MaxScript to batch render with automatic texture changes

Hi!

I have a scene with a single cube, and I need to render (and save) pictures of this scene hundreds of times, each with a different texture (diffuse bitmap) on the cube. The bitmap textures are numbered from 001.bmp to 699.bmp

So basically I need a script to automatically change the diffuse bitmap texture of a single material (Material 01), then render the scene to an image file, and repeat for all the textures.

Is it possible to write such a script? If yes, would anybody be kind enough to write it, or at least point me to a resource that might help?

Thanks in advance :)

Try this script:( global

Try this script:

(
	global rol_worwhite
	try(destroyDialog rol_worwhite)catch()
	rollout rol_worwhite "miauu"
	(
		local matDir = undefined
 
		button btn_browse "Select folder with textures"
		button btn_render "RENDER" enabled:false
 
		on btn_browse pressed do
		(
			dir = getSavePath caption:"Select folder with textures"
			if dir != undefined do
			(
				matDir = dir
				btn_browse.tooltip = matDir
				btn_render.enabled = true
			)
		)
 
		on btn_render pressed do
		(
			local curObj = selection[1]
			local matFiles = getFiles (matDir + "\\*.bmp")	--	get only BMP files
			renderSceneDialog.close()
			local originalOutPath = rendOutputFileName
			for m = 1 to matFiles.count do
			(
				curObj.material = standardMaterial  diffuseMap: (Bitmaptexture fileName:matFiles[m]) showInViewport:true
				outputPath = (getfilenamepath originalOutPath) + ( getFilenameFile(filenamefrompath originalOutPath)) + "_" + (m as string) + "_"  + (getFilenameType originalOutPath)
				rendOutputFileName =  outputPath
				rendSaveFile = true
				--	disable virtual frame buffer
				rendShowVFB = false
				max quick render
			)
		)
 
	)
	createdialog rol_worwhite
)

The RENDER button will be ebanled when you select the valid folder(in this folder you have to have the texture that you want to be added to the cube in BMP format).
Open Render Setup dialog(hotkey F10) and select the width and height of the rendered images, the output path, the base name for rendered images and so on.
Select the cube(or any other object that you want to use).
Press the RENDER button.
The script save rendered images in the folder, specified in the Render Setup Dialog.
The script will render the cub

How can I apply it to multiple objects

Hi, your solution works for single object, but I wanted to apply the same texture to multiple objects in the scene

Brilliant! Thanks!

This worked BRILLIANTLY! I loved the select folder option and simply using the number of .bmp files too. Thanks!!!
