Hello, It’s been a while since I shared any project here on BA!
These past few days I’ve gotten inspired to do some hard surface modeling, so I made the “Upgraded Robot” from the game Mother 3.
The model has a very basic rig since I only needed to pose it for the render. The legs have IK bones but everything else uses a simple FK rig.
I used the principled BSDF shader everywhere but the materials are very much not realistic. I found the new principled BSDF in 4.0 to be much easier to control and it allows for a lot more experimentation than the older version!
The light beam for the eye is a cone mesh with an emission shader and a bunch of nodes to get the shape right:
The grey metal parts use a matcap texture mixed into the color for a stylized metal effect. The metallic value is actually set to zero.
Matcap texture by itself / Final material with shading:
The glass material took a lot of tweaking until I got something I was happy with. It is a glossy surface that uses fresnel as a factor for the alpha transparency. To get the blue tint I added volume absorption and volume emission together.
For the lighting I just did a simple setup with a fill light at the front, a rim light at the back, and a separate rim light only for the glass. I used light linking to mask the rim lights to the correct objects only.
And finally, for reference, here’s what the original sprite from the game looks like:
Thanks for checking it out!
