If you have some trouble with the HASP drivers, check out this post HASP SRM troubleshooting in the Installation section.

Below is a list of known issues (not related to the installation) and some work around.

  • Message "DMM: time delta too big, simulation can't be done": this happens when the time difference between two frames is too big. For accuracy reasons, DMM won't simulate if that time delta is to big.[/*:m:3f796655]

  • Browsing the timeline doesn't run the simulator: to freely browse the animation, enable the DMM Cache and run once the animation to generate the cache.[/*:m:3f796655]

  • The simulation doesn't run when Maya's viewport is covered by another window: there is no workaround, the same thing happens with nCloth. Just always make sure that the viewport is always at least partially visible.[/*:m:3f796655]

  • Crash when rendering with Mental Ray and Motion Blur: Maya crashes because the plugin creates new faces when an object fractures. This seems to bother Motion Blur. The DMM Object have an option to show all the inner faces since the first frame. Enabling that option on every object that fracture will prevent the crash from occurring. To set that option, select the DmmObject node and check "Show Inner Faces" in the attribute editor. Repeat that step for every DMM Object that fracture (a global command will be available for the next version of the plugin).[/*:m:3f796655]

  • Corrupted scene file: we encountered some file corruptions when working with Maya's .mb files. At this point we can only recommend to use the .ma format, which is a text format.[/*:m:3f796655]

  • Missing faces when using splinters: when this happens, select the DmmObject node and check "Show Inner Faces".[/*:m:3f796655]

  • Animate some vertices of a DMM Object: this is not really an issue, but rather a very rough feature. See here for more information.[/*:m:3f796655]
