Make proxy from displacement object

[Morne]

Hi all

On my test renders my pc is almost dying on res of 1280X720. For the final I need to push it up to 15000 wide (for a billboard). Is there a way I can make a proxy out of my object that has VRay displacement mod on it? I have a cobblestone road and the displacement is seriously eating into my 6GB ram. I also have a huge limestone wall also with displacement

Here's my settings for the road and the wall (with the exception that the wall has a different map for displacement and the amount is 100mm)


Any tips?

Use Zbrush to apply your displacment? Then save out high-res mesh, then convert this to Vrayproxy in max.
