Blob Domain¶

Blob Domain is volumetric box that contains all the sphere and capsule blobs. It is used to define the space in which the blobs (signed distance fields) are calculated and then meshed.
In general, it's a good idea to keep domain size and resolution as small as possible, as calculating the signed distance field is an expensive operation. However, in some cases it may be necessary to increase the resolution to achieve more accurate results.

Auto Fit Domain Size¶

Auto Fit Domain Size - This option allows the domain to automatically resize itself so that when Blobs are moved, it contains all of the blobs that are in the domain

Manually Resizing Domain¶

Manually Resizing Domain - You can manually resize domain by dragging X gizmo - placed on each side of domain

Note - When 'Auto Fit Domain Size' is enabled, your manual adjustments will be overridden by the 'auto-fit' feature. To prevent this, disable 'Auto Fit Domain Size' or use 'Lock Domain Face' feature (see below)

Locking Domain Face¶

When 'Auto Fit Domain Size' is enabled, you can prevent domain from moving in some directions by pressing little box gizmo (next to each X). Useful when:

• you do not want to draw mesh below floor,
• to limit domain calculation only to right side of character (for example when using Mirror modifier to create left side of character - way faster than calculating SDF for both sides)

Domain Face Lock - In video above I locked left side off Domain, so that only right side of character is generated. Left side can be generated using Mirror modifier
