very nice
stress test project is much more faster / reset scene is waaay more faster

Sadly 1.7 fails to run in my PC, which runs 1.6 with no problem.

I had execution issue with 1.6+ ‘master version’, but still couldn’t made it with official 1.7…

Messagebox shows :
Failed to initialize editor! Object reference not set to an instance of an object.

and log shows exception occurs in editor’s viewer code.

Please report this on Github Issues with log file attached (from project folder subdir Logs) so we can fix it: Issues · FlaxEngine/FlaxEngine · GitHub

Hello friends. I have been following this engine in recent weeks and I have noticed that in recent months it has had a noticeable increase in updates, despite having been in activity for more than 10 years. I am a Unreal Engine user but I am looking for something lighter. I understand that Flax is a software in a clear development process and has a lot to achieve, but what I have seen interests me quite a bit. My question is, visually and functionally is it closer to Unreal as an engine or to Unity? How would you describe it? Thanks and keep up the good work.

It seems a new feature ‘Collapse’ in Debug Log was added which is great! But I see no mention of it here? Seems traceback for Debug Logs is not working for me anymore. Was this put into an option that can be turned on or off? I do not see it in the options.
