cool! so should worker animations be off?
edit : just tried and all my models turned invisible, idk why. ill try again this weekend
I forgot that this version already includes the other frag light changes, so you can delete the main.js that was previously need for fragment lighting. That may be causing the issue. Can you try commenting out all the main.js code or removing the file?
worker animation can be on or off, generally on is preferred for lower main thread CPU usage.
