Texel Dencity question.

Hello, I have a few questions about texel density.

I have a model of an industrial air conditioner and my task is to make a texel density of 20.48(+-3 px/cm). I tried to set this value in Rizom UV, but at 2k texture the value is about 14-15, at 4k it's about 30... But in the test, the deviation from the tesel value is +-3. Maybe I need to redo the UVs? Or do I need to make a multiplay uv (for example, one for a transparent mesh of an air conditioner, the other for a body)

    Sounds like it's giving you the texel density if you were to stay within 0-1 bounds (no tiling) with those texture limitations. You can scale your uvs past the 0-1 bounds, overlap etc to get the 20.48 value.

    Using something like textools helps visualize this, you input the desired TD, what texture resolution being used, and it'll scale the UV shells with respects to those two values.

    Texel Density is the sum of a function that has three parts:

    -Texture Size

    -UV Size

    -World Size


    If your TD is too low/too high, you need to scale up/down one of these. In your case I will asume that you can't resize the model so make the texture larger or make the UV's span multiple tiles.

    Thank you! 

    I achieved the desired result by making a large number of overlaps. And I split the model in half, created Uv and made symmetry.
