If not, you have to do the old fashion way of saving your picture as a .psd file in SAI then opening it in Photoshop and save it as a .PNG there to achieve the transparent background.
THIS SOUNDS REALLY MEAN BUT PLEASE KNOW I'M NOT TECH SUPPORT!! If your pen pressure doesn't work, you can't do this or that because you're lacking a program, or something isn't updated I'm not going to help you. Don't ask me questions that can easily be answered by my tutorial or google please! I'm really impatient when it comes to people asking questions to things that are answered or lazy people that want to be hand-fed after I explained things to them. I put in a lot of effort in making a tutorial and to have that shoved aside just to be asked to put in more effort to explain things to you I've already explained is really disrespectful and irritating.
But if you are honestly confused by something in this tutorial that you can't figure out after putting in the effort to backtrack, repeat steps, and examine then please ask! I'm friendly in that regards but I'm really tired of people who want to be handheld so I won't respond to you if the answer is reasonably visible. (wow nia you're such a good, nice, patient person.)
Anyway! I got inspired by a note I got basically asking how I do my art editing! In the spirit of the holidays (and my free time) I decided to do an updated tutorial on my Photoshop editing! Hm, looking back I realize I was quite vulgar and rude in my past tutorials when explaining things. LOL oops. Well, this is all very SFW!! not a single cuss~ Leave a comment below if you want to see another type of tutorial and I will consider it~ Thank you very much for your support and I hope everyone has a fantastic holidays!
Tablet: Wacom Bamboo Fun CTE-450
