Random UVW script

V-Ray V-Ray Common Off-topic

I’ve found a script on Scriptspot.com which should allow me to randomise a whole load of UVW mapping. However, my lack of maxscript knowledge is preventing me from editing it to work with Max2009. Could anyone help me with this?

Here’s a link to the script:

Thanks in advance.

Check the comments below that script posting, you’ll see there’s a 2009 fix and a simpler version :slight_smile:

Hi Colin.
Yes, I did notice the comment, but it is still unclear to me what I need to do. The code that I downloaded, to my eyes, seems to have the change already made, but when I run it, it seems to do nothing.

-- NRB Random UVW
-- By Antero Pedras
-- http://www.neuronblast.com
-- Version : 1.5
-- Modified on: 2001/Nov/24
-- Tested on MAX 4.2
-- Description :This is a simple script that adds to the selected objects a UVW map modifier 
-- and moves the UVW gizmo (on this case a box gizmo) randomly on each object. It's useful 
-- for example when you have many wood doors and want to give them different texture coordinates.
-- For additional documentation go to http://www.neuronblast.com
-- What's new in version  1.5 : progressbar , much faster , collapse stack option
-- To run the script just run it from the maxscript utility .

You know it’s a maxscript utility right? So after running it, you go to the utility tab, find the maxscript button, and it is listed in the dropdown menu. After copying your code, running it, and first run of the utility it seemed to work fine for me in 2009.

It appears I have been a moron.

EDIT…having said that, the sript runs, but it doesn’t seem to randomise the UVW mapping. It applies a UVW modifier to each selected object but they are all the same. Did you get this?
