Asking for a Maxwell Layered Material in the hypershade, or asking for a new hypershade window using the new button at the top of the screen are great ways to instantly crash Maya.

I've crashed maybe 8 times tonight just trying to get a hypershade window or trying to get a Maxwell material.

Which version of Maya are you using? Please send me the crash dump, as explained here: http://support.nextlimit.com/display/ma ... g+Problems.

Could you provide step-by-step instructions what you did?

Clicking on new Maxwell Layered Material in Hypershade didn't crash Maya here.

- Windows 7 x64
- Maya 2015 SP6 + Maxwell 3.1.12 plugin
- Maya 2016 SP1 + Maxwell 3.1.12 plugin

Scene is very simple and in each case I either touched the new hypershade button or I tried to create a Maxwell shader in the hypershade.

Often this crashing occurs during a period after a render has been launched from the plugin, viewed, and then discarded. It does not seem to happen in the period immediately after opening the scene. It is also not a scene-specific problem.

I sent some dmp files via dropbox link through customer gateway

I have had this effect with various plugin versions, Maya versions, and Maxwell versions, but at the moment I am up to date with the latest from the betas and Maya is 2016 SP1

Started a new scene

Loaded the Maxwell plugin.

Mapped an image onto a plane

Switched the renderer from Maya to Maxwell

Instant crash.

I am getting crashes as well, but with different steps. (I tried to follow your steps but it did not crash)

1. Open a new scene
2. Create > Polygon Primitives > Plane
3. Assign new material... > Maxwell Layered Material
4. Display Hypershade Window
5. In Hypershade window select "maxwellLayeredMaterial1"
6. In Hypershade window select a menu item: Edit > Duplicate > Shading Network
7. Close Hypershade window
8. Select pPlane1
9. Go to Attribute editor
10. Switch to maxwellLayeredMaterial1 tab
11. CRASH

Mac OS X 10.10.4, Maya 2016 SP1, Maxwell plugin 3.1.12.

P.S. A friend of mine have tested these steps on Windows 8.1, Maya 2016 SP 1 64 bit, Maxwell plugin 3.1.12 and got a crash too.

[jfrancis]

My steps are not reliably repeatable but something simple usually involving using the hyper shade will crash Maya before too long.

Nvidia quadro fx 3800, by the way

Can you try my steps?

[jfrancis]

I'll try tonight when I get home.

After following Andrey's guide, Maya 2016 SP1 crashed here.
Looks like 2015 SP6 doesn't have this problem.

I also crash as above.

Of interest (and unrelated to Maxwell)...

"fixed by SP1"

MAYA-52657 mental ray, if selected as the renderer in the Hypershade Material View, will crash the given scene if file nodes use UV-tiling

Well, I guess I should stop using the plugin.

Or maybe see if I can roll back to Maya 2015.

Hi,

The layers tree control was implemented under the assumption that only one instance will be present at any given time. Maya 2016 adds an attribute editor panel inside Hypershade, so this assumption no longer holds. I've reorganized the code when I added support for 2016 to handle multiple instances, but I missed some cases, hence this crash. I've fixed the bug now on Windows and I will try to publish a new beta build tomorrow, after I get the OSX and Linux versions to work too.
