Thanks! And is it possible for me to import preset files to my phone and make them using a drawing app?
To import the image textures, yes! But, double check things of importance:
Whether or not it has Alpha (transparency)
The file is 513 x 513 pixels
From then on, you'll need to edit the .material files using your computer.
(in case you don't know how to import the images, you can simply e-mail them to yourself or message them to a friend on Facebook! They'll be saved in the
cloud easily.)
