Background Tab

Background Type#

Controls:

• Background type selector: chooses whether the room uses no environment, a generated sky, one uploaded HDR, or a six-face cube environment
• No environment: removes sky, HDR, and cube environment rendering so explicit lights and room materials define the scene
• Procedural sky: uses a generated sky with editable atmosphere controls
• HDR skybox: uses a single HDR or image-based environment
• 6-side cube: uses six separate images to build a cube environment

HDR and Cube Inputs#

Controls:

• HDR preset selector: applies a built-in HDR environment preset
• HDR upload field: uploads a custom HDR or image-based skybox
• Six-side cube uploader: uploads six images for the cube environment faces
• Visible: shows or hides the background environment
• Color: switches the background from image-based to a flat solid color
• Solid color picker: sets the exact flat background color when color mode is enabled

Available Room Images#

Controls:

• Room image thumbnail grid: reuses generated room images or texture outputs as environment inputs
• HDR button: applies the selected image in HDR-style single-image mode
• Cube button: applies the selected image as the source for all six cube faces

Procedural Sky#

Controls:

• Elevation: moves the sun angle higher or lower
• Rotation: rotates the sky around the room
• Haze: changes atmospheric turbidity and visual haze
• Scattering: changes how strongly light scatters through the atmosphere

HDR and Ground Settings#

Controls:

• Blur: softens the visible background image
• Intensity: changes how strongly the environment contributes light to the room
• Ground height: shifts the reflected ground plane vertically
• Ground radius: changes the size of the ground reflection area
• Ground scale: scales the ground reflection treatment
• Exposure: brightens or darkens the final environment exposure

Good to know:

• Use no environment for gallery-style or custom-lit rooms that should not show a sky or HDR map
• Use procedural sky when you want a controllable sky
• Use HDR or cube modes when you want an image-based environment
