after a short period of showing the new text.
Is there anyone good in gui here that can help maybe what i understand

Hi drog. Any errors seen on JS console… when screen turns black after text change?
Would you please try a Babylon GUI button to change text… just for testing?
Or maybe…
`scene.onReadyObservable.add(function() { setTimeout(function(){ textblock.text="ready" }, 10000) })` (or similar)
Any info gathered with those tests? thx!

thanks for support guys.
the reason i had trouble was i never called a text on creation even if just empty string
it crash if i try to instantiate Textblock.text first time after createscene i needed to
call it with an empty string in the createscene function
then after that now i can change it however i want
hope that makes sense =)
