My idea was to use boid particles to simulate the crowd but I'm already facing several fundamental problems: What do I have to do to actually prevent my boid meshes from intersecting? … (and I've got both "Separate" and "Avoid collision" in the boid brain) - I already tried adding a force field to each particle but, while this indeed causes the particles to repel each other, repelled …

settings (also for your fire and smoke) to limit emission to that vertex group or, seeing that you seem to be using this sphere for nothing else, simply delete the parts of the mesh that should not emit particles … Quick explanation of vertex group approach: Select your mesh, go into Edit mode, then select the vertices/faces that you want to emit particles/smoke, then go to the object data tab and create a new …

First thing that comes to mind is that you need to make sure that the emitter and the collision object need to share the same layer for them to affect each other in physics simulations. From your scre …

[this is kind of an extension of How to Offset a Particle cache in Time ] I am working on a complex animation with lots of moving parts, including multiple particle systems as well as two smoke simul …

Just keep them at 0 until you need them to affect your particles, then set them to the desired values to get the party going. … If your particles have an initial velocity you need to set keyframes for that as well. …

I'm trying to create a black hair material with random streaks of gray. I came up with the following setup: At first, this appeared to work well. I was using a basic MakeHuman model, separated a sk …
