Ok, that means the texture is edited for multiplayer as in offline 2 player. Some textures would lag for some reason idk, but I wouldn't worry about that because you probably want to use textures for online. So really that means it's just the file for the offline multiplayer version of the texture. It's the same as "Castle_course.szs" So don't worry about that, if you see the regular szs file like "castle_course.szs" You're good to go. :P
+MarioPower55 I'd like to play the textures with my friends. So, I'd like to play multiplayer offline. Do that mean I use the "_d" file instead or do I use both?
Daniel Rose Yeah dude I try contacting with you on your channel page. I think I answered your question on your channel page already or it's a different problem. But thanks for the support!
