great qbism! I love your engine! Probably it must be called "the last of quake engines"! 

I don't think it's a tired old thread, it's alive and vibrant! 

tested it and on my Windows 10 works great! EF_ROTATE works on my demo too! 

Just a question: what is no lerp list? Is it a list of models (like torch) that doesn't have to do linear interpolation between frames?
Congrats!
