Documentation is available inside the pack. It shows how to get perfect, crisp details from the alphas. If you have additional questions you can contact me here or through the contact information inside the product.

What to download?
I made sure the alphas are usable in as many software packages as possible.
After purchasing you can download several zip files. If you intend to use the alphas in one of the officially supported apps (e.g. Blender) download the zip file that contains the name of the app:
Blender >>> lips_blender.zip (the obvious choice :) )
zBrush >>> lips_zbrush.zip
Substance Painter >>>  lips_SubstancePainter.zip
3dcoat >>> lips_3dcoat.zip
lips_all_file_formats.zip contains the following file formats
-32bit EXR, 32bit TIFF, 32bit TIFF Grayscale, 16bit PSD Grayscale, 16bit TIFF, 8bit JPG
Feel free to download those if you think you need them.
