The map terrain that you make are looking great but the one I afraid to tell you was the crystal. The Crystal, however, is too bright and not glow on on the cave that you make. so to make your crystal much good was put a “PointLight” and also “Bloom in the Lightning section”. To reduce the Neon Color on your Crystal was put “Bloom on the lightning section” so that the cave dont get too bright.
Now let focus on the lightning on your game. the background of your picture is too dark and I prefer you use the new lightning-like Future is Bright: Phase 3 - Studio Beta So the map that you created right now cant be too dark for a player. if you wanna make good lightning on your game was make your “Outdoor Ambient to… 0,0,0 and the shadow softness you can make to Just 0.5 or 1”. anyway I hope you have a wonderful day and I will see you next time
