Avatar does not walk up custom staircase post SU4 release

Version: 1.6.32.0

Frequency: Consistently

Severity: High

Marketplace package name: N/A

Context: Package in community folder. Within free flight mode. Used with GSX spawning object and via Simobject spawner SDK tools. Before SU4, in the walkaround mode, we had set up a collision plane that allowed the human character to walk up and down our custom staircases used in conjunction with GSX and many commercial airliners within MSFS.

Similar MSFS 2020 issue: Avatar collision too big after the Sim Update 4?

Bug description:

Currently in SU4, we now have reports that the characters do not walk up the stairs which i believe is due to the change in human character collision model, now conflicting with potential steep staircases. Whilst external simobject characters are not affected, this causes conflicts for people who use walkaround mode to access certain parts of the aircraft to conduct checklists and remove certain covers before flight.

I have attempted to alter the collision shape by increasing the width of the staircase plane which did not work. In further testing, i extended the length of the staircase plane which ultimately reduced the angle the character required to walk on. However this solution is not viable as the extended length is far greater than what has been modelled.

Repro steps:

Install package, utilise staircases via simobject spawner or via external addons like GSX to spawn the model. Enter walkaround mode and attempt to walk up the staircase. (Character will not walk up the steps)

Attachments:

I have attached photos of the blender screenshots that show the collision plane and material ticked options. For the simulator photos, i have showed where i am stopped in the walkaround mode to the staircase and the last photo showing the collision shape using the sim SDK tools to show the extension of the plane on the x-axis does not work.

I hope this issue can be resolved to not only prevent issues for my product, but also for the many others that utilise such feature to walk around airport interiors, since this seems like a major show stopper for people who appreciate highly detailed interiors.

We’ve seen this issue on our scenes as well since SU4.

Hello @Bazingabill

This seems to be a duplicate of this topic: Avatar collision too big after the Sim Update 4?

Any chance you could send us your SimObject (with the blender source) ?

Hi, @Bazingabill
We successfully did this. You have to close the collision mesh rather than rely on flat mesh planes.
Think of a box mesh that’s stretch to follow the stairs. Also, drag the initial part of the stairs all the way to the ground, you can even go underground. You want your avatar to easily walk on it.

did some testing a few days ago after @Bazingabill pointed out the issue


tldr, max slope is between 30 to 40 degree
vertical steps are a no go
(hence the suggestion of @playboy to go under terrain is of course one of the keys to make the avatar climb up again)

Hi,

Thank you for the suggestion.

I have made the collision model as such with no luck in the sim, i may have done this wrong compared to what you had done. I have attached a photo in the current state.

Can you confirm if i have done this right? If its wrong an example photo would be wonderful.

Thanks,
Bill

Hi,

Did you want the files now or after the ideas from @playboy has been exhausted?

That way we can provide a file that has correlation to this thread?

Thanks,
Bill

Hi, let me see it in blender format.
I’ll get back to you. @Bazingabill
