VRScene in Max - Extract?

V-Ray V-Ray for 3ds Max General

Hi all

Is it posssible to extract mesh from a vrscene file, similar like it is possible from vrmesh file?

I need to import vrscene, but also need to be able to modify/move individual items in the vrcene

There are override commands you can put in your vrscene object… not easy to use right now however though…

Great. Hope it gets easier soon

There is one less than convenient way, but still it should work. You can use the ply2vrmesh tool to convert a vrscene to vrmesh, then import the vrmesh in max and restore it. For some time now the ply2vrmesh tool has been able to convert vrscenes and if you know the name of the object you want to extract, then you are in luck (you will have to know the name, otherwise it’s guesswork for large scenes).

Here’s how it works, the ply2vrmesh has some vrscene specific commands.
Start the tool in a cmd window (usually “C:\Program Files\Chaos Group\V-Ray\3dsmax 2017 for x64\tools\ply2vrmesh.exe”)
Use ply2vrmesh <yourScene>.vrscene -vrsceneList
Now you should have a list of all nodes (objects) in the vrscene. If the scene objects are named properly, then it’s easy (otherwise you’ll have a list of object1, object2… object2002).

Then use ply2vrmesh <yourScene>.vrscene -vrsceneNodeName <nameOfObjectToExtract>

This will save out a vrmesh file at the same location where the vrscene is, and you can import it as vrayProxy in max and restore the mesh.
Here’s a short video of how this works: https://youtu.be/9yvZ2HTINfE

WARNING: This might not be the cleanest of workflows, just letting you know in advance in case the mesh breaks unexpectedly after being restored :slight_smile: I seem to fail to convert it to poly, although editing it as an editMesh seems to work fine. For some reason, converting to editPatch and then to poly works just fine :slight_smile: Hope this is helpful.
