Yeah @ncmako, your correct the built game IS much larger but not by a huge amount, at least for me anyway, the imageblock was usually coming in at around 18-24mb for my little project and the seperate folders when ported over come in at around 30mb-ish so its negligible in my eyes, but yeah it doesnt seem to enjoy using alttextures if you have the imageblock.bin instead of the raw image files.
What I normally do is make sure all my image files are compressed as far down as they can go, Im experimenting with the different dds compression methods but png's seem to hit around 26kb-120kb and 1024x1024 dds At around 512kb, but since I include a metric tonne of full video in my game i dont sweat the small stuff like images and with people growing accustomed to 1-4gb downloads I dont think its going to matter on the user end too much and using a compression tool to pack the game like vishnu packer, lock and launcher combined with a Click team installer, you get a nice condensed file, I mean the footprint on a built game for me at the moment is around 700mb, with the installer compressed and packed that comes down to around 250mb, so i think using imageblocks is a pretty inefficient way to go about things in the long run, it affects texture functionality adversely as far as i can tell, means I cant edit images and textures in a built game without rebuilding the whole damn thing, and just seems like something thats maybe useful but not really to me. Im sure BlackFox responded in a post I made ages back saying something along the lines of .png format and no imageblock being the best way to go? Or I may have imagined that, but its true for me anyway
smoke em if you got em
