Is it possible to use speed as an attribute?

I’m making a car that has fake flames coming from its exhaust. The faster the car is moving, the bigger the flames.

Is there a way to make the car translation dictate the size of the flames?

As in use the previous frame’s value compared to the current? No, not without scripting

This can be done with geometry nodes:

Where did you learn this? Was there a tutorial somewhere? Geonodes are my weakness. I’ll need to know what every node does to learn how to apply it to my projects.

It’s a set of tools, you have to break the problem down into little pieces in order to understand how to solve it. It is complicated, but so is blender.

There are lots of tutorials out there, but the most important part is understanding, not knowledge. Understanding takes time, so commit to exploring the tools and you will be much better off.
