me too! ive been wanting to make one like this. im taking 3d art right now at school, i think you just export it as a lower quality? im gonna try it sometime when im not swamped with school work
Hello! The 3D assets are just standard, low-poly models made in Blender.
To get that low-res look ingame, just use unfiltered, pixelated images as textures and a low render scale.
The distortion effect can be replicated with custom shaders (I think there are some PSX shaders available for free for the most common engines).
Good luck!
