i have a question about displacement. see attached renders for details.
picture 1 octane- picture 2 c4d - picture 3 redshift.
c4d and Redshift are able to fill the space under displaced surface, avoid the discontinuity in nearby meshes.

instead, with Octane the visible displaced surface is in the same position of C4D-RS,
but near borders and corners Octane can't fill the space under that displaced surface.


Thanks in advance for any useful suggestions

Hi Davide,
please, try with 3.08RC2:
viewtopic.php?f=85&t=66106
and in the Displacement node, change the mode to Follow smoothed normal:

Did you use the "weld" function in standalone?

Under preferences/import/OBJ import --> check "Merge unwelded vertices".

I believe you also must increase the phong smoothing angle above 90 degrees.

Hi There,

We had a long chat with the Guys about displacement a lot of issues is fixed but others not yet this issues there is because you texture doesn't have continuity compare to the UV set, Is something the guys can't fix yet because will disturb the optimization of the displacement this the reason is fast at Octane.

They may look at this further right now you can do some rack to get right . The latest version fixed in some cases but I know this one is one of the issues not fixed yet.
Due the fact the value of the texture displacement on the UVs seams changed really fast making this break effect.

hope this help you for me I do the displacement at Zbrush and bake in to a mesh with a topology optimization and I use the new mesh and displacement texture from there.

Hope this help you for now. But again is a know problem if you research Displacement fixes you will see all pages about it.
