Hi guys,
I created a blank project with the mobile setup,
it has a shadow at the beginning,

but the shadow has gone when I switch the Preview Rendering Level to Android
so how can I get the Shadow back? thanks!

Hey there @bbcool4444! First make sure movable lighting for mobile is enabled. Then force no precomputed lighting in your world settings. Let me know if it works!

Oh that’s a bit odd that the bricks are casting shadows and the balls aren’t. Leads me to believe there might be a difference in their settings. Are the balls and the bricks sharing similar settings in their respective detail panels?
