Earns its place in the superhive library for turning a repetitive task — swapping materials, pressing F12, and renaming files — into a single Render All click, while never overriding the render settings you already have.
Sloth Batch Render is a Blender add-on that automates the product variant rendering pipeline. You define your color variants and camera angles once, click Render All, and every combination renders automatically with clean, organized filenames like Red_Front.png and Blue_Front.png.
Variants can start from a color picker — choose a surface type such as Glossy Plastic, Brushed Metal, Matte, Chrome, Gold, Rubber, Fabric, Ceramic, or Wood, and the material is created for you. A one-click scan reads existing material slots to pre-fill variants, and you can edit color, roughness, and metallic values directly from the panel without opening the Shader Editor. Cameras auto-generate at standard product angles framed to your object's bounding box, and a 3-point lighting rig sizes to your product with four presets.
Before committing, you can cycle through variants live in the viewport. The batch engine respects your existing Blender render settings, renders in the background with progress shown in the N-panel, and restores the scene afterward. It supports Blender 4.0 through 5.0+, Cycles, EEVEE, and Workbench on Windows, macOS, and Linux.
Sloth Batch Render is best for rendering product visualizations across multiple color variants and camera angles in Blender, including single-object and multi-object products and imported FBX, OBJ, and GLB assets.
Sloth Batch Render is completely free to download and use.
Sloth Batch Render supports Blender 4.0 through 5.0 and later, so it runs across recent releases on Windows, macOS, and Linux. It works with single-object and multi-object products, imported meshes in FBX, OBJ, and GLB formats, and both UV-mapped and procedural materials. Before a batch starts it runs a pre-flight check for a camera, a writable output folder, and a valid variant setup, then restores the scene to its original state once rendering finishes.
Sloth Batch Render works with any render engine, including Cycles, EEVEE, and Workbench. It fully respects your Blender render settings — engine, samples, resolution, format, denoising, and compositing — which you set in Render Properties as normal, and it never overrides them. The batch renders silently in the background without disruptive windows, while progress appears in the N-panel with the current variant and angle name. When the batch is complete, the output folder opens automatically.
Sloth Batch Render can pull materials straight from imported assets. Its Scan Existing Materials option checks all material slots on your mesh in one click and pre-fills variants, which suits FBX, OBJ, and GLB imports. The One Variant Per Color mode reads every material on the object and creates one variant per material automatically, useful for simple products. You can also edit each variant's color, roughness, and metallic values directly from the panel without opening the Shader Editor, then duplicate, reorder, or enable and disable entries in the list.
Sloth Batch Render can auto-generate cameras at standard product photography angles — Front, Back, Left, Right, 3/4, Hero at 45°, and Top-Down — framed and distanced from your object's bounding box, with a configurable focal length defaulting to 85mm. You can step through angles with the ◀ / ▶ buttons and add your own manually placed cameras as named angles. Its one-click 3-point lighting rig sizes to your product and offers four presets: Studio, Dramatic, Soft, and Product Hero, placing and aiming the key, fill, and rim lights automatically.
Sloth Batch Render is listed as free here, and you can confirm current licensing terms on the developer's page. Beyond pricing, the add-on handles the full product-variant workflow: define your color variants and camera angles once, click Render All, and every combination renders with organized filenames such as Red_Front.png and Blue_Front.png. Output goes to a custom folder with an automatic fallback to the system temp folder, and a skip existing files option lets you resume interrupted batches without re-rendering finished frames.
