Description

Emitter Initial Location (EIL)module will cause the emitter with the module to follow whatever other emitter is set. If the emitter being followed has an Orbit module, the first emitter does not follow as expected.

Steps to Reproduce
  1. Create project with starter content
  2. Open P_Sparks
  3. Click the checkbox below the name "Sparks" to disable the emitter
  4. Right click to add Location>Emitter Initial Location to Smoke emitter
  5. Set Emitter Name to "Spark burst"
  6. Right click to add Location>Initial Location to Spark burst emitter
  7. Expand Start Location > Distribution
  8. Set Max (Z) to 500
  9. Add Orbit module to Spark burst

Result:
After step 8, the Smoke will move vertically with the Spark burst. After adding Orbit in step 9, the spark burst jumps around but the smoke does not follow

Expected:
Smoke spawns at the location of the Spark burst as it orbits
