Thanks for your helps your face. Yesterday I downloaded a map "Zelda" by yalt and I checked in that it have "textures/common" pics. Now it works! I can probably to see clearly and easily to do mapping.
And also I have a question. How to disable jetpack, dragoon snipes and other objects that some/all places will not suitable to use it? I was tested for disable jetpack by entities for keys and value, but it's not working.
Also your map "Cruz Beta 6" is VERY AWESOME!!! Good job your face!
