> [!abstract] Summary > **Render Geometry Settings LOP** — author **render-time geometry overrides** per prim: enable / disable displacement, set displacement bounds (radius), control subdivision dicing (micropolygons), toggle visible-in-refraction / -reflection / -shadows, ray-bounce overrides. The cleanest way to enable displacement on selected meshes without touching the source. --- # Render Geometry Settings - **Node:** `RenderGeometrySettings`. - Target the prims to act on with the **Primitives** selection. ## Common Parameters | Parameter | Purpose | |---|---| | **Displacement** | Enable / disable displacement on the targeted prims. | | **Radius** | **Displacement Bounds** — how much the renderer should pre-expand the bounding box to account for displacement. Too small = clipped silhouette. Too large = wasted memory / dicing. | | **Subdivision** | **Dicing / micropolygon length** — finer dicing = smoother displacement at higher render cost. | | **Visible in Refraction / Reflection / Shadows** | Toggle ray-visibility per category. Useful for hidden helper geo, light-blockers, etc. | | **Ray bounce overrides** | Per-prim caps on bounces — limit a noisy prim's contribution without changing global settings. | --- # Typical Use - **Enable displacement only on hero geo** without touching the source. - **Disable shadow casting** on background cards. - **Tighten dicing** on a closeup hero asset, loosen it on background scatter. - **Override visibility** for a stand-in prop that should not appear in reflections. --- # 🔗 Related - [[../SOLARIS MOC|SOLARIS MOC]]. - [[SOLARIS Mesh Edit|SOLARIS Mesh Edit]] — set the subdivision scheme (Catmull-Clark, etc.). - [[../../KARMA/Notes/KARMA Displacement|KARMA Displacement]] — Karma-side displacement tuning. - [[../../KARMA/Notes/KARMA MIPMAP|KARMA MIPMAP]] — texture optimisation that affects displacement maps too. - [[../../../../PROTOCOL/OPTIMISATION/Notes/Rendering Optimisation - Fabio Sguera|Rendering Optimisation — Fabio Sguera]].
