Are your Draw Calls skyrocketing? Is your VRAM hitting the limit, causing severe stutters and texture streaming pools to overflow? Don't waste weeks manually checking every single asset in your project.

VD Optimizer is a production-grade automated scene auditing, profiling, and optimization toolkit designed specifically for Unreal Engine 5 (UE 5.1 – 5.7+). It scans your active map or entire project levels, detects critical performance bottlenecks, and resolves them instantly—saving you hundreds of hours before release.

🚀 Stop Wasting VRAM & Killing Your FPS

Every heavy static mesh, uncompressed texture, and un-culled piece of foliage drags your game’s performance down. VD Optimizer targets the two biggest performance killers in modern games: Draw Calls and VRAM Overload.

🎯 Draw Call Reduction (CPU/GPU Bound Fixes)

• Automatic HISM Clustering: Instantly scans identical static meshes placed nearby (within a customizable radius) and batches them into a single HierarchicalInstancedStaticMeshComponent (HISM) actor.

• Topological Closed-Mesh Analysis: Runs advanced edge topology checks. If a 3D mesh is watertight and solid, it disables redundant backface render passes (Two-Sided materials) automatically.

• Small Prop Shadow Stripping: Automatically turns off dynamic shadow casting on props smaller than 15 cm (pebbles, debris, small cups) to drastically reduce Virtual Shadow Map (VSM) overhead.

💾 VRAM & Texture Sanitization (Memory Fixes)

• NPOT & Resolution Management: Fixes Non-Power-of-Two textures and clamps oversized assets (>4096px) to optimize memory and enable block compression.

• Foliage & Shadow Trimming: Removes redundant shadow casting on dense grass and optimizes culling.

🛠️ Key Features & Safety:

• Automated LOD & Nanite: Batch upgrades high-poly assets or creates balanced LOD chains.

• CPU & Physics Optimization: Trims unused ticks, NavMesh bounds, and lightmap overrides.

• 100% Non-Destructive: Full Ctrl + Z undo support, automated JSON backups, and built-in protection for engine core folders.

• Complete Package: Includes pre-compiled C++ source code, Editor Utility Widget dashboard, and full documentation.
