Work-in-progress / development repo for an "OpenGFX v2". Or maybe that should be "OpenGFX director's edition", "refactored OpenGFX", or perhaps "OpenGFX extra zoom" or "OpenGFX 32bpp". Or some combination of all of them.
Partly derived directly from OpenGFX, partly redrawn or revised from my original 32bpp sources. Almost all sprites have been updated or revised.
Features far better organisation of sprites. Extensive use of automated composite sprite generation using Python of bubious quality. Drawn and coded with extra zoom levels and 32bpp in mind.
Download a release from the prebuilt grf releases and install using the instructions below.
Thease are early release previews not available in the in-game content downloader.
Requires git lfs for large file handling.
Requires a system which can run bash shell scripts, python3 with PIL, blend-modes, numpy and nmlc.
Clone the repository and run make_all.sh, it will take a long time...
The built baseset will be in baseset/, called opengfx2.tar.
The build newgrf(s) will be in newgrf/.
Install the baseset by copying opengfx2.tar into the baseset directory for your OpenTTD installation.
Install the newgrfs by copying each .grf file into the newgrf directory for your OpenTTD installation.
To set as the base graphics set, go to Game Options>(Graphics)>Base Graphics Set and select OpenGFX2.
To set OpenGFX2 settings, go to NewGRF Settings, find OpenGFX2 Settings and add to Active NewGRF files. Then, select OpenGFX2 Settings in the Active NewGRF files list and select Set parameters then adjust the settings. This is a bit of a hack, and will hopefully change in the future.
Install other NewGRFs as normal using NewGRF settings.
Image processing makes a bunch of intermediate files, particularly *_8bpp.png and things in pygen directories.
Files used by python are .png files, but those may be derived from other sources. Raw raw sprites wre variously drawn\generated in Paint.NET, Aseprite, Blender and more.
