"NO ASYNC TICK" in Cascade viewport when adding a Skel Vert/Surf Location

Rendering - Cascade - Nov 7, 2019

Adding a Skel Vert/Surf Location node to a Particle Effect causes it to stop displaying particles and throws the warning "No Async Tick". Toggling Skel Vert/Surf Location off allows the Particle to ...

Divide by zero in beam update can cause editor to crash in Cascade

Rendering - Cascade - Sep 23, 2019

The licensee has traced the issue back to a divide by zero in  UParticleModuleTypeDataBeam2::Update. If the Target and Source are the same then the beams magnitude will be zero. When there is a Nois ...
