Test of a Blender python script that parses an xlights or Light-O-Rama (LOR) sequence file and imports the timings and intensities into a Blender animation.
That shouldn't be too difficult. The xlights format is open source and reasonably well documented. However, as I've found out, not completely documented. There are some quirks in the way the data is stored. The authors are active in the support forums and have been helpful in answering my questions that allowed me to get to this point.
