Hi, Esenthel!

Are detail maps normal maps that are additionaly applied to main normal maps? Or are they something else?
Sorry, I didn't find anything about the purpose of detail maps in the manual.



SONB

they affect color maps only

they increase quality of surfaces when looking from closeup.

normally the main texture gets pixelated/blurred very much when viewing from closeup, but thanks to detail map the blurriness is less visible.

(just add a detail map to a already created material and play around with "detail scale" and "detail power" parameters in the material, you'll set that it will have better quality from closeup)
