Need help replacing some maps in my scene.

Description

Hi I'm a new at using MAXScript, and I need to replace a lot of Normal Bump maps in my scene. I imported some models and they have a Multimaterial with several VrayMtl on them, and in some of those VrayMtls there is a Normal Bump map which I need to replace with a VrayNormalMap with the same Bitmap as before.

I searched the forums and someone had a similar problem (actually was the exact opposite), and I found a script that replaces VrayNormalMap with a Normal Bump map, so I tryed to tweak it to do the inverse, but I can't seem to make it work. I believe I need to specify that it is inside a multimaterial, and then a VrayMtl submaterial, but now I'm totally lost.

Any help would be really aprecciated.

This is the script I found earlier from barigazy:


try(destroydialog ::vrnRoll) catch() 
rollout vrnRoll " VrayNormalMap Convertor" width:168 height:30
(
	fn filterNMap obj = 
	(
		isKindOf obj.material VRayMtl and \
		isKindOf obj.material.texmap_bump VRayNormalMap and \
		isKindOf obj.material.texmap_bump.normal_map Bitmaptex and \
		obj.material.texmap_bump.normal_map.filename != undefined
	)	
	button btn "VrayNormalMap to NormalMap"
	on btn pressed do
	(
		if (getClassInstances VRayNormalMap).count != 0 do
		(
			local objMtlsArr = for g in geometry where filterNMap g collect g.material
			if objMtlsArr.count != 0 do
			(
				for m in objMtlsArr do
				(
					local NMap = Normal_Bump name:(m.texmap_bump.name) normal_map:(m.texmap_bump.normal_map)
					m.texmap_bump = NMap
				)
				free objMtlsArr				
			)
		)
	)	
)
createDialog vrnRoll style:#(#style_titlebar, #style_sysmenu, #style_toolwindow)

VrayLighrMtl Material to VrayMtl Material

Hello,
I would be appreciated if someone help me to make the script above to convert VrayLighrMtl Material to VrayMtl Material.

Pleaaaaase!

Would be possible change also a Gamma to 1.0?

Hi!
Its great script! Might you know there is a bug with Vray and normal bump in proxy objects. So all proxy objects has to have material with vraynormalmap, not with normalbump and this script is a solution.
I would be very pleased to have also an option to load every bitmap in converted vraynormalmap with gamma 1.0 in 3DS Max 2010 :) Pleasssss :)
Thanks

Nevermind, I found the error, a couple of materials had no bitmap assigned to the Normal Bump, thats where it crashed.

In any other case it works perfectly! Thanks again barigazy!!

Try this

try(destroydialog ::vrnRoll) catch()
rollout vrnRoll "NormalMap Convertor" width:168 height:30
(
button btn "NormalMap to VrayNormalMap"
fn getMaterial arr = for i in arr where isKindOf i VRayMtl collect i
on btn pressed do
(
for g in geometry where g.mat != undefined and (ins = getClassInstances Normal_Bump target:g.mat).count != 0 do
(
for m in ins where (isKindOf m.Normal_map Bitmaptex) do
(
NMap = VRayNormalMap name:(m.name) normal_map:(m.Normal_map)
if (arr = getMaterial (refs.dependents m.Normal_map)).count > 0 do (for n in arr do n.texmap_bump = NMap)
)
)
)
)
createDialog vrnRoll style:#(#style_titlebar, #style_sysmenu, #style_toolwindow)

Yeah, I tried that same thing, but it doesn't work. It returns a dialog that reads:


MaxScript Rollout Handler Exception

--No "map" function for undefined.

On the Listener it reads the following:


Rollout:vrnRoll
true
-- Error occurred in getMaterial(); filename: ; position: 213; line: 5
--  Frame:
--   arr: undefined
--   called in m loop; filename: ; position: 554; line: 14
--  Frame:
--   arr: undefined
--   m: Map #443:Normal Bump

--   called in g loop; filename: ; position: 614; line: 15
--  Frame:

OK
Rollout:vrnRoll
true

Thanks barigazy!! but your script does the opposite of what I want, it replaces any VrayNormalMap with a Normal Bump.

I need every Normal Bump replaced with a VrayNormalMap.
