What is Texel Density?
Texel Density essentially exists so that when you come to UV modelling a 3D object, you can have the correct scale of texture’s for size and resolution purposes.
Why is it important?
Texel Density is important because if we’re creating 3D assets for a game or for a movie, you wouldnt want the textures to look as if they were stretched or looked blurry. By understanding Texel Density we should be able to create clean looking textures that look as if they are to scale and not stretched.
Why do we want to maximize Texel Density?
By maximizing our Texel Density, this will result in finer, more crisp looking textures. If we’re looking to create a realistic effect, we are going to want our textures at maximum resolution and UV’d appropriately.
Below is an example of what good Texel Density looks like and what poor Texel Density may look like. (Source)
