Once collided, the question triggers the xpSpawn modifier which uses the collided particle position as the spawned particle position. The tolerance is the minimum distance that the particle must be from its target before the particle will snap to the object. Use the Acuteness of turn to control how quickly the particles turn to the object once influenced by the modifier. The xpCover Modifier allows you to either target an object, or cover/fill an object. For the collision to be detected, I’ve also added the xpCollision Tag to the sphere object. This determines whether the particles have collided with an object, and if so, trigger the xpSpawn modifier for the collided particle.

Notice from the screenshot above that we also have a question. It is a useful set-up if you need dust or debris on collision.

Basically we fire a whole bunch of particles towards an object, and when the particles hit the object, they spawn more particles. This set-up uses the xpCover and xpSpawn modifiers (hence the title). The credit should really go to the amazing collection of artists from around the world who are generous enough to share their knowledge and inspire us all.ĭownload the files from the button below followed by descriptions of each preset. I didn’t necessarily create all these set-ups, they may have been shared online by others. I built these files from my library of presets which I’ve been collecting ever since I started using X-Particles. This means some scenes use Fields now instead of falloff, which is a good thing. Plus, I also updated all the scene files to Cinema 4D R23 with X-Particles 4. I’ve kept the original files in the download, if my memory serves me correctly, they were created in Cinema 4D R18 with X-Particles 3.5. I thought it would be good to keep these files available as there are some great X-Particles setups and insights amongst this collection to learn from. These files are from an original post I made back in December 2016 as an Xmas Advent Calendar gift. 24 Free X-Particle project files to download and dissect, plenty of useful setups to learn from.
