Mudbox Displacement Map Issues

Alex1

Hi guys,

Could someone please help me out here?

I can't seem to get good displacement map results in Mudbox. 

The image below should be quite self explanatory, but basically, no matter what I try in Mudbox I keep getting extreme value contrast / differences in the displacement bakes. I've tried baking both EXR and Tif files at 32-bit FP and importing the target mesh as an FBX instead of an OBJ, but none of this helped.

xNormals and Zbrush seem to produce decent results even though I'm using the same mesh and settings. I realise I could play around with the levels in post, but if possible, I'd really like to find out how to correctly bake in Mudbox.

Thanks!

First off, the good news is that it is definitely possible. A couple things you might want to do :

- Use TIFF
- In Xnormal make sure that the whole range is covered in the "post bake" displacement dialog (no red/blue clipping), and maximize your values so that your min/max are simple integers.
- Back in mudbox you'll then be able to apply the displacement by using .5 as mid value and working out your multiplier based on the range you specified in Xnormal.

Here's an example of a sculpt baked to displacement in Xnormal and re-applied to a (very blobby) base back in Mudbox. Even in this extreme scenario all the surface information is recovered and the distances are correct too.



Keep in mind that displacement is dependant on object scale, so be extra careful with your transforms and your scene setup.

Thank you very much Pior.

Going to give it a try.
