Hitfilm 3 Pro, Windows 7, 16GB, i7 4770k 4Ghz, AMD 7950, 3GB, driver version 15.7.
I have a fractal noise texture being generated in another application and I import that file into HitFilm. An 800x800 Cineform AVI to be specific. I have a composite shot in HitFilm which has this media as one of the layers and that comp is proxied.
When I update the AVI file with changes (fresh render from other app) and then open the project in Hitfilm, it does not invalidate the proxy for the comp containing the media file and keeps using the previous proxy.
I am manually removing and re-creating the proxy to workaround this issue.
