Environment

A neutral studio dome. Also what a glossy or metal finish reflects.

Ambient light

35%

Soft overall fill from every direction, on top of the three lights above.

Background

A transparent PNG keeps a soft contact shadow with nothing else in the frame, ready to drop onto any page.

Surface

Nothing under the model but its own shadow.

Output

Aspect ratio

The bordered window in the preview is what gets exported - everything darkened outside it is cut off, including a shadow that runs past it.

Resolution

Longest edge of the image; the other edge follows the aspect ratio above.

Drop an STL to light it.

What you get

A studio-lit photo of your own model: three adjustable lights (key, fill and rim), a real camera lens, and a material you control, rendered as a clean PNG. Export it instantly from the browser, with a transparent background if you want one.

How it works

Upload an STL, OBJ, 3MF or GLB (or load an example).
Pick a lighting preset to start, then fine-tune the key/fill/rim lights, ambient level and background.
Set the camera angle, the material colour and finish, and the output resolution.
Export. The quick export saves a PNG straight from the preview in under a second.

Common problems

The transparent export looks washed out or has no shadow

Turn Ambient light down and Key intensity up for more contrast, or increase Key softness for a bigger, more visible contact shadow.

The model looks dark or flat

Raise the Key light's intensity, or lower its elevation slightly so it rakes across the surface instead of pointing straight down. A Fill light above about 80% also tends to flatten the shading - most presets keep it well under the key.
