Questions about Layout transition

Edit images in Timeline:

I have one region timeline which contains several images and I want to add transitions between them, such as fade out.

However, there isn’t any option for me to add/edit transition.

You need to enable transitions before you can add them to the region / widgets - https://xibo.org.uk/manual/en/layouts_transitions.html

Side note to that, transitions are only supported on Android player, Windows player due to architecture limitations will not support unfortunately.

Thanks for you answer. Is there any other way for me to make transition like slideshow?
or add some new transition besides these defaults?

You could create a video with the desired transitions perhaps?

okay, wish Xibo can add more transition effects in the future.
