MS to resize an object's texture map

By Rokhound · 2012-10-16

Description

Hi everybody!

I'm new here and totaly new to maxscripting.

I've looked around and it seems possible but no clue how to get
it going. I'm looking for a script that will allow me to resize
the bitmap texture of a selected object.

For example a cube in scene has an 512x512 diff map assigned to
it and I would like to bring it down to 128 x 128

If anyone can steer to a right direction it would be much
appreciated.

Thank you!

Thanks! I think the problem is if I execute with the numPAD enter.

When I drag drop the script it seems to work fine.

Sure thing, will send it shortly. I'm using Max 2013.

Can you upload the test scene? Which max version?.

Thank you for the quick response Miauu

I went through it and slowly understanding scripting better.

But when I ran it I got this error from the listener:

-- Error occurred in anonymous codeblock; filename: ; position: 818; line: 28
-- Syntax error: at ), expected
-- In line: )

I can't seem to find the answer anywhere :/

Try this:

(
	local newMapSize = [128,128]
	local curObj = selection[1]
	local diffuseMapPath = curObj.material.DiffuseMap.filename
	--	slower but with better quality
	local texMap = bitmaptexture bitmap:(openBitmap diffuseMapPath)
	local theNewMap = renderMap texMap size:newMapSize filter:on
	
	/* 
	--	faster but with lower quality
	texMap = openBitmap diffuseMapPath
	theNewMap = bitmap newMapSize.x newMapSize.y
	copy texMap theNewMap
	
	*/
	
	--	show map in VFB
-- 	display theNewMap
	--	this will override the original diffuse map
	theNewMap.filename = diffuseMapPath
	save theNewMap
	close theNewMap
	freeSceneBitmaps()
	
	--	assign the resized map
	curObj.material.diffuseMap = Bitmaptexture bitmap:(openBitmap theNewMap.filename)
	showTextureMap curObj.material curObj.material.diffuseMap on
)
