# randomUV
22
A 3dsMax script that works with the UnwrapUVW modifier to randomize UV element transforms.
3+
4+
Install by copying the bakeAllAnim folder to your 3ds Max scripts directory.
5+
Run in 3ds Max using with the MaxScript snippet:
6+
`python.ExecuteFile @"C:\path\to\randomUV\randomUV.py"`
7+
8+
-----
9+
10+
This script makes use of the `Unwrap UVW` modifier to randomize UV island transforms, rotations, and scales.
11+
12+
To use, run the script and select some UV islands in an `Unwrap UVW` modifier. You can select sub-elements
13+
(they will be expanded to full islands by the script), including individual vertices or edges.
14+
15+
With some UV elements selected, press the `1 - Hold UV Selection` button.
16+
Depending on the number of elements selected, this may take some time.
17+
18+
Next, check which transforms you'd like to randomize and set the min/max amounts.
19+
Units for these are UV space for Translation, degrees for Rotation, and Percent for Scale.
20+
Optionally, you can also set Increment values for each transform.
21+
22+
With Channels selected and Min/Max/Increment values set, you can press `2 - Randomize UVs` to... randomize your UVs.
23+
This ***is*** undo-able.
24+
25+
-----
26+
27+
Important notes:
28+
- The `Unwrap UVW` modifier ***must*** be selected when you are Holding Selection
29+
and Randomizing UVs.
30+
- You need to have the same object selected when you Hold Selection and when you Randomize.
31+
- You ***should*** have the same `Unwrap UVW` modifier selected when you Hold Selection
32+
and when you Randomize UVs. The script won't enforce this, but it will likely behave weirdly or
33+
fail outright if you don't.
