I hear you. There’s more than one way to convert a 3D model to pixel art. This is how I did it, but it might not be the most efficient. For those who want a simpler approach, I’ve included some awesome tools at the end that do a fantastic job with less control over the final quality.
Here’s the process I used:
-
I started by creating the 3D asset pack itself. To make coloring easier later, I used vertex colors to differentiate the object’s faces.
-
With the models done, I used a fixed lighting and camera setup to render the objects at a desired resolution. Here’s a tip: ensure all your objects are modeled to scale with each other. Render the largest object first at your chosen resolution, then use the same resolution for the smallest prop to see if the pixel density works for your game. For mine, I went with a slightly higher resolutiion for a balance between a pixelated look and avoiding excessive blockiness.
-
Once rendered, I imported the images into my preferred pixel art tool (Aseprite in this case). Here, I made any necessary adjustments, added colors, or limited the color palette to fit the desired style.
While my method works, there are some fantastic tools that can streamline this process:
- PixelOver: This free tool (https://deakcor.itch.io/pixelover) lets you convert images, gifs, and even 3D models into pixel art. Plus, it offers real-time animation capabilities!
- SLyk Image2Pixel: Skip the expensive pixel art tools, here’s a free option, SLyk Image to Pixel (https://captain4lk.itch.io/slk-img2pixel) does a way better job of converting images to pixel art.
