massive volcanic mountain 3d model

Create one massive tropical volcanic mountain as a single cohesive 3D asset for an open-world game. Huge imposing silhouette, tall central cone, large summit crater, steep rugged cliffs, deep erosion channels and sharp rock formations. Add several natural lava channels running down the slopes. The lower mountain has connected rocky tropical terrain and plateaus. Designed to be scaled to several kilometers in Unreal Engine. Prioritize large geological forms and a strong distant silhouette while remaining believable from first-person ground level. Realistic dark volcanic rock, subtle tropical vegetation on lower slopes, exposed rock near the summit. Game-ready, realistic PBR, optimized geometry, one connected asset, no buildings, characters, ocean or separate objects.
