Vray displacement to geometry?

[gustojunk]

Is there I way to convert the Vray displacement mesh (that Vray uses for the rendering) to actual geometry. I know Maya has a feature to covert displacement to geometry, is there something like that in Max/Vray?

Thanks

Max's default mesh displacement modifier works, but none of the rendertime displacement methods lets you maintain the displaced mesh. As Vray's displacement is generated rendertime, the same applies to this.

that's what I thought... But, This mesh at rendertime exists, even if it's for a short time. Could it be possible to save it to file like a irradiance map gets saved? Vlado?

PS: The reason for such requests is because this feature would allow me to add detail to models as displacemnt and then be able to build models with the same detail exporting an STL file of that mesh to get an stereolithography prototype. This would be VERY usefull for my workflow, I would say REVOLUTIONARY, rather than just useful.

I would like to see it as an option too, but people thought I was crazy before when I asked. :P

The complete mesh doesn't really exist all at the same time at rendertime, only the part needed to render the mesh in each bucket exists while the bucket is being rendered. The mesh resolution also changes depending on resolution or the rendered image, how close the camera is etc. Since VRay displacement isn't really designed to ouptut a whole mesh at one time you would need a whole new set of features to control mesh resolution etc.

I would imagine you would be able to do this with max displacement though, if you tesselate the base model a lot first. And if you have enough memory....
