[Closed] Iray maxscript access?

Hi Loran,

You could try “show renderers.current” (show is short for showproperties). It will give you this:

show renderers.current
.durationInSeconds : integer
.durationPasses : integer
.durationMode : enum
.displacementView : boolean
.displacementSmoothing : boolean
.displacementEdgeLength : float
.displacementMaximum : float
.displacementSubdivisionLevel : integer
.overrideMaterialEnabled : boolean
.overrideMaterial : material
.lightBouncesLimited : boolean
.lightBouncesMaximum : integer
.imageFilterType : enum
.imageFilterWidth : float
.hardwareReport : string
.version : string

So renderers.current.overrideMaterialEnabled would get/set the Material Override.

Note: setting the value doesn’t update the renderer interface (yet).

Don’t forget that any changes to the render scene dialog need to be done with it closed or else they wont stick.

Thank you!

renderscenedialog.update() to update render dialog changes

Hey loran, I saw a guy asking for multiple gpu support and I started to take a look at your script… and ended up re-writing almost all of it I hope you don’t mind, I tagged it as v1.2. it supports up to 4 GPU’s and the user can deselect the GPU 1 (which is the system gpu) and leave only the other’s doing the work… at least that’s the theory behind it

Hope you dont mind, cheers!

Thank you Artur! I update my blog
http://loran-cg.blogspot.com/2010/10/iray-manager-maxscript.html

Thanks loran! But it seems the link still points out to version 1.1

Did you like the rewrote?

link is corrected now. Yes, I didn’t check the way you rewrote, just give a quick try to it and see it works fine
thank you again man. I think this is a usefull toolset for every Iray users

Yeah, I’m already using it in a project

iray Manager v1.3 is out! check it out at : http://dimensao3.com/al/
