A bug was found in PNG image plugin of NetRadiant. This was affecting alpha channel stored in tRNS PNG chunk, also know as PNG cheap transparency. The PNG format has many storage options and its space-saving efficiency mainly comes from the ability optimizers have to select the storage format that saves the most file space for a given texture. Unfortunately, those various formats are rarely used because a very few if not almost none editing tools having PNG export option attempt to optimize them.
