With the update to 1.14 the standalone trailer tutorial video became obsolete. Anyone looking for it yesterday will probably have noticed it was removed from the site.
Today I have made a new video that is fully up to date and I have finished writing the written version as well. I am quite glad that I never finished writing it before, would have been a bit annoyed had I finished writing out the cargo aspect just to have to redo it. Either way the written tutorial is now 100% complete.
The video is still rendering but I hope to have it uploaded before 6pm GMT.
