# LIGHTING — Knowledge MOC > [!abstract] About this MOC > Everything related to **lighting** — physical light transport theory, practical setup in Arnold, and lighting in a Solaris/USD context. Read *Theory* first if you are new, then use *Practice* as a recipe book on the job. --- ## 🧭 Reading Order for Newcomers 1. **Theory** → [[Notes/LIGHTING Theory|LIGHTING Theory]] — exposure, color temperature, inverse square law, three-point lighting. 2. **Practice in Arnold** → [[Notes/LIGHTING Arnold Practice|LIGHTING — Arnold Practice]] — lights, samples, AOVs, per-light AOV strategy. 3. **Practice in Solaris** → [[../HOUDINI/SOLARIS/DEPARTMENT/SOLARIS Lighting|SOLARIS Lighting]] — lighting within a USD / Karma pipeline. --- ## 📚 Fundamentals Evergreen concepts that apply to every renderer. - [[Notes/LIGHTING Theory|LIGHTING Theory]] — light as energy, falloff, color temperature, cinematic conventions. --- ## 🎨 Practice Renderer-specific setup. - [[Notes/LIGHTING Arnold Practice|LIGHTING — Arnold Practice]] — lights, samples, AOVs in Arnold. - [[../HOUDINI/SOLARIS/DEPARTMENT/SOLARIS Lighting|SOLARIS Lighting]] — lighting in a Solaris/USD pipeline. --- ## 🔗 Related MOCs - [[../ARNOLD/ARNOLD MOC|ARNOLD MOC]] — renderer-level detail for the Arnold side. - [[../LOOKDEV/LOOKDEV KNOWLEDGE MOC|LOOKDEV Knowledge MOC]] — the shading side that pairs with your lights. - [[../COMPOSITING/COMPOSITING MOC|COMPOSITING MOC]] — downstream reading of AOVs. - [[../KNOWLEDGE MOC|KNOWLEDGE MOC]] — top-level index.
