>>1800361Ah that's because it's loaded into the ram as that file name. So if you update the image file it won't be updated in the editor. Say you edit body3.tga on the desktop and drop it into the model's folder, if you try and load the body3.tga it'll load the unedited image. However restarting the program or giving it a different file name will make the image file update on the viewer.
Anyways do this, only check the toumei and press the orange box on the bottom. Click the PMXview window and press ctrl+A. If this doesn't show up like this then it was never there to begin with. If it is there then restart the program and use the tga regardless of 3 or 4 and it should work.
