#X particles 4 plus
The collision is spherical, so not super accurate, but the scene is more about the question which is quite obscure, but has some nice potential, plus it also works with Sprites as well as objects. I also used some Particle Collision to stop the cars driving through each other. The turbulence is set to use only one axis, and this causes all the ‘sports cars’ to drive around erratically. The question also enables the Turbulence Modifier. Then it triggers the Color Modifier, which turns the car red. The Generated Object question checks if the car is index number 7, or in other words the 7th child. It just so happens that Car04, is a sports car… There are four types of car and seven children.
#X particles 4 generator
Here the Generator is selecting randomly from it’s children which are types of car. The question determines whether or not a particle created the object and also which specific child (index number) of the Generator you are referring to. You use this in combination with the Generator Object, and the question references the Generator Object children. This scene is about the Geometry question ‘Generated Object’. Try playing around with the iterations, reduce it by half and then cache the result to see how it influences the particle constraints. The downside is that it will slow things down, the higher the iterations, the slower the simulation. This will improve the accuracy of the constraints and also make the connections stiffer. This is because you need to increase the sub-steps, and also the number of iterations that take place on each frame. The particles constraints will probably break and not hold tightly together. If you use xpConstraints in a new scene, you will see a different result. You should also cache the particles if you wish to render over a network.

In the C4D file you can download below, it is advisable to select the xpCache and click the Build Cache button before trying to play back the simulation. This will hold the particles together, detect collisions between the particles and give them a viscous consistency. You can see from the Attribute Manager settings below that I have enabled Connection at Birth, Collisions and Viscosity. It is not a rigid constraint, more like a virtual spring. This basically creates a constraint between the particles which holds them together. This blobby action is created by using the X-Particles xpConstraints Object. It’s worth noting that to create spawning with X-Particles, you must add an additional emitter to spawn the particles from.Īs you can see, this is a fairly simple set-up, but one that introduces you to xpCover and xpSpawn, both very powerful and useful modifiers. The particles are emitted in a random spherical direction, but you can choose from various other options depending on required usage. 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.
