thanks for the information.
It's strange because i didn't update anything (nvidia driver or windows update) and i see the message only since 2-3 days.

I get the message : B4W WARN: Not enough varyings, disable shadows on blend objects
Any idea????

the material became 100% white, maybe it's on purpose, but quite strange.

too bad for my projet but thanks for the answer.
I will find another solution, actualy i load one JSON on button click and it at the end to modelize the object it became lot of files, so i tried to modify geometry to make it with better performance (simple objects)

Thanks btw
