I’m having issues with using a Ribbon emitter in my particle System. I am using this for a trail on a missile and the issue I’m having is the trail disappearing when the missile (Particle System origin) goes off screen.
I understand this has something to do with the particle system bounds however I am having trouble finding the right setting/settings for this, the ‘set bounds’ in cascade doesnt seem to help.
Left is my bounds (the particles don’t have any velocity being applied in the emitter to give the right effect from the missile physics).
Bottom-right the missile is just off screen
and, Top-right is the desired effect.
In your particle system, click on the blank black space past your emitters and you will access the whole system settings in the details panel. Scroll down and you will see a Fixed Bounds setup which will allow you to set an exact size for you Bounds box. Remember with Ribbon effects to set a large bounds to ensure that you don’t have the problem above continue.
I think I just got this to work! In the particle system, when you press the black space to get the bounds information. Try checking on ‘Use Fixed Relative Bounding Box’ and then above that, make the ‘Fixed Relative Bounding Box’ have a huge size.
Also, in the missile actor where you have the system attached, there is a property on the emitter component called ‘Bounds Scale’ you could try put a very big number in there too. Doing both of those fixed the issue for me
