Hypershade freezes Maya 2020 - macOS mojave

[kurt.frymire]

Hi folks,

I've got a showstopper bug that hopefully someone knows how to fix.  Maya 2020 on macOS mojave hangs whenever I try to do anything in the Hypershade.  Simply creating a new blinn shader causes Maya to freeze and consume 100% of the CPU.

I've completely wiped all preferences (removed files from ~Library/Preferences etc.), created a brand new scene after a fresh system reboot and even in a blank scene, creating any node in the hypershade freezes Maya.  I've even completely wiped my machine and reinstalled everything from scratch (including an entirely new home folder).  Still crashes.

My system is a 2018 Macbook Pro w/ 16GB RAM, 1TB SSD 2.2GHz i7 with Radeon RX 590 eGPU.

This issue occurs also when the eGPU is disconnected.  Anyone have ideas for how to fix?

I've attached a video to demo what's happening.

I am able to repro on my side. Will check to see if this is known/catalogued in our backlog already.

[syracoj · Accepted solution]

Okay, so we do have this logged in our bug catalogue. It's ticket# MAYA-101485 You can refer to this number in future Maya release notes to see if it has been fixed. In the meantime you may just need to use the hypershade as a floating window.

[kurt.frymire]

got it. thanks

[ferizsolnai]

Has it been resolved?

[kurt.frymire]

No. Still happens in Maya 2020.1 update

[syracoj]

This is still an issue. 

I took a look at MAYA-101485 and it has not been addressed.

The workaround though was to use a the standard floating hypershade rather than one that has been docked in the model panel.

I will inquire on dev to get a potential fix rolled out faster.

[ferizsolnai]

Oh I know the workaround.

I just find it curious to have to apply a workaround for a feature that has been working for 20 years. In a software that costs nearly 3 grand a year.
And we're talking about a known issue that has not been fixed for 5 months now. I'm sorry. I can't think of any legit excuse from a multi-billion dollar company.

[JoeDiValerio2378]

Blew a few hours on this exact issue myself here today. Thanks for the tip - things aren't playing well on OSX with docked windows. Hypershade in it's own window and it's good. Same hardware and troubleshooting path led me here to this answer and confirmation. Also a long time user and deciding to move to a different platform.
