glowing rune stone 3d model

Create a simple medium-sized stone for a Roblox game lobby. The stone should be low-detail, stylized, with smooth shapes and minimal polygons. Add a few glowing cracks on the surface. Inside the stone, show the four sealed elements using simple Roblox-like effects: • Fire — soft orange glow • Air — light blue swirl • Earth — small green crystal glow • Lightning — simple yellow spark effect The interior effects should be subtle and not too detailed. Place the stone on a basic round platform. No background, no environment, no other objects. Style: Roblox, simple, optimized, low-poly, game-ready.
