Hello everybody 
I work on a game for some times now and as I install steam in it, I had check if the overlay pop in standalone game, launch from the editor (and it did ^^).
But… There’s something really wrong in the standalone version of my game :
Everythings is white except the skysphere.
My lighting is full dynamic (one sun and one skylight, that’s all ^^)
Some BP are broken too but it’s certainly another problem…
Some neofur asset doesn’t spawn (or are at the wrong place, I can’t say because I don’t see anything in all this white.
I have do so much thing in my project that I can’t tell from where the problem occurs.
I try to remove the skylight and the volumetric fog but the problem remains.
In other part of the game, I have some green meshes :
The materials seems ok but everything is covert of green light.
I don’t get why everything is fine in PIE and totally messed up in standalone.
PS : I try to build my project (windows no editor). It compiles but the game crash when I launch it. But I don’t want to annoy you with this now because it can has several causes and I didn’t check the log file yet. I may have a lot of other problems explaining this crash
EDIT : Ok, I went through the log and correct almost everything. Now, my build game starts well and the render is correct (same as in PIE). But the problem with the standalone version of my game still broken. That’s why I add the bug report tag to this question. I will try to isolate the problem and create it in an empty project but it can take time.
The thing is my game works in every possible way, except the standalone
