Z position to scale? or 3d flare
I’ve been following video copilot’s tutorial on smoke trails with particular and optical flares, but i have been trying to use just the built in plugins to achieve the same result. I have been pretty successful with the smoke trails themselves, but I run in to trouble with the lens flares. I tried linking the 2d flare’s scale to the null object’s z position and the x and y to the null’s x and y position. however, the z position goes from a negetive number to a positive number, and the the scale then goes in reverse. Is there a simple expression that would make the scale relative while keeping it in the same position as the null? or is there an easy, free way to create a 3d flare without using any external plugins?
I just joined so i’m not sure if this should belong in the AE expressions section, so please tell me if it should

No need to delete your post if you’ve figured out a work-around — but posting your solution might help people who find this thread in a search later.
Good luck with your project.

the work-around was to simply have a small particle system with a low velocity following the null, then apply a tint and glow effect. making the particle “explosive” made a pretty good bright light/lens flare
