Use when working with 3D-specific systems — materials, lighting, shadows, environment, global illumination, fog, LOD, occlusion culling, and decals in Godot 4.3+

This benchmark measured an earlier version of the skill.
A newer attempt on gemini-3.8-flash on 10/20/2026 did not produce a publishable comparison (not comparable). The snapshot above is the previously measured run.
One of 10 test cases the skill fixed. Same model, same prompt, with and without the skill.
After upgrading a Godot 4.6 project to 4.7, smooth metallic surfaces reflect the sky background with slightly different roughness mipmap distributions even though material roughness was untouched. Which project setting default changed in 4.7 for sky reflections, and what value restores the 4.6 look?
| Checked | Without skill | With skill |
|---|---|---|
| Identifies rendering/reflections/sky_reflections/roughness_layers as the setting that changed from 7 to 8. | Missed | Passed |

All examples target Godot 4.3+ with no deprecated APIs. GDScript is shown first, then C#.

Godot uses a right-handed coordinate system with metric units (1 unit = 1 meter):
| Axis | Direction | Color |
|---|---|---|
| X | Right | Red |
| Y | Up | Green |
| Z | Out of screen (+Z toward viewer) | Blue |
Cameras and lights point along -Z by default. When a character "faces forward," they look along -Z.
| Node | Purpose |
|---|---|
Node3D | Base transform node — position, rotation, scale |
MeshInstance3D | Displays a mesh with a material |
Camera3D | Required to render 3D — perspective or orthogonal |
DirectionalLight3D | Sun/moon — parallel rays, cheapest light |
OmniLight3D | Point light — emits in all directions |
SpotLight3D | Cone light — flashlights, spotlights |
WorldEnvironment | Sky, fog, tonemap, post-processing |
Decal | Projected texture onto surfaces |
GPUParticles3D | GPU-driven particle effects |
CSGBox3D etc. | Constructive Solid Geometry — prototyping |
GridMap | 3D tile-based level building |
Godot 4.7+:
GridMapexposes its internal octants for spatial queries (cell_octant_size,get_used_octants(),get_octants_in_bounds()and friends) so you can scope work to a region instead of walking every cell.CSGShape3Dgainsautosmooth/smoothing_anglefor automatic face smoothing.
