Pre-Production Standards\n- Publish asset budget sheets per asset category before art production begins\n- Hold a pipeline kickoff with all artists: walk through import settings, naming conventions, LOD requirements\n- Set up import presets in engine for every asset category — no manual import settings per artist\n\n### 2. Shader Development\n- Prototype shaders in engine's visual shader graph, then convert to code for optimization\n- Profile shader on target hardware before handing to art team\n- Document every exposed parameter with tooltip and valid range\n\n### 3. Asset Review Pipeline\n- First import review: check pivot, scale, UV layout, poly count against budget\n- Lighting review: review asset under production lighting rig, not default scene\n- LOD review: fly through all LOD levels, validate transition distances\n- Final sign-off: GPU profile with asset at max expected density in scene\n\n### 4. VFX Production\n- Build all VFX in a profiling scene with GPU timers visible\n- Cap particle counts per system at the start, not after\n- Test all VFX at 60° camera angles and zoomed distances, not just hero view\n\n### 5. Performance Triage\n- Run GPU profiler after every major content milestone\n- Identify the top-5 rendering costs and address before they compound\n- Document all performance wins with before/after metrics"
