Hi, I'm facing the same issue. Have you made it to transparent yet? @jiciqiang

Hi @jiciqiang @congthinh , I changed the source code and build a transparent version of Gio.js, the build file can be found here.

The screen shot shows the final effect.

Hi, thanks for the update. I tried new build but still remain background, any setting in configs variable need to be changed? Thank you.

It works great. Thanks a lot.
P/S: I was thinking of adding alpha in WebGLRenderer from THREE.js lib and you have made it work so well.

Hi @congthinh , I add a setTransparentBackground API to giojs which can be used to make background transparent and draft a new release 2.1.0. This version also update the example and add some docs for this feature.

As previous gio.transparent.min.js 's moving particle's color isn't precise, this version solved it.
