Real Editor won't start

Turn off your antivirus
Check if your processor supports AVX2 instructions. You can google it or use CPU-Z.

Real Editor's package window won't show up

Changed textures won't show up in the game

Try to restore the original *.dat file in the TMM, and turn on the mod again. If you still can't see changes, most likely, you've edited the wrong texture. Tera can have multiple copies(up to 150) of the same texture. Use the bulk import feature the Create a composite mod guide to edit them all at once. Then install all moded packages to the TMM and check if it works.

Textures have black/white squares in the transparent parts after importing

Your image editor premultiplied transparency with color and overridden transparent parts of the image with a Matte color. Save your image as a non-premultiplied/unmasked image. The transparency must be stored as a separate 8-bit channel: RGB-24bit + Alpha-8bit.

Issues/Crashes with TGA/PNG export or import

Try using DDS instead. Keep in mind that to import a DDS, it must have BC1/DXT1 or BC3/DXT5 pixel format. Use BC1 for opaque textures and BC3 for transparent.
