Hi!
Why r88? The latest release is 100 already.

Any examples of what you’ve tried?

Here is the example with the latest version of three.js:

I’ve not used EffectComposer so the workflow becomes more obvious.

thanks very much. it works, but i have some question: does necessary have two scene and camera?

hi, I had push my test code to github, and update to version 100, I think maybe is the AdditiveBlendShader.js caused, but no idea to resolve
