GemRender Mod (26.2, 1.20.1) – Hundreds of Animated 3D Models

GemRender Mod draws detailed, animated 3D models for other mods. Mods that use it can show machines, vehicles, creatures, weapons, and armour. Hundreds of copies can be on screen at once, because this library mod uses GPU instancing through Flywheel.

Features:

• Skinning on the GPU: Models are kept in memory and drawn with full glTF animation channels.
• Instanced animated models: Animated models stay instanced, so many copies draw together.
• Built on Flywheel: Models get GPU frustum culling and occlusion culling for free.
• Two model formats: Bedrock .geo.json files and GLTF files (.gltf, .glb) go through the same pipeline.
• Animation blending: Adds crossfades, body-part masks, and additive layers.
• GPU particles: Each particle is uploaded once when it spawns. Decals and 3D model particles are included.
• Draws block entities, entities, and vehicles with the same system.
• Handles items, armour, and the first-person hand on the same fast path.
• Lets each copy get its own livery, camo, or team colour. Differently painted copies still draw together.
• Draws ropes, cables, and chains, such as leads, tow cables, and power lines. Every rope in view is one draw.
• Adds point lights and spot lights with shadows. Shadows work on 1.21.1 NeoForge only for now.
• Sorts transparent objects correctly against water and clouds.
• Uses KTX2 textures and BC7-compressed texture atlases to save video memory.
• Works with Iris shader packs on 1.21.1 (NeoForge and Fabric) and on 1.20.1 Fabric with Colorwheel.
• Runs on the client side only.
