Iray fails to use CUDA devices on macOS

I've submitted a bug report for this, but I'm reposting here so that others can benefit from knowing it's out there and my workaround. I gather from forum discussion this is Mac-specific; I don't own a Windows machine to test with.

The Bug

When attempting to render a scene containing Iray shaders with texture maps in the Glossy Roughness, Transmitted Color, or Top Coat Roughness channels, the renderer logs an error and loses the ability to render using CUDA. It fails down to CPU rendering.

CUDA driver version 7.5.30, NVIDIA web driver 346.03.15f02 on OS X 10.11.6, with DAZ Studio 4.9.2.70 Pro Edition (64bit)

The Workaround

This is a script I wrote to automatically remove those textures (very useful for large scenes; the Library is one of my favorite sets and suffers from it).

	var appName = "josOSXMatFix";
	
	searchMats();

// Loop through materials and identify
function searchMats( )
{
	var nodes = Scene.getNodeList();
	var n = nodes.length;
	startProgress( "Fixing materials for Iray on macOS", n, true, true );
	for( var i = 0; i < n; i++ )
	{
		var node = nodes[i];
		var obj = node.getObject();
		if( obj )
		{
			var nShapes = obj.getNumShapes();
			for( var j = 0; j < nShapes; j++ )
			{
				var shape = obj.getShape( j );
				var nMats = shape.getNumMaterials();
				for( k = 0; k < nMats; k++ )
				{
					var mat = shape.getMaterial( k );
					fixMat( node, mat );
				}
			}
		}
		stepProgress( 1 );	
	}
}

// Remove problem properties
function fixMat( node, mat )
{
	// We only know how to consume Iray Uber materials
	var shader = mat.getMaterialName();
	if ( shader != 'Iray Uber' && shader != 'V3D_IRayTannedWetSkins' ) {
		print( "No Iray for " + node.name + " " + mat.name + "; shader '" + shader + "'" );
		return;
	}
	removeMap( node, mat, "Glossy Roughness" );
	removeMap( node, mat, "Transmitted Color" );
	removeMap( node, mat, "Top Coat Roughness" );
}

// remove map
function removeMap( node, mat, prop )
{
	var propVal = mat.findProperty( prop );
	if ( propVal )
	{
		var mapValue = propVal.getMapValue();
		if ( mapValue )
		{
			propVal.setMap( "" );
			print( mat.name + ": removed " + prop + " map." );
		}
	}
	else
	{
		print("- no " + prop );
	}
}

    Same here. Rendering on Windows for now.

    I've seen this in some cases. Usually turning off Optix acceleration seems to fix it.

    I have two gpus. GTX 760 & GTX 960. 760 was my first and it works if it can handle specific scene in its memory. But 960 doesnt work. So i think that something's happening with maxwell drivers for mac.

    Turning off Optix doesn't seem to affect things for me. OptiX was off for the above error.

    Thanks for putting together this script! This is very useful for me! :-)
