Lm Studio Gobos & Volumetrics is a Blender add-on from Mr. Steve 3D that combines professional lighting setups, procedural volumetrics, and automated custom gobo node generation. It works with Blender 4.3 through 5.1 on Windows, macOS, and Linux, and its tools live in the 3D Viewport Properties Panel opened with the N key.
On the lighting side, it projects black-and-white shadow masks or switches to full-color image gobos mapped via emission, spawns a one-click Key, Fill, and Rim rig tracked to your active subject, and includes real-world calibration through Blackbody Temperature targets and unlinked Emission Strength multipliers. A 180-degree Z-Axis pipeline keeps texture projections oriented correctly.
For atmosphere, one-click world volumetrics fill the scene with dense fog via a slider, while localized object volumes wrap around any active object. Cinematic color presets and instanced noise algorithms shape the result, and non-destructive reverts reset atmospheric rigs without breaking existing shader pipelines. A custom Icon Gallery imports your own gobo libraries.
