The problem is you need to put mission_one_b7 and/or your map name in the shaders list in you scripts folder. Otherwise some shaders don't work right. Not sure about all the info on that but just do it. Except, DONT rely on other shaders. Anyone who does not have mission's voda texture will not be able to see it and get the ugly grey-with-white-stripes texture. Learn how to make your own shader file (very easy, trust me) with the shader manual so you can avoid this.
