[Closed] Setting All Scene Material Maps Amounts

Dec 02, 2005 1:01 am

I’m new to both 3ds max & MAXScript and I’m having trouble with creating a script to set all of the Material Map Amounts on all materials in a scene back to the default Map Amount values.

– I want to step through each Material in the scene using a loop.

– Change the Maps Amount for each material to the following:
meditMaterials[1].ambientMapAmount = 100
meditMaterials[1].diffuseMapAmount = 100
meditMaterials[1].specularMapAmount = 100
meditMaterials[1].specularLevelMapAmount = 100
meditMaterials[1].glossinessMapAmount = 100
meditMaterials[1].selfillumMapAmount = 100
meditMaterials[1].opacityMapAmount = 100
meditMaterials[1].filterMapAmount = 100
meditMaterials[1].bumpMapAmount = 30
meditMaterials[1].reflectionMapAmount = 100
meditMaterials[1].refractionMapAmount = 100
meditMaterials[1].displacementMapAmount = 100

– Save the file
max file save

– Open File Command to get the next file.
max file open

– END OF SCRIPT

What is confusing me is the meditMaterials[#] IDs. I need to change all of the materials in the scene, not just using one ID.

Thanks for any help that can be provided.

The meditMaterials is used to access the 24 materials in the Material Editor. The following code will change all standard materials in the scene:

(
	-- get all instances of 'standardmaterial' used in the scene
	-- and the material editor
	standardMats = getclassinstances standardmaterial
	
	-- reset all these materials to their standard values
	for m in standardMats do
	(
		m.ambientMapAmount = 100
		m.diffuseMapAmount = 100
		m.specularMapAmount = 100
		m.specularLevelMapAmount = 100
		m.glossinessMapAmount = 100
		m.selfillumMapAmount = 100
		m.opacityMapAmount = 100
		m.filterMapAmount = 100
		m.bumpMapAmount = 30
		m.reflectionMapAmount = 100
		m.refractionMapAmount = 100
		m.displacementMapAmount = 100
	)
	
	-- display results in listener
	format "% standard materials modified.
" standardMats.count
)

Thank You for the code. Now I have a new question.

I just noticed that the textures are not appearing in the Viewports, unless I press the “Show Texture Map in Viewport” icon for every Diffuse Map for every Material and Sub Materials.

Can I…

A.) Add a line in the 3dsmax.ini file to set that it is always on by default?
-or-
B.) Add to the current loop for all materials&sub-materials turn on the “Show Texture Map in Viewport” for Diffuse Map.

-- turn on/off diffusemap in viewport?
showDiffuse = true

-- get all instances of 'standardmaterial' used in the scene
-- and the material editor
standardMats = getclassinstances standardmaterial

-- reset all these materials to their standard values
for m in standardMats do
(
	m.ambientMapAmount = 100
	m.diffuseMapAmount = 100
	m.specularMapAmount = 100
	m.specularLevelMapAmount = 100
	m.glossinessMapAmount = 100
	m.selfillumMapAmount = 100
	m.opacityMapAmount = 100
	m.filterMapAmount = 100
	m.bumpMapAmount = 30
	m.reflectionMapAmount = 100
	m.refractionMapAmount = 100
	m.displacementMapAmount = 100
	
	-- turn on/off diffusemap in viewport
	if m.diffusemap != undefined then
		showtexturemap m m.diffusemap showDiffuse
)

-- display results in listener
format "% standard materials processed.
" standardMats.count

Change the showDiffuse variable at the top of the script to false to hide the diffusemaps in the viewports.
