Click, double-click, ⌘-click.

Three clicks, three jobs

Every tile on the RoomGen Studio canvas - a room, a render, an AI sheet, a clip - answers to the same three gestures:

Selection is what arms the side panel: the Designer library presets all act on the current selection, and they stay greyed out until something is selected. Room tiles carry a reminder of this as a tooltip on hover, but a tooltip is easy to miss - and a single click that quietly selects instead of opening looks a lot like a click that did nothing.

Selecting versus opening

The distinction is worth internalising, because it decides which half of the studio you are talking to.

Select when you want to act on something: select a room and the Designer library's Room tab lights up with camera angles; select a finished render and the Render tab offers design tools like Golden hour or Declutter. The card tells you what it will cost before you press Apply.

Open when you want to look at something: double-clicking a room shows every render it has produced, and double-clicking a render opens the render studio, where angle, lighting, mode and sample count live along with that image's history.

References: showing instead of describing

Ctrl/⌘-click is the least obvious of the three, because nothing on the tile advertises it. It marks an image as a reference, and references are passed to the model as visual input alongside your instruction.

That matters because some things are far easier to show than to write. "Use this sofa", "match this lighting", "keep this material palette" are all hard to put into a sentence precisely enough, and trivial to point at.

A marked tile is outlined in terracotta, so you can see at a glance what is armed. The gesture is a toggle: Ctrl/⌘-click it again to un-mark it. You can mark several images before generating, either one at a time or by dragging a selection box around them - useful when you want a whole set of renders to inform the next one.

Moving and deleting

Tiles are dragged to move them. The studio separates a click from a drag by how far the pointer travels, so a slight wobble while clicking still counts as a click - you will not knock a tile out of place by accident.

To remove something, select it and press Delete, or use the Delete button in the toolbar on the right of the canvas. That button stays disabled until something is selected, which is the same selection rule as everything else here.

If a tile you are hunting for is not on screen at all, that is a different problem - panning and zooming covers it. And if you have not made a render yet, start with your first render.
