When a lighting fixture is patched, sometimes the characteristics of the position motor speed dmx value are inverted in Capture. A quick solve for this is to invert the DMX value on the lighting fixture and it should go back to working fine. for example, if the mspeed is set at 0, change it's starting value to 255 or 100%.
This is only really an issue with lower end brands like Chauvet, Event lighting, Beamz, Showpro etc.
To be clear the base position motor speed dmx value for the fixture in Capture is wrong, If you plot a show on a console connected to capture, remember to update the motor speed dmx value back once you get to venue.
