieces. It wont solve my problem completly, as one ca't separate huge models such as train,etc., but it helped me for now. Thank you

Yes, you can texture huge objects, and not use 4096 textures.
