I’ve been asked to report this here by the Marketplace team.
When exporting our Vulcan aircraft from MSFS 2024 with the Marketplace option selected, the zip that is created is 3x larger than if the Community option is selected. The difference seems to be in the textures, as shown in these screenshots.
Is that expected/normal behaviour? I read something about Marketplace exports using no texture compression but the .PNG.KTX2 textures in the Marketplace zip are significantly larger than even the source PNG textures.
File comparison between Community and Marketplace exports
Still seems odd that the uncompressed Marketplace package zip is significantly larger than the actual package source. For example, the Vulcan package source folder (not even zipped) is only 8.6GB, whereas the Marketplace zip is 16GB.
Also worth noting that, with packages as large as the 16GB Vulcan, the process of uploading to the MCP and validating that is very time-consuming, especially when uploading separate PC and Xbox packages.
You’re probably still saving your PNGs with some amount of lossless compression right? If the ktx2 is being saved with no compression it would be much larger. ktx2, like dds is lossy. So anything saved in that format would have to be saved with no compression to retain the detail of the original PNG. Just a thought.
