My name is Martin and I'm a Technical Artist (TA) from Stockholm, Sweden. I started out my career in game development as a 3D Artist in late 2010, working with game development on a wide range of different platforms (PC, Xbox 360, PS3, iOS, Android). As a Tech Artist, I work in the twilight zone between Programming and Art. Responsibilities involves things like: Tools development, Workflow improvement, Shaders, Rigging, Research, Prototyping and design as well as maintenance of new or existing pipelines.

NSUV 2.0 Free version. For non-commercial use:

NSUV Pro 2.0. For commercial use:


NOTE that Nightshade UV Editor is only compatible with Autodesk Maya 2012 and later (32/64 bit - Mac and Windows). Support for Maya 2011 and earlier has been discontinued and will not be re-implemented. Older versions of NSUV can be handed out on request though. NSUV for LT is impossible due to it’s lack of Python support.

1) Unzip the files from the zip file to your Maya user script directory. This directory is NOT the same as your installation directory. Path to this directory:
Windows: C:\Users\ %USER \Documents\maya\ %MAYA VERSION \ Mac: /users/ %USER /Library/Preferences/Autodesk/maya/ %VERSION /scripts
Make sure you copy everything! (Two folders: prefs and scripts)

2) Start up/Restart Maya and in there write the following in the command line or the script editor in order to load up NSUV: import NSUV
Make sure that you enter the command as Python!

3) A shelf button can be added to the currenyl active shelf via the NSUV menu.

4) Please note that files from an older installation of NSUV might interfere with the functionality of NSUV 2.0 - so make sure that you delete those files from the Maya user script directory prior to installing.

:: F.A.Q. ::

Q: Will NSUV interfere with other UV Editors that I use?
A: No, it shouldn't! NSUV does not modify any native files! Additionally NSUV comes with a button for quickly switching to the native editor if/when you need it.
NOTE: if your studio is using in-house scripts/tools hacked into the native Maya Editor, then you need to edit some rows in for sourcing a custom script.
More instructions are located in under the function defaultEditor().

Q: How do I flip shells vertically?
A: Right-click the Flip UV's icon. Keep in mind that many icons in NSUV have double functionality like this. Other examples are Unfold Along U/V and Normalize Along U/V.

Q: Does Nightshade UV Editor work for my version of Maya?
A: As of now, v2.0 works for all versions from 2012 to 2015 - for both 32 and 64 bit versions of Windows (tested and verified) as well as Macintosh (untested). Maya LT support is impossible because Autodesk does not think Maya LT should have Python interpreter. Older versions of NSUV (running MEL - which work for Maya LT) can be handed out on request. The last version running on MEL was 1.4.1.

Q: How do I use variables for the manipulator and texel density fields?
A: Right-click an icon to WRITE a value and left-click it to READ a stored value.

Q: How do I copy a UV Set with the integrated UV Set Editor?
A: Click and hold the button on the copy icon. A popup menu will appear.

Q: How do I do a planar projection or access the planar projection options?
A: Click and hold the button on the copy icon. A popup menu will appear.

Q: How do I rename a UV set?
A: Double-click it in the UV set list.

Q: NSUV is taking up too much screen space, how can I make it smaller?
A: The window is scalable and the frames and icon groups can all be collapsed (hidden).

Q: Where are the U and V input fields?
A: NSUV only has one general-purpose field. Use it for both U and V manipulations.

Q: Running Straighten shell doesn't work, what's wrong?
A: Make sure that you have a legal selection active, such as no edges shared by two shells. See the manual for details.

Q: Icons are missing! How do I get them back?
A: You forgot to copy the prefs -folder from the NSUV zip file.

Q: How do I reset all settings in NSUV?
Close down the NSUV window, then open up the script editor (Python tab) and execute this:

NOTE: that the window sizes and positions are not reset. Those settings are stored in a file native to Maya called windowPrefs.mel located in the Maya user script directory under the "prefs" folder!

Q: NSUV crashes during import, what is wrong?
A: You may have a broken Maya installation. Try running the row below and if that crashes Maya as well, you have a broken installation or a pirate copy:
import math

Q: My question isn't answered here, where can I send it?
A: Contact me directly via ModDB or via my portfolio.

Hey! I'm glad to hear that coz everytime -I- look at it I feel that there could be so much improvements and that the portfolio doesn't really reflect my true skill. But thanks for the comment :)

Thanks. I haven't been active here at ModDB for over like, half a year or something. Been kinda low since I've been unemployed that entire time but now things are changing for the better. I got a new job as a graphic artist now starting in a few days. :)

Thanks. Yea the company makes games for the mobile market: iPhone, iPad, android, and so on. So I get to work with something I enjoy. How are things going for you?

Reply Good karma+1 vote

Things are going well over here. A little bit of studying (Computer Science/engineering, I still don't know the correct translation) here, a little bit of attempting to make 2D Java games with 2 classmates there... :P It's all pretty enjoyable so I have nothing to complain about, except for the unmotivated and annoying 90% of my class maybe.
