translucent material give shadow only in editor or simulate mode , but none in play mode
no shadow for translucent material in play mode ? is that a bug ?
Everything is checked for the light source and the game object :
volumetric shadow, translucent shadow
The problem not happening in previous version 4.21 (we use same settings and assets)
UE 4.21 translucent material works.
UE 4.23 translucent material not working.

In case anyone sees this in the future, I found a “fix” for this.
This assumes you’re using an Actor (and not a Particle System) to place the object in the level.
Simply add an Arrow Component to your actor hierarchy (I added mine as a child to the Root) and mark “HiddenInGame” = FALSE.
You may also want to reduce the Arrow’s size so it can’t be seen.
In my case, I had a CapsuleComponent as the Root and a few StaticMesh Components as children (plus springarm / camera). One of the StaticMesh Components had a translucent material applied and all the settings properly set (e.g. Volumetric Translucent Shadows = TRUE). The shadow would always be visible in the Editor / Simulation but never when Playing. Doing the above miraculously turned the translucent shadow on during PIE.
I have no idea why this works. I was having the same issue as OP and spent nearly a whole day trying to find a solution, and then today while I was working on something totally different, I suddenly saw the translucent shadows working and figured out how I did it!
When I have more time I will dig into the code to see exactly why this is working, but hopefully this will help anyone stuck and looking for an immediate solution.
