I am having problems trying to get these particles to display like your demo.
For example, as you see in the attached screen shots, I have put the files in the correct directories and updated the custom.scss file. but as you can see by the results I get, I am not able to get my output to look like yours.

Any idea what I am doing here. After compiling the css for the outline, the results remain the same. Even if I choose a different style in the particle, there is only a minor change and still nothing like your demo.

Thanks for looking into this
