[Bullet] RayCast pointing at SoftBody freezes game (no scripting involved)

[dlstar89]

Godot version

3.4.3

System information

Windows 10, GLES3, Intel Iris Xe (30.0.101.1340)

Issue description

Game freezes when RayCast is pointing at a SoftBody, please pay attention to the structure of the mesh supplied to soft body, this are basically 2 planes joined in blender

Steps to reproduce

No scripting is involved
Supplied project contains scene 'scene_not_working.tscn', when you run it game should freeze, if you disable RayCast then it works fine

Minimal reproduction project

softbody_raycast_project.zip

Same issue persists in 3.4.4.stable

[Calinou]

@dlstar89 Does this occur with a single, non-disjointed plane (with 4 or 8 vertices)?

[dlstar89]

@Calinou
Just to make sure things are clear ill post 3 examples, all are single meshes and hopefully I use correct terminology

This mesh works fine, as can seen there are 8 vertices and 3 faces

This does not work, 8 vertices and 2 faces

This does not work, 8 vertices and 2 faces, connected vertices to create edge ([1,2], [3,4])

Unchecking Ray Pickable option doesn't solve the freezing issue with none working meshes

[dlstar89]

@Calinou
Just to mention, the last version it worked fine was in 3.3.4.stable

[Calinou]

@Calinou Just to mention, the last version it worked fine was in 3.3.4.stable

Can you reproduce this in any of the 3.4 betas and RCs to determine when the regression started?

[dlstar89]

@Calinou
I only tested on Windows 10 using Godot 64 bit version

BETA freeze start from: Godot_v3.4-beta6_win64
RC freeze starts from: Godot_v3.4-rc1_win64

@Calinou
The only entry which mentions SoftBody

[timothyqiu]

This behavior is introduced since Bullet is updated to 3.17: #48300

Before the update, it works fine but there are errors in the console:

ERROR: Spatial node not defined in the pinned point, this is undefined behavior for SoftBody!
   at: _update_cache_pin_points_datas (scene/3d/soft_body.cpp:770)

Looks like there are undefined behavior in the SoftBody setup.

[dlstar89]

@timothyqiu
Errors went away after providing Spatial Attachment Path, but the game still freezes with this kind of mesh

[dlstar89]

@Calinou
Is there anything else needed to get this looked at by someone else?

[Calinou]

@Calinou Is there anything else needed to get this looked at by someone else?

I don't know how to fix this myself, sorry.

[fbcosentino]

Just confirming I get this issue on 3.5.rc3, and I at least got the project to work by keeping the SoftBody mask layer to the collision layer of interest but moving the collision layer to an unused one. So softbody finds objects but objects don't find it. No longer freezes then
