Currently is not available but maybe in the future it will available. This has already Optimized by using only one 16K Resolution on Fuselage which but other that have some texture will be used on 8K and one that have less texture is 4K. The main reason might not come from this livery that have bigger size. My loading time while using this livery is about 5 Min included 25 Scenery, 4 Aircrafts and about 90 Liveries which include this livery too. Another factor that affect the loading time is Computer Hardware like 8 GB of RAM, GTX1050, i5 CPU something that not high-end or medium can affect loading time include not update content from community. And too much of addon you have installed

Thanks For Your Comment. Anyway this livery on WIP and it going to have Hotfix Soon
