Coming from Unity to flax, I’m enjoying seeing how much effort goes into this. It is quickly becoming my top engine and i can’t wait to see where ya’ll take it. Especially when VR is implemented.

Love to see optimizations and QOL updates.

Thank you and Keep up the good work!

Great, no need to say much！

Thank you. Nice list of fixes. Should be an easy conversion from the 1.9 series with minor adjustments.
