one question. does that normal map include the height AND normal channels?

i dont want a separate height map

5

Normal maps are so to speak relative and height maps absolute and so two different things…

6

No. Normal map is information about relative angle, and height i just height.

Software as SubstancePainter to some extend can generate one from another. (rather height>normal)

7

so how would i use the height info in blender?

8

What for?

Just for rendering as is from painter? Dont, information from painted height is already in normal map.

thanks. that helps.

oh and if you could answer a related but different question.

its a chair. it has a metal arm and a plastic body. i plan to sell it as a game asset on CGTrader and similar places.

For now i have exported Base Color, Normal DX and OGL, Metalness, Roughness and AO maps. Should i also include a specular map?

No.

Unless its Specular F0, then its different workflow.
