Performance

Two biggest factors that influence performance, when modeling with Blobs are:

  • Domain resolution - lower is faster but gives less detail
  • Domain size - it is best to keep the size as small/close to character as possible

There is also third factor - less obvious - uniformly scaled Empties, will give better performance, than non-uniform Blobs. Use Alt+S - to unify object Scale in X,Y and Z direction (works only when Blob Fusion Workspace tool is Active)

Uniform vs non-unoform scale Left capsule tends to be slower when calculating Signed Distance Field

Fast Transform

Available from Utilities popup menu.

Fast Transform will increase performance by temporarily reducing blobs resolution, when modeling blobs

Symmetry with Mirror Mod

To reduce Domain Size the most - instead of using Symmetry Button - you can remove left half of character, and use mirror modifier. This way only half of volume is calculated.

Removing left side of character, by dragging Domain Blob object corners verts. After that and using mirror mod navigation is smoother

Symmetry Apply

Apply Symmetry allows to model non symmetrical character

Note - This operation will double the Blobs count, thus editing Blobs may become slow for complicated characters!

Symmetry

One click solution for making the character symmetrical. I would recommend using Mirror modifier though, as it is more efficient - since you cut domain size in half.

Symmetry button is located next to resolution slider
