Hi, I sculpted an impact crack on a wall to use it as a decal texture for a vfx task I have atm
As expected of Zbrush the sculpting of the crack itself went smooth and magical.
But then when I baked and exported the normal, displacement and ambient occulusion. They all have what appears to be the topolody of the lowest subdiv drawn in the textures.
What is this and how do i get rid of it?
I wanted to post the texture here but new users dont get to do that 
Hi @Hirothepanda, welcome on ZBrush Central!
so if you use the normal map genaration from a multi resolution subtool, you will likely have to enable the SNormals button (smooth normals) check into the Export options > Normal map settings.
Hope it helps,
Nicolas
Hi Nico!
Thank you for helping out, but it seems that didnt solve the problem, I really wish I could upload pictures to show you whats going on…
This is the exported image, fyi I have the green channel flipped.
I hope this could show you the problem
