'Morning, Am continuing to work on my Kai Tak GT Circuit and while I'm getting closer to what I'd like am finding the file when exported to GTR2 is huge (+300 MB). And this is before I'm ready to upload for testing. Have been looking for threads for guidance under searches for SIZE, FILE, FOLDER, PACKING, COMPRESSING, etc... Most deal with DDS files or how to pack the file once the track is complete. I'm far from complete. Any advice on what I should be doing to minimize the exported folder size now? I would guess I'm about 60% done. Still need to add background buildings, some finishing touches and a skydome. Do I have to begin not only exporting the track after each update but then compress it as well before testing? When testing with a big grid (40 cars) am finding the game becomes unstable and I get some flashing text and issues with the HUD. If I take the same cars to another track (with a track folder size of less than 50MB or less) it runs fine. Much appreciate any advice so I can get down to it this weekend. Will post a new video soon as well. Thank you.
