Unreal Engine Issues

Rendering with a singe frame custom frame range in the MRQ with temporal sampling renders 2 frames instead

Temporal samples cause more than one frame to be rendered with a custom range of 1 frame ...

Runtime Virtual Texture samples at low precision for very large volumes

When using a runtime virtual texture with a resolution of greater than 2^24 we can start to see a lack of precision in sampling when the sampling UVs get closer to 1. To see this we need to be usin ...

Raw Input plugin fails to process some negative values

Came from a UDN: [Link Removed] Proposed fix is to change `FRawInputWindows::ParseInputData` to use this logic instead: ``` ... USHORT BitSize = ValueCapsBuffer[iValue].BitSize; LONG SizeMask ...

Crash when moving map assets used as level instances

Changing the Global Time Dilation to a very small value and returning it to a large value (by either using the slomo console command or directly in BP) makes Physics simulating ragdolls fly off into space.

Changing the Global Time Dilation to a very small value and returning it to a large value (by either using the slomo console command or directly in BP - slomo sets TimeDilation) makes Physics simula ...

WPO is incorrectly generated on materials using Material Attributes as input to Landscape Layer Blend node

This comes from this UDN : [Link Removed] It occurs with this setup :  [Image Removed] , where Set Material Attributes expressions act as inputs to the Landscape Layer Blend material expression. ...

Incorrect mesh deformation when Max World Position Offset Displacement used

When Vertex Animated Texture is used to animate a mesh with World Position Offset, often the Max World Position Offset Displacement Material setting must be increased or the Bounds Scale increased, ...

Combining Layered Blend Per Bone with Cached Pose nodes can break root motion extraction

When the input to a Layered Blend Per Bone node is two instances of the same cached pose, we aren't sampling root motion correctly.  In the attached example, the weight on the root bone is 0 and Ble ...

Crash handling: Prevent reports of assertions during shutdown after an assertion

CriticalErrors in FWindowsErrorOutputDevice::Serialize (and other platforms) run some code after the error is detected rather than immediately terminating the process. Some of this other code is spe ...
