Scale location-cylinder in particle system?

Hi,

I spawn particle via the location-cylinder and wonder if it’s possible to NOT ONLY scale the height of the cylinder-shape (by setting the start-height) but if it’s somehow possible to define the X/Y-radius of the cylinder to get an egg-shaped emitter-area (like in the image below)?

Thanks,
Simon

Hello Ilegacy,

I think you can only adjust the overall radius of the cylinder location node, but what you could do, is also add an Initial location node, and add an additional offset on the X (or Y) axis, this way it first takes the location of the cylinder, and then adds the additional location from the initial location node.

that way you would get a more capsule-esque area the particles will spawn in.

I tried to add the location module and added to min/max X for example 200 but this only moved the whole cylinder 200 units to the left but didn’t squash it. :frowning:

Try keeping the minus at zero, and the max at 200.
This will result in them spawning anywhere between the 0 and 200 location, plus the additional cylinder radius.

Unfortunately this doesn’t work for me especially not when I want to have to particles spawn only on the surface of the cylinder. The Init Location Module overwrites that “surface only” option and let the particles spawn again within the whole range - which doesn’t look like a cylinder enymore.

Does all this work for you? If yes, could you please post your settings? Maybe I’m just doing something wrong. :smiley:

I’ll try and give it an attempt tomorrow :slight_smile:

Work-Around: Set Cylinder-Node to “Surface Only” and add a new “Initial Location”-Node with “Use Extremes”. This creates a second spawn-cylinder. If you use the offset of the “Initial Location”-Node you can make them stay side by side and basically create kind of a stretched cylinder.
