Does the issue occur in the editor or during gameplay?
Gameplay
If it's a gameplay issue, please specify which movement system and camera type you're using (free movement vs. grid movement, third-person vs. first-person) or N/A if not applicable:
First person camera. movement doesn't matter
Briefly describe the issue you're experiencing:
Effects don't seem to pre-process in first person. You see the weather in the example below fall as a sheet as it first loads, then work normally.
Are there any errors in the in-game debug console or external console window?
None
Provide the steps necessary to reproduce the issue:
Make barebones game, first person camera
Make an effect
Load the game, you'll see the effect not preprocessing


Provide a download link to the bare bones project (strongly recommended if it's an in-game issue, since this helps significantly when attempting to reproduce it; the report will also be given more priority in this case):
