The option Use object material of the VrayDisplacementMod does not work anymore in the lastest release.
I hope that you can debug it quickly, because I’ve a lot of collapsed objects with multisub material, and displace maps for each sub mat.
(by the way it works perfectly in vrayNext, trouble in v6.10.09)
Don’t you mean 6.10.08, the latest official build? Anyway, I’ve tried official, latest stable nightly, and internal nightly and cannot reproduce the issue. Do attach a simple scene so we can troubleshoot.
My setup I think was a VRayBlend, which I figured was not compatible or something. So I just combined the displacements outside of the blend and applied that the the modifier instead (disabling the VRayMtl displacements)
Yes, I work on the Nightly 6.10.09 (build 32197) and attach to you a file. And the UI is not disabled when use mat checked like previous version, Blue draw on screenshot.
