It’s time to release the new Gorilla3D Version 1.4.0.3867! 
This update brings massive performance optimizations, stability improvements, exciting new features across physics, volume rendering and key bug fixes.

⚠️ Important Notice: Delphi Version Support Update

Starting with Version 1.4, we are deprecating support for older Delphi IDE versions. 
Going forward, we will only provide packages for Delphi 11.3 and newer. 
Please make sure your development environment is updated accordingly to enjoy the 
latest Gorilla3D features and optimizations.

🔥 What’s New in Version 1.4.0.3867?

🎯 Physics & Simulation Updates

• 🆕 JOLT Physics 5.6 Support: Updated wrapper and native Android platform support! 🤖
• 💪 Q3 Physics Stabilization: Enhanced overall stability and completely refactored constraints (BallAndSocket, Fixed, Prismatic, Hinge, Point, Gear, RackAndPinion, SwingTwist, SixDOF, …).
• 📈 Massive Performance Boost: Terrain octant-split optimization reduced step time from 25 ms down to ~3 ms!
• ⚡Physics Fixes: Resolved deep overlap explosions, overlapping mesh freezes, and fixed collision issues on small meshes (≤16 triangles).
• JOLT and Q3 now behave much more comparable to each other due to unification.

☁️ Volume Rendering & Effects

• 🆕 Smooth Volumetrics: Added dithering to fix raytracing banding in volumetric meshes.
• 🆕 Atmospheric Effects: New volumetric Smoke, Fog, and Clouds in TGorillaVolumetricNoise with fixed terracing artifacts.
• 🆕 Emissive Mapping: Now supports emissive texture mapping directly on volumetric meshes.
• 🆕 Environment Mapping: Now supports attached environment render pass and considers them in rendering

🎨 Materials, Animations & Formats

• 🆕 InPlace Animations: Added the new InPlace property to quickly switch animations to in-place mode. 🏃
• 🆕 glTF / GLB Material Variants: Implemented extension support alongside emission strength and memory leak fixes.
• 💪 Animation Stability: Fixed jittering and duplicated interpolator/joint imports on FBX models, as well as skin animation performance fixes.
• ⚡Material Optimizations: Prevented unnecessary mesh material applications during render-pass execution, saving valuable CPU/GPU overhead.

🌋 Vulkan & Viewport Improvements

• 🆕 Camera Controls: TGorillaSmoothCameraController now supports automatic target camera adjustments.
• ⚡ Adaptive UBO Buffers: Dynamic ring buffer sizing to eliminate overflow issues during CSM cascade rendering.
• ⚡ Shader & VSync Fixes: Resolved texture shearing, enabled MipMap levels, and improved VSync auto-monitor detection.

🛠️ Utilities & IDE Integration

• 🆕 SBOM Included: Added Software Bill of Materials (SBOM) to the package distribution for enhanced transparency and security.
• Audio Improvements: Added TGorillaSoundItem.LoadFromStream supporting both FMOD and OpenAL.
