A few questions on particles

How do I have my particles orbit 0,0,0 in a circle shape? I tried using the orbit node but so far all the settings I’ve tried it only wants to orbit in a blob shape in all 3 axis for some reason.

How can I spawn particles on a mesh surface without attaching them to a bone socket? Like if I wanted cloud-like particles to spawn at the locations of random vertexes on a mesh to give a tornado look to the mesh?

How do I affect the speed that a subUV index plays? I have one going but I want it to play faster.

Thanks much

You may have a velocity set to the particles, which could be affecting the orbit.
You can spawn anything at a Target Point if you place it on the map from the components tab.
To affect speed of a SubUV just increase the lifetime of the emitter and the duration of the particle.

Hello Swiss!

Im not gonna go into orbit atm, because its a bit harder to explain.

You cannot spawn particles on a mesh surface, only on a skeletal mesh its polygons or vertices.
So just import the mesh as a skeletal mesh :slight_smile:
here is a tutorial: How to spawn Particles on an Actor-Surface (Unreal Engine 4.10) - YouTube

As for the particle sub-uv, you can tweak the distribution constant curve.
if your sub-uv has a total of 32 images, set it to 32.3, if its 64 set it to 64.6.
now the lifetime controls the speed, but you can still tweak the curve a little to change speeds.
you can also use a SUBUV Movie, and this actually works on fps instead of subImage index.
Its great for looping sub-uv’s but also to have a bit more control over the speed.

Thanks. That link got me close. I can do it in the level but not in a blueprint so far. I’m planning on using it in a weapon projectile so it has to spawn the mesh and the particle system in the same blueprint. Know a work around?

I wouldnt know, try placing them both in the level, rightclick >convert to/create/add to blueprint and see if that works when placed.

I know my materials and cascade, but blueprints aint one of em.
