I’ve baked out a 32 bit floating point vector displacement map to exr (can’t get unreal to read tiff) from Mudbox using absolute tangent (I hope to get this on a deforming character). I’ve seen some examples of people getting vdm to work, but I haven’t had any luck replicating it. From what I can tell, they’re converting the textures to standard png and the like, which loses the precision of the floating point format. Is there any way of getting this to work out-of-the-box in unreal engine?
update - I managed to get the displacement map to work. I had to invert the blue channel then swap the green and blue. Next problem, the displacements are in world space and I need it to displace with the normal
Hello - could you share what your material setup looks like please. I’m having issues getting a similar material to work.
Many thanks,
Paul
