wtf??? i put the dds files in place and all for htm and photoshop but now it wants me to use some filetype called explicet alpha dxt3 here do i get it for photoshop? thanks

OK when you open up the .dds file in photoshop say no to the question it gives you, then after you finish the skinning, then save it, and the big box comes up, save it as DTX1 only in the check boxes and the scroll down list, and leave the mip maps the way it is.
