Why Does it take so long to Load a sequence In SE 5.5.xx? in LOR S5 Software Suite Posted December 26, 2020 Do you have any custom props? Like maybe a model that was imported from XLights or Boscoyo Studios? I noticed tonight on my pc that it seems the custom props I have imported take forever to load or render when a motion effect is added. It took about 5 minutes just to open a sequence before I could so anything to it.
