Help - a Script that will Select Objects (Geo and Spline)with NO V-Ray Mat Assigned

[JezUK]

Please can someone point me to a script that will do what I am asking in the title of this thread ?

i.e.

I want to create a toolbar button which when pressed Selects/highlights all objects and splines which have NOT got a V-Ray material assigned.

So, for example, a Standard material would also be classed as NO material for me, so that object/spline should also be included in the selection set.

OR;

A Script that can Select Objects/Shapes which have Standard Materials assigned. And another script which will select objects which have V-Ray materials assigned.

Many thanks.

Here's a really quick one which select all the objects that have VRay shaders.

(
	local arrObjs = #()
	
	for i in objects where (ClassOf i.material == VRayMtl) do append arrObjs i
	for i in objects where (ClassOf i.material == VRay2SidedMtl) do append arrObjs i
	for i in objects where (ClassOf i.material == VRayBlendMtl) do append arrObjs i
	for i in objects where (ClassOf i.material == VRayBumpMtl) do append arrObjs i
	for i in objects where (ClassOf i.material == VRayCarPaintMtl) do append arrObjs i
	for i in objects where (ClassOf i.material == VRayFastSSS2) do append arrObjs i
	for i in objects where (ClassOf i.material == VRayFlakesMtl) do append arrObjs i
	for i in objects where (ClassOf i.material == VRayGLSLMtl) do append arrObjs i
	for i in objects where (ClassOf i.material == VRayHairMtl) do append arrObjs i
	for i in objects where (ClassOf i.material == VRayMtlWrapper) do append arrObjs i
	for i in objects where (ClassOf i.material == VRayOSLMtl) do append arrObjs i
	for i in objects where (ClassOf i.material == VRayOverrideMtl) do append arrObjs i
	for i in objects where (ClassOf i.material == VRayPointParticleMtl) do append arrObjs i
	for i in objects where (ClassOf i.material == VRayScannedMtl) do append arrObjs i
	for i in objects where (ClassOf i.material == VRayScatterVolume) do append arrObjs i
	for i in objects where (ClassOf i.material == VRaySimbiontMtl) do append arrObjs i
	for i in objects where (ClassOf i.material == VRaySkinMtl) do append arrObjs i
	for i in objects where (ClassOf i.material == VRayStochasticFlakesMtl) do append arrObjs i
	for i in objects where (ClassOf i.material == VRayVectorDIsplBake) do append arrObjs i
	for i in objects where (ClassOf i.material == VRayVRMatMtl) do append arrObjs i
	
	
	select arrObjs
)

pretty usedful, did it work?

(
    local theObjs=#()
    for o in geometry where (classof o != targetObject) and (not (matchpattern ((classof o.material) as string) pattern:"VRay*")) do append theObjs o
    clearNodeSelection redraw:false
    select theObjs
)

This does.

edit: o in GEOMETRY, not objects, sorry. silly mistake.

yeah, Lele did it again thanks, mate, this will be useful for sure !

[Art48]

Yep. nice for sure

Eheh, Art, i never noticed your script until after i previewed the post, so went ahead nevertheless.
The only few differences is that i won't select anything else than geometry, so no lights, cameras, helpers or targets.
Besides having been a LOT lazier with the typing, that is

Thanks Lele, this is great.

What if I wanted the same script but instead it selects geometry (including "rendered shapes") that have NO material or NO V-RAY material assigned ?

I'm pretty sure you are NOT lazy with the typing

The script will select either: if you read the condition carefully, it says "select anything for which 'VRay' isn't found in the material class name"
So standard materials and "undefined" (no material assigned, undefined class) will get selected.

Because it works on the "geometry" superclass, anything from nurbs to splines, renderable or not, will be considered.

Just thinking out loud here, but what about objects with multisub materials?
