Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Mudbox

  • Mudbox subscriptions ending August 7, 2026 - end of sale for 3-year subscriptions, November 7, 2026 for monthly/yearly subscriptions
  • Product is being discontinued, making it unavailable for new purchases after specified dates

MoI (Moment of Inspiration)

  • It is developed by one person, so releases are years apart and there is no support organisation to escalate to when something blocks your work.
  • There is no parametric history and no assembly structure, so a late design change means remodelling rather than editing a feature.
  • It produces no dimensioned drawings or manufacturing documentation, so anything heading for production needs a second package for the paperwork.
  • Exchange is limited to surface formats such as STEP and IGES with no native interoperability with mainstream MCAD systems, so it sits at the edge of an engineering pipeline rather than inside it.
  • Each major version is a fresh purchase, and the long gaps between versions mean a fix or a feature you need can be several years away with no interim release.
