Interface
| Setting | What it does | Default | Range |
|---|---|---|---|
| UI scale | Scales the whole interface - text, buttons, panels and icons - on top of your display's own DPI scaling. Applies immediately. | 1.0 | 0.75 - 2.0 |
Undo / History
| Setting | What it does | Default | Range |
|---|---|---|---|
| Brush undo entries | How many sculpt-stroke undo steps are kept. Higher uses more memory. | 128 | 1 - 4096 |
| Graph undo depth | How many graph-editing operations (add, move, connect nodes) can be undone. | 64 | 1 - 1024 |
| Graph undo memory (GB) | Memory budget for the graph undo history; the oldest steps are dropped once this is exceeded. | 6 GB | 0.25 - 64 GB |
Landmarks
| Setting | What it does | Default | Range |
|---|---|---|---|
| Control point size | On-screen radius, in pixels, of landmark control points in the viewport. | 5.0 | 0 - 50 |
| Label font size | Font size, in pixels, of the number labels next to each landmark. | 12.0 | 1 - 64 |
| Show landmarks through the mesh | Draws landmark points, splines and labels even where the mesh covers them, as if the surface were transparent. Applies immediately. | on | - |
Turning Show landmarks through the mesh off hides landmarks on the far side of the model entirely - it is a plain on/off switch, with deliberately no fade for points that are only partly occluded.
Updates
| Setting | What it does | Default | Range |
|---|---|---|---|
| Automatically check for updates | Periodically checks for new Mesh Morpher versions in the background and shows a notification when one is available. | on | - |
| Check interval (minutes) | How often to check while the app is running. | 10 | 1 - 10080 (7 days) |
Mesh Morpher also checks once right after startup regardless of this interval.
Camera (both viewports)
These are the same values the viewport's own Camera Speed panel edits (see Camera and Display), but the spin boxes here use narrower ranges - for example Camera speed only goes down to 50 and up to 5000 here, against 1 to 100000 in the viewport panel.
| Setting | What it does | Default | Range |
|---|---|---|---|
| Orbit sensitivity | Degrees of yaw/pitch per pixel of Alt+LMB orbit drag. | 0.4 | 0.05 - 2 |
| Look sensitivity | Degrees per pixel of RMB free-look. | 0.25 | 0.05 - 2 |
| Camera speed | WASD fly / wheel-dolly speed, in world units per second. | 600 | 50 - 5000 |
| Invert pan | Off: the camera follows the mouse while panning. On: dragging grabs the canvas - content follows the mouse instead. Applies to both perspective and ortho views. | off | - |
| Focus padding (persp) | Focus (F) framing padding in perspective - higher frames the mesh looser. | 1.2 | 1 - 5 |
| Focus width (ortho) | Focus (F) ortho frame-width multiplier (x mesh radius). | 2.4 | 1 - 10 |
Masking
| Setting | What it does | Default | Range |
|---|---|---|---|
| Painted threshold | "Below this value a vertex counts as UNPAINTED everywhere - the overlay, the sculpt and deform tools, and the graph nodes. Mask values at or under it are snapped to zero as the mask is written, so faint leftovers cannot linger invisibly while still freezing the mesh. Raise it to discard more faint paint; lower it to keep softer mask edges alive." | 0.01 | 0.001 - 0.25 |
This is the one "counts as painted" threshold shared by the mask overlay, the sculpt and deform tools, and the graph's own mask-reading nodes - changing it here changes all of them at once.
Source viewport / Target viewport
The Settings window has two copies of this section, one per pane, each with the same six rows and the same defaults and ranges - only which pane they write to differs.
| Setting | What it does | Default | Range |
|---|---|---|---|
| Field of view | Camera vertical field of view, in degrees (perspective mode). | 70 | 5 - 170 |
| Exposure | Overall pane brightness; 11 is the mid-grey baseline. | 11.0 | 0 - 20 |
| Render scale | Render-resolution multiplier (supersampling); 1.0 is native. | 1.5 | 0.5 - 2 |
| Show grid | World-grid overlay in perspective mode. | on | - |
| Show floor | Studio floor mesh in perspective mode; ortho views never render it. | on | - |
| Disable shadows | Skips all dynamic shadow passes in this pane. | off | - |
These match the per-pane rows on the Camera and Display and Projection, Grid and Floor pages - this is just a second way to reach the same values.
Viewport environment (both viewports)
Unlike the section above, environment settings are shared between both panes - there is only one HDRI.
| Setting | What it does | Default | Range |
|---|---|---|---|
| Environment image (HDRI) | A status row showing the loaded file's name, or "Built-in studio" when none is set (hover it for the full path, or for the built-in image's own tooltip, "The built-in studio HDRI (Epic Quad panorama)."). The panoramic image lights the viewport and appears as its backdrop. Equirectangular (2:1) panoramas work best: .exr and .hdr keep their full dynamic range, while .png, .jpg, .bmp, .tga and .tif also load. The light globe's sky rotation keeps working on your image too. |
Built-in studio HDRI | - |
| Browse... | "Choose an image file to use as the viewport environment. Applies immediately and persists across sessions." Opens a dialog titled "Choose an environment image (HDRI)", then a progress dialog reading "Loading environment image...". The new environment applies live and is only saved once loading succeeds; on failure it shows the load error, or "Could not load the selected file as an environment image." | - | - |
| Reset | "Return to the built-in studio HDRI." Disabled when no custom image is set. | - | - |
| HDRI rotation (degrees) | "Rotate the environment (HDRI) around the vertical axis. Turns the backdrop AND its lighting together; the light globe's sky ring drives the same value." | 0 | 0 - 360 |
| Ground projection | "Project the environment onto a room-size dome instead of infinity: the panorama's floor lands on the scene floor, so the room reads at believable scale and shifts naturally as the camera moves. Only affects a loaded environment image; lighting keeps using the unprojected panorama. Looks best with 'Show floor' off." Disabled unless a custom HDRI is loaded. Turning it on triggers a re-bake behind a "Rebuilding environment projection..." progress dialog. | off | - |
| Room radius (cm) | "Dome radius of the projected room - roughly the distance from where the panorama was shot to its walls. Smaller reads more intimate and parallaxes more; larger pushes the environment away." Disabled unless a custom HDRI is loaded and Ground projection is on. | 500 | 200 - 20000 |
| Capture height (cm) | "How high above the floor the panorama was captured (tripod / eye height, typically ~160 cm). Sets where the horizon sits; raise it if the projected floor looks stretched, lower it if walls lean inward." Same enable condition as Room radius. | 160 | 10 - 500 |
In short: Browse... and Reset always work, but Ground projection only turns on once you have loaded a custom HDRI, and Room radius and Capture height only turn on once Ground projection itself is also on.
