Okay i know this is probably something that can be solved easily but for some reason i keep getting these errors:
And they are somehow making me not able to spawn on a new map I'm making. The reason im getting most of those errors was probably because i accidentally munged everything.... Im guessing the one about the sky file has something to do with my MAP.sky folder, but i dont know.

MAP.Sky folder:
Could someone please take a look at this and tell me what i need to do to fix these errors?
(Especially the sky one) Thanks in advice

When you get munge errors there is no need to even play your map until they are fixed.
Use a code editor to edit these files so you can spot mistakes easier. The first 5 lines of code are duplicate, delete the first 6 lines of your sky file and save it, then clean and munge.

Your sky file should look like this: You could also safely omit the Xbox and PS2 blocks if you wanted.

Ha thanks it worked! One more question, i keep trying to insert yavin's moon into my sky file, but i dont really know how. where do i put the files so that the moon will appear?

You'd insert this into the appropriate place in your sky file: Your existing sky file would look like this: I left out the Xbox and PS2 blocks to make it easier to look at.
You would also need whatever additional files are required for this to work to be included with your project in the world1 folder.

yav_sky_planet.msh
yav_sky_planet.msh.option
sky_yavin_planet.tga
sky_yavin_planet.tga.option

Thanks again ace, that worked great too!
