Ptex Displacement from Mudbox

[FSGFX]

any news here.?
you should have all files now.

We got the file. Thank you.
We are currently looking at it. As soon as we have any update we will get back to you.

Once you guys resolve this, please post the results here rather than going through PM. This is an issue others will want to learn from.

Thanks!

solution is this tutorial
http://docs.chaosgroup.com/display/V...PTex+Textures#

a higher texel density for the ptex map...
set the displacement bound to explicit and set the min max values by hand...

[FSGFX]

you should take a second look at your ptex code....
no surprise but renderman is much faster in loading the file and you get the exact same shapes you had in mudbox...
im still not able to get rid of small artefacts in vray...

Like you said, no surprise there... Ptex was written for RenderMan, after all - it would be extremely surprising if it didn't work well.

In general though, displacement in RIS seems to have other issues - I couldn't get it to produce smooth normals and there were gaps between different tessellation levels; this was with regular textures though.
