Max Script to load render preset in Vray Volume Grid

V-Ray V-Ray Common Public

Hi,

the subjects says it all, is there any function that would allow us loading a .tpr preset after creating a Vray Volume Grid object ?

This has to work on Max 2016.

Thanks !
Chris

Hey,

There is such a function for Phoenix but the Volume Grid does not have such maxscript interface currently. Doesn’t look like a lot of work to add it. You need it for V-Ray 3 if I may guess?

Cheers!

Hi, thanks for the quick reply !

I need it for Vray 3 indeed. I can see from the .tpr how I can parse through the file to get the values to apply but since there is multiple type and kind of values as well as the values for each frame, it’s a bit of work that I wanted to avoid as I would have to test it out a few times to make sure my stuff is actually working correctly, especially the ramps.

Cheers
Chris

Sorry, something I forgot to mention, I actually don’t really need Max Script, but I believe there is no Python functions yet for VRay so I’m using it this way :

result = MaxPlus.FPValue()
    evaluation_success = MaxPlus.Core.EvalMAXScript(“VRayVolumeGrid()”, result)
    vray_node = result.Get()

rendinput = vray_node.GetObject().ParameterBlock.GetParamByName(‘rendinput’)
    rendinput.SetValue(“C:\myvdb.#.vdb”)

Cheers!

Hey, this change has been in Phoenix and V-Ray Next for some days now, and will be in V-Ray 3’s stable nightlies tomorrow.

The available functions are:

setCoordSys
loadRenderPreset
getVelocity
getRGB
getTemperature
getSmoke
getFuel

Example usage:
$VRayVolumeGrid001.getFuel (Point3 15 15 15)

Hope this helps, please ping us if you have any issues :slight_smile:
