Render Room

Key Features
 

Shapes, or bring your own

Fifteen angular primitives and eleven rounded ones, from the material ball and mitred cube through gems, facets and extruded frames. Or upload a GLB and Render Room reads its parts: a model arriving with thirty-seven materials becomes thirty-seven things you can recolour individually. Tap any part in the preview to select it — and invisible geometry is ignored, because plenty of models ship a fully transparent ceiling or backdrop that would otherwise swallow every click.

​

Materials, and a tile studio

Solid colours, multi-stop gradients, your own images, or a seamless repeating texture you compose yourself. The tile studio gives you an interactive stage: place several images, scale them with corner pins, layer and reorder them. Anything crossing the tile's edge re-enters on the opposite side as you drag, so the repeat is seamless by construction rather than by correction. One tile stays live and re-editable at a time; commit it and it flattens to an image, with fair warning before it does.

​

Light that behaves like light

Three-point, split and wraparound rigs. Shadows take their character from the key light rather than a slider: a stronger light casts darker and crisper, a higher or more distant one softer and fainter, and the shadow colour is a desaturated complement of the light's own — so a warm key throws a subtly cool shadow, the way it does in a real room. Twenty environment maps across studio, interior, exterior and sci-fi, usable as reflections, as a backdrop, or blurred behind a sharp subject.

​

Thirteen camera moves that mean what they say

Grouped into orbit, move and zoom: turntable, half orbit and arc; truck left and right; pedestal up and down; crane; push in, pull back and dolly zoom; hyper zoom in and out.

Truck is a genuine parallel slide, not a pan — the camera and its target move together so the model glides across frame without swinging, which is the distinction most 3D tools quietly ignore. The dollies travel along the view ray, so the camera doesn't arc as it moves, and a hyper zoom lands exactly on the framing you set up rather than near it.

​

Easing with an actual opinion

Linear through ease-out and ease-in to bounce, elastic and a hard impact with camera shake, all on an adjustable strength dial. Bounce stays inside its bounds because a bouncing ball never overshoots its own resting height. Elastic and impact deliberately do overshoot and settle back, because that is precisely what makes them read as springy rather than merely smooth — so the camera position is allowed past its target while colours and material values are not.

​

Animate everything, not just the camera

Capture a start and an end, change whatever you like in between, and Render Room interpolates all of it: colour, gradient stops, lighting, shadow softness, reflections, material settings, camera position. The preview plays live in the panel through exactly the same tween the export renders, so it isn't a polite approximation of the result.

Models carrying their own baked animation play, scrub and export too — on their own, or running underneath a custom camera move, or switched off so you can hunt for a single frame to render as a still.

​

How it works

Pick a shape or upload a model. Dress it in the material editor — colour, gradient, image, or a seamless tile you build yourself. Set the lighting rig, shadow and reflection, then frame it with the camera.

For a still, press Add to document. For motion, turn on custom animation, click a camera move or capture your own start and end, choose a duration and frame rate, then add it as an MP4 or GIF with optional ping-pong looping. Undo and redo cover twenty-five steps with the usual keyboard shortcuts.

Render Room is free to use until the end of August 2026. No account, no sign-up, and nothing leaves your browser — every render happens locally on your own machine.
