Good day, in the editor the light does not work on the addition of a daylight, it only works after the play button.
On what type of light source are you referring here?
Thanks for demonstrating the bug. Indeed that looks not right. If you add a light or change its color you should immediately see the effect in the viewport.
Do you see any errors or warnings in the browser console? Besides, can you please share some information about your system (e.g. OS, GPU, browser)?
Do you see similar rendering issues with the three.js examples?
Maybe problem of your browser or version
Because I use this ,
there is not any problem
OS: Windows 7
Browser: Google Chrome 83.0.4103.61
Um, that is indeed strange. TBH, I have no idea why this happens
Maybe a GPU driver update helps…
I will try, at least on Windows 10 there is no such problem.
