Welcome to GTA5-Mods.com

@sisqog Only for MP Male.

@tryspartanhack1337 I'm not sure. I haven't tested it online yet.

@LRNSR Just rename both files to a free clothing slot. For example:

jbib_000_u.ydd → jbib_001_u.ydd
jbib_diff_000_a_uni.ytd → jbib_diff_001_a_uni.ytd

Do the same for every additional jersey (002, 003, etc.), or use any other clothing slot that you don't use.

@LRNSR All jerseys are based on the same model, but each one has a different UV layout. Because of that, every jersey requires its own .ydd and its own normal map. The Brazil and Argentina jerseys have different details (crest, badges, stitching, etc.), so they cannot share the same normal map. The .ydd file size has nothing to do with it.

@LRNSR These are replacement mods by design. If you want to use multiple jerseys, just rename the .ydd and .ytd files and replace a different clothing item. Everyone's clothing setup is different, so other slots may already be occupied. That's why using the default replacement slot is common practice.

@XBMarshall
Maybe in the future.

@LRNSR I'm actually using the same default MP Male shirt model for all of them. My work is focused on creating the texture and normal map. I may create a higher-quality custom shirt model to replace the default one in the future.

@Devilidan Try searching for the files in all game archives and replace them. Make sure to back up the original game files before replacing anything!
