this may be a stupid question, but I only really use blender casually and I need some help for a project. I'm doing a thing where I want to have rose petals flying around in an animation, so I'm using a particle system emitting rose petals. However, when I set the particles to fly around (I have them flying around using Brownian and the gravity set to 0), by the end of the animation, they are all flying outwards when I want them to stay within a certain boundary. I've scoured through every single option the particle tab has to offer, looked through dozens of tutorials, but none of them seem to solve the problem. I know there is a way to contain particles within an object, such as a cube, but I just haven't been able to find how. It is worth noting that I have tried emitting particles via both a plane and a cube, just to see if i could make it work both ways, however both have failed.
Just duplicate your original object and for the duplicated object:
- Remove its particle system(particle system also duplicates while duplicating an object)
- Go to Physics Properties, and click on Collision
- Select your original object and bake the particle system
- Delete the duplicated object
