In this guide we will explore how we can create a digital art in 3D and put it in the 3DS Camera app. Requirements A 3DS/2DS (duh) An SD Card A computer Layer painting programs or whatever (Mine being Photoshop) MPO 3D Creator Part 1 - Preparing your photo slot You can't just "add" a picture to your 3DS gallery, we have to create a slot for it THEN replace it. Launch your 3DS Camera app. Take a picture, anything really. Put the SD Card in your computer Under your SD:/DCIM/xxxNINxx/ you should see 2 files: HNI_xxxx.JPG HNI_xxxx.MPO This is the very photo you took, JPG file being the 2D and MPO file being 3D. Part 2 - Preparing your images Here we don't only make a 2D image but we have to create a 3D one as well, I'll use my recent art as an example. This is the image I will be using (just recently made it): While you are painting or drawing, make sure you split your image into different layers, I have the total of 3. First being the background layer. Warning: Spoilers inside! Second being the body. Warning: Spoilers inside! Third and top being the arm-hand and the axe. Warning: Spoilers inside! ___________________________________________________________________ Save your creation like you normally would and you have your 2D image, rename it to HNI_xxxx.JPG and replace the photo in your SD Card. Preparing for 3D: We will need 2 pictures, the left perspective and the right perspective, these 2 will overlap and create an illusion of 3D. There is a rule we have to follow in creating a 3D image, the layer that moves the least is closest to the viewer, so therefore, the distance of a layer between left and right can be ordered as followed from smallest to largest distance: Hand/Axe < Body < Background Here I have created 2 images, one left, and one right. Warning: Spoilers inside! I moved the background 20px left, the body 10px left, and the hand/axe 3px left. Warning: Spoilers inside! I moved the background 20px right, the body 10px right, and the hand/axe 3px right. Part 3 - Creating a 3D MPO file Open your downloaded MPO 3D Creator. Go to File>Open Left/Right Images... Select the 2 files you have recently prepared and you should get the following: Warning: Spoilers inside! Press File>Save MPO File | Check the radio button at the bottom "For Nintendo 3DS" Replace your HNI_xxxx.MPO and you are done. Go view your work in 3DS Camera app. Sample Files Here's the sample files I prepared before hand, the finished product: https://www.mediafire.com/?eo79rt000f189ii HAVE FUN IN 3D!
