Adding effects in three.js while using stereo-effect

First of all, thanks for the great software,
I will probably make a tutorial on how to use it in opentoonz later.

Right now I'm coding a VR app in three.js, and I am using your excellent library. I've implemented it into my game, and it seems to work pretty good. I am having a bit of trouble with changing mesh textures, when the effects are running though, but I already found a fix for that. (Using sprites seems to work, so I changed the textured meshes into sprites.)

My biggest problem lies in the fact that when I use the stereo effect of three.js the effekseer effects are only visible in just one of the two render windows. In my case the right renderwindow.


Do you have a suggestion for a fix for that problem?

Kind regards, Theun
