support for realtime displacement (adaptive suvD)

[FSGFX]

looks like vray does not support the new adaptive subD in the viewport...
this is also breaking the viewport diplacement... it does work if i use a blinn shader...

This type of subdivision is supported with V-Ray, only it's disabled by default. You can tick "on" this option in Render settings > Overrides > Geometry > Viewport subdivision.
For viewport displacement, if it's done by the shader it should be supported. If you're using V-Ray's displacement node, there's an option to tell it to use the displacement shader (VRayDisplcament node > "Override Global Displacement") and it can be used in combination with all the displacement control attributes that can be attached to V-Ray's displacement node.
If you have and example scene where this doesn't quite work, we'd be happy to have a look.

It seems that we actually don't support this, I'll log it as a request. For the moment this won't work with V-Ray, unfortunately.

thanks... would be great to get this working...

The OpenSubdiv library does not support adaptive subdivision in its CPU version; last time we checked, the adaptive mode was only designed for viewport previews. Pixar made it clear they will not help other renderers by adding the functionality to the CPU version and it would be up to us to reimplement everything. Maybe things have changed since, I don't know... For the moment, if you want view-dependent subdivision, you have to use the V-Ray subdivision attributes.

thanks for reply...
rendering the "standard" subD is fine... but id like to see the displacement in viewport using a vray shader...

Ok, this may be possible, we have to check.

We will look into this once the 3.5 release is out.
