Crash in DrawNodeInBoxMode

[svetlin.nikolov]

Hey guys,

I am getting a crash when I repeatedly call EvalWorldState() on a geometry with Skin modifier which has Display as Box. This happens only in 3ds Max 2020 and 2021.

Steps to reproduce:

1. create a sphere and a biped
2. put a Skin mod on the sphere, pick the biped
3. create a Phoenix Simulator (any Phoenix 4.x will do, you can start a trial here https://www.chaosgroup.com/trial/phoenix-fd-3ds-max)

4. make the sphere displayed as box
5. run the sim - crash:

It is an infinite recursion inside DrawNodeInBoxMode:

I have also attached a scene - just open and start the Phoenix simulation immediately.

Thank you in advance, cheers!

so you need to ask Phoenix (Chaos Group) about it

[svetlin.nikolov]

@denisT.MaxDoctor , I might not have been clear - the crash is entirely in 3ds Max's callstack. It seems to be triggered indirectly by us (Phoenix / ChaosGroup) just calling EvalWorldState() on this node, which is what has to be done for any scene node in order to interact with it. It also crashes only when it's displayed as Box.

If an Autodesk developer can reproduce it and shed some light on the problem, I would be very grateful.

Thanks in advance!

How can I reproduce the problem without Phoenix? 

[svetlin.nikolov]

Ah, have not tried yet to reproduce it without the sim. I was going to try and create a minimal plugin that calls SetTime() and EvalWorldState() repeatedly, but decided to ask here first if it's something obvious when traced with symbols.

A Phoenix trial is 30 days without any limitations and just expires in the end. You need a reg in chaosgroup.com, start the trial from here and it would forward you to the downloads - Phx installs in 10 secs and will also automatically install the CG license server.

If you are with Autodesk, please PM me and we'll get you a license ASAP - note that the software will not behave any differently though.

Cheers!

Hi @svetlin.nikolov , thanks for reporting this issue. 

We'll look into it and get in touch with you if we have questions.
