Moving an InstancedStaticMesh will not move meshes collision

UE - Simulation - Physics - Apr 10, 2015

Moving an instanced static mesh will not move the collision along with the mesh. This will leave a visible mesh that players can walk through in one area and a blank space that cannot be walked thro ...

Collision outcome is different between PIE and Mobile Preview/Packaged Project.

UE - Simulation - Physics - Mar 25, 2015

When playing the user's project in editor vs Packaged, there has been different results for the enemies collision. When playing in PIE, you are able to fly through the enemies with no issues. When p ...

Incorrect restitution behavior for physical material set to 1 whereby momentum is gained during the simulation

UE - Simulation - Physics - Mar 24, 2015

Setting a restitution of 1 for a ground material and a restitution of 1 for a ball that bounces on the ground should keep the ball bouncing at the same height consecutively. Over the course of time ...

Physics object with collision box detects multiple begin/end overlap events even when specific collision channel is utilized.

UE - Simulation - Physics - Mar 23, 2015

If a blueprint has a physics object and a collision box, the box will register overlap begin/end events multiple times, even if the collision is set to only overlap with specific collision channels ...

This Blueprint will not compile and causes a crash in 4.8

UE - Simulation - Physics - Mar 18, 2015

The MiningBuilding Blueprint in this user's project will not compile. Clicking the compile button never switches it to "Good to Go", and a warning that it needs to be compiled appears at PIE. Repro ...

Line traces don't consistently trigger when colliding between landscape components

UE - Simulation - Physics - Mar 15, 2015

Landscapes do not consistently return "hit" on traces. Lots of AH posts on this topic, and votes on public tracker: [Link Removed] ...

Can't disable gravity for skeletal meshes

UE - Simulation - Physics - Mar 11, 2015

When replacing a static mesh with a skeletal mesh for bone animations, it falls to the ground. Even though gravity is disabled on the skeletal mesh. Changing the gravity scale to 0 is a work aroun ...

The collision of objects moving at high speeds seems to move in front of the object

UE - Simulation - Physics - Mar 9, 2015

The collision of objects moving at high speeds seems to move in front of the object. The faster the object is moving, the further the collision will be from the mesh. AnswerHub report: https://an ...

Setting PHYSX_MEMORY_STATS to 1 prevents the Engine from being built successfully.

UE - Simulation - Physics - Mar 9, 2015

If #define PHYSX_MEMORY_STATS 0 is set to 1, the Engine will not build successfully. The build fails with the message: error C2338: FPhysXAllocationHeader size must be less than 16 bytes. ...

Landscape Physical Material always registers default

UE - Simulation - Physics - Mar 7, 2015

Physical materials on landscapes always return DefaultPhysicalMaterial, even when the surface type is changed. ...
