Hello everyone,
I’m trying to make a tyre track particle. I achieved what I want using Ribbon Data; however, I want tyre tracks to disappear depending on its length not time. It looks weird when the players stops the car and tyre tracks disappear on the screen. How can I do this?
Either the question isn’t worded clearly or I’m completely not understanding. You can control the length and time, just make adjustments to size over life based on a time calculation? For example, if it takes (x) time to draw a (y) sized particle, just set the lifetime to (x).
If you are asking how to kill a particle once it hits a certain indeterminate length, a couple methods: you can spawn multiple ribbons along a path each portion with it’s own time to live. You can even alpha fade out based on life rather than just disappearing.
Another way is to use color over life (in the particle) and use the color as a variable in a material to control the visibility of the material.
I couldn’t find any settings related to length. Others are relevant to time. Imagine, a player drift his car, and there will be tyre tracks on the road. If the player don’t move his car in a specific period of time, tyre tracks disappear. I can increase the life time but it is not the solution I’m looking for. Maybe, there is no settings related to length.
You can just set the lifetime of the particle to forever and kill it via script in a blueprint (destroy component).
