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 :)

Same material

Hi Miauu, this script is exactly what we'd need for few hundreds of renders. I'm having a trouble with Standard material since I'm using Corona. Is there a way to use existing material, and only change diffuse map? Thanks

Hi!
Check if this works as you want:

(
	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
				curObj.material = CoronaMtl  texmapDiffuse: (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
)

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

Replace this lines:

on btn_render pressed do
		(
			local curObj = selection[1]

with this:

on btn_render pressed do
		(
			local curObj = selection as array

How to add bump maps to it

After some struggle I figured it out that I have to do the way you specified it. How do I add bump maps path also to it.

thanks for your time

replace this:

curObj.material = standardMaterial  diffuseMap: (Bitmaptexture fileName:matFiles[m]) showInViewport:true

with this:

curObj.material = standardMaterial  diffuseMap:(Bitmaptexture fileName:matFiles[m]) bumpMap:(Bitmaptexture fileName:matFiles[m]) showInViewport:true
