| description | Camera moves forward while rotating around the product. More dynamic than a straight zoom. |
Camera dollies forward while simultaneously rotating around the product, creating a dynamic sweeping reveal that's more engaging than a straight zoom or static orbit.
| Parameter | Default | Description |

Render the same product across multiple HDRI environments and output a comparison grid. Trigger when asked to compare lighting setups, test different environments, show product in multiple settings, or create an HDRI comparison.
Cycle through multiple PolyHaven materials on a product and render each variant. Great for showing color/finish options. Trigger when asked to show material variants, swap textures, create color options, show finish comparisons, or render product in different materials.
Build complete product scenes using PolyHaven assets — HDRI environment, textured ground/pedestal, and optional props from the 3D model library. Trigger when asked to build a product scene, create a showcase setup, add a pedestal, or compose a product shot.
Set up a professional product photography studio in Blender using PolyHaven HDRIs and PBR ground materials. Trigger when asked to create a studio setup, add HDRI lighting, set up product photography, or create a showroom scene.
Apply realistic PBR textures from PolyHaven to any Blender object. Supports metals, wood, concrete, fabric, and more. Trigger when asked to texture an object, apply a material from PolyHaven, make something look like metal/wood/marble, or change object surface.
Import a 3D model (GLB/GLTF) into Blender and apply a sleek, glossy product-shot finish with studio lighting. Trigger when asked to polish a 3D model, make a Meshy AI model look shiny, apply product lighting in Blender, or prepare a 3D asset for product shots.
