Script to batch import Bitmaps and create material?

[Anonymous]

Hi,

I have 200 bitmaps (.gif) I need to import each as its own material.  

Does anyone have a batch script to do this?

I'd like the script to loop over the files in my directory and:
- create a standard material 

- assign the gif (i.e. Wall-stone.gif) to the diffuse slot

- name the material with the gif filename i.e Wall-stone

A bonus would be if you also had a script to batch apply materials to objects i.e. I select a number of objects in my view then the script:

- loops over the objects and gets the object name i.e. Wall-stone, Wall-timber etc

- finds the material of the same name

- assigns the material to the object i.e. Wall-stone material to Wall-stone object

- 'Show shaded material in viewport' for all

I'm on Max 2016

thanks

Hi there, is something like this what you're looking for?

-- load gifs and create standard materials

fn load_gifs_make_materials dir = (
	files = getFiles dir
	for file in files do (
		bm = openBitMap file
		bmt = bitmapTexture()
		bmt.bitmap = bm		
		sm = StandardMaterial()	
		sm.diffuseMap = bmt
		filename = filenameFromPath file
		sm.name = filename		
		f = "'" + filename + "'"
		print f
		for n in $*f do (
			print n
			n.material = sm
			showTextureMap n.material on
		)
	)
	
)

load_gifs_make_materials @"C:[mypath]\*.gif"

Cheers @drew.avis thanks for responding so quickly 

The script nearly works, just need a few tweaks, would you be able to:

• Strip the ".gif" from filename? As otherwise I'd need to name my objects "[object_name].gif" for the script to work i.e. mybox.gif rather than mybox
• Put an If..Then inside the second loop to check the selected object name against the filename? Because atm its assigning the last gif in the directory as the material to all the objects in the selection.

I tried to do these but I'm a novice and I couldn't get it to work 

Lastly why don't the new materials appear in the Material Editor? Is it possible to have them displayed there in a 10 x 10 grid?

thanks

Hi there, I tweaked the script a bit:

fn load_gifs_make_materials dir = (
	files = getFiles dir
	x = 0
	y = 0
	sme_view = sme.GetView 1 -- get first view
	for file in files do (
		bm = openBitMap file
		bmt = bitmapTexture()
		bmt.bitmap = bm		
		sm = StandardMaterial()	
		sm.diffuseMap = bmt
		filename = getFilenameFile file
		sm.name = filename	
		print filename
		n = getNodeByName filename
		print n
		n.material = sm
		showTextureMap n.material on		
		sme_view.CreateNode n.material [x,y]
		x = x + 100
		if x > 1000 then ( x = 0; y = y + 100)	
	)
	
)

load_gifs_make_materials @"c:[mypath]\*.gif"

Note that you don't need to have anything selected, the getNodeByName just finds the node with the same name and processes it.

Not sure about how the nodes will get laid out in the material editor, you can play with that bit to get it to do what you want.

@drew.avis you are an absolute legend! Thank you! 

It works flawlessly, but also taught me a ton about MaxScripting - I've now re-written the script to create objects on the fly and assign the bitmaps. Thank you so much. Awesome. 

cheers

@Anonymous Glad it helped.  Keep learning MAXScript, it creates a lot of possibilities!

Hello guys, I found this useful script but I dont know how to modify it.

So I run the script, I click on "diffuse" and select some png bitmaps.

Then I click on "masks" and I select same png bitmaps once again.

Then in Material Editor I see on sample slots that Standard Materials

are created with the same png as diffuse and opacity map.

My question is how to :

-Replace Standard material with Arnold Standard Surface material.

-Assign all png and their copies as "Base Color" and "Opacity"

to this Arnold Standard Surface material 

-Especially to the png assigned to "Opacity"  enable the:

Bitmap parameters->RGB Channel Ouput->Alpha as grey

And of course if I have 1000 pngs to convert, how

to insert them into a material library automatically?

Really thanks for any help.

Cheers.

Petros.

Hi Petros, unfortunately your question is beyond my knowledge, I’m a beginner at max coding. Sorry I couldn’t help. Hopefully someone else can answer.

This code is altered to suit vray. In order to suit Arnold please use macrorecorder to create steps for creating Arnold material from that code one can easily tweak its parameter to suit your needs. Hope this helps.

I am trying to use the original script to 

1. create standard (legacy) material with name based on texture or object name (both are the same name)
2. assign png texture to diffuse slot (texture is the same name as object name)
3. assign new material to the object
4. there are over 1000 objects in the scene, doing this manually would be horrific.

When I try and use the original script I get below error. I modified it as per below:

fn load_gifs_make_materials dir = (
files = getFiles dir
x = 0
y = 0
sme_view = sme.GetView 1 -- get first view
for file in files do (
bm = openBitMap file
bmt = bitmapTexture()
bmt.bitmap = bm
sm = StandardMaterial()
sm.diffuseMap = bmt
filename = getFilenameFile file
sm.name = filename
print filename
n = getNodeByName filename
print n
n.material = sm
showTextureMap n.material on
sme_view.CreateNode n.material [x,y]
x = x + 100
if x > 1000 then ( x = 0; y = y + 100)
)
)

load_gifs_make_materials @"D:\Temp Projects\*.png"

Hi, thanks for the script great help!
is it possible to modify to use multi-sub while changing the material name based off the filename of the texture?

[Anonymous]

Great script, works like a charm.

[redarmygameplay]

Can you make this script for physical materials.. and load textures to corresponding slots? I mean to say defuse textures to diffuse map and normal textures to normal map slot something like that.

[mdmowry]

I modified the script by @udhayprakash111 to include a few extra things like adding the materials (unlimited!) directly to the current SME view. All of them currently show up at the 0,0 point of the view - sort manually as needed. 

SCRIPT here:

Hi

I have tried to follow this bit but have no knowledge of scripting.

I am trying to do part of this. I already have my materials in a library. I have a scene full of objects with matching names to those materials in the library.

I am looking for a script which will look for a match between the objects in my scene (name) and the materials in my library (name) and if a match is found then apply those materials.

This would enable me to apply thousands of materials at one click.

Thanks.
