Description

When an Arrow Component is added to a blueprint and made visible in Game, a GPU Particles collision will fail until the arrow component is outside the Camera Frustum or turned back to hidden in game. It does not matter if the arrow is in a different or same BP as the Particle effect, any arrow component will stop all GPU Collision from occurring.

Steps to Reproduce
  1. Open the Attached AH_GPUCollision 4.9 Test Project
  2. PIE
  3. Move the Camera to frame the Particle system without the arrow component in the Camera's view

RESULTS: Collision starts when Arrow leaves view

EXPECTED: The Arrow should have no impact on the Particles' Collision.
