How to export PNG format with alpha channel ？
Hi ,
This is not possible by default in Twinmotion. Please feel free to submit an idea in our public roadmap, here.
There is an active discussion where a user gives some tips on how to do it using some specific settings, it perhaps is what you are looking for.
