Kinematic Collision not working 100%
Hello, I really need your help. Great product by the way.
I have created a static particle field, and have a sphere moving through the particle field which is meant to push the particles aside. However, there is a large number of the particles that simply go through the sphere and are not affected by the physics of the collision. I need 100% collision detection and any particles in the path of the sphere to be pushed out of the way.
The effect is nearly there, so I believe I have the nodes/effects set up correctly, it’s just these sneaky particles that ruining everything.
Hi, there are several settings that affect the collision detection . Size and Speed, particles too small or too fast might get through
Setting the World scale to be larger, and having larger margin should give more stable result,
Please send us an email for further help.
This is not good enough. I’ve got to get this working, as I’m on the job now, doing particle effects. It seems to me that this should be at least the most basic requirement of a dynamic particle system, and to be honest, I’m disappointed.
I will reiterate the problem, I have a static particle field (emitter is a large box, X=800, Y=20, Z=800), with a little bit of turbulence and a subtle wind force so they move around a bit. I then have a model (transparent primitive sphere) simply moving through the particle field, pushing all the particles out of the way, to clear a path. This effect is comped onto a camera-tracked shot of a cyclist on a busy road. The cyclist is where the transparent sphere is, so the cyclist is pushing the particles (pollution, dust, smoke) out of the way.
I’ve tweaked world scale and margin, but i’m not getting the results I need.
When I look at all the complicated tutorials of crazy stuff Stardust seems to be able to do, I’m amazed that it doesn’t do something so ridiculously simple as this. Please help me, I’ve got to show them results, and i’m very close to ditching Stardust and moving to X-Particles (which I really don’t want to do).
The only way I’ve got it working is to increase the size of the particles. The problem is, they now look like a field of tennis balls, when it’s meant to look like dust.
