Unwanted particle gap while moving

[Rulkui]

Hi everyone

Ive done my simple particle system to simulate rocket trail or something similar. Ive attached it to my bullet mesh in Viewport editor and it is working but there is huge gap between bullet and particle system, size of gap is a speed dependent. Can anybody help?

Use Spawn PerUnit module instead of Spawn if you aren’t already and see if it helps.

Thank you for replay

I`ve add Spawn PerUnit module but

1. still Spawn module → distribution is affecting (also when I turn Spawnmodule off - it isn`t posibble to delete this module); Spawn PerUnit → distribution - seems not affect anything
2. adding Spawn PerUnit break my particles, change Max Frame Distance to 1 make it work again.
   After that, it looks same as before and it still got that annoying gap
   Can you say more about Spawn PerUnit module? I played with all parameters of this module but didn`t see any changes.
   Maybe should I change something in Spawn module or use different TypeData?
