Moore Chair

I found a really nice chair in UPenn's Moore Engineering Building and decided to try modeling it for class.

Tech stack

Maya, Substance Painter

For my 3D Modeling class our first assignment was to try and model a regular object from your daily life. I was looking for ideas, walking around the Engineering Quad when I entered Moore and saw this chair. I proceeded to take pictures from all angles for reference later.

Overview of the reference images I took

Reference images. I hope no one saw me flipping chairs for 10 minutes straight.

This was my first time using Autodesk Maya so I wanted to start with something relatively simple. I began by blocking out general shapes before going in and beveling and extruding out the details. To get the slight “arching” of the upper half seat, I enabled soft selection and gently pulled one of the central vertices back.

Substance Painter

After assigning geometry different materials and (somewhat) figuring out UVs, I exported the chair as a FBX and imported it into Painter.

Most of the materials came with Painter by default. I simply searched for leather and metallic materials and adjusted some of the colors and roughness maps (I mostly increased roughness; the Moore chairs were in rough shape).

I added small white cracks on the seat’s surface by adding a mask layer and painting with a negative height map.

Rendering

I used Arnold to render. Unfortunately, Arnold GPU rendering requires a NVIDIA GPU and I have AMD. Also, I decided to try rendering on my laptop instead of a proper workstation. This was a mistake.

It took me 15 hours to render 240 frames. Each frame took ~2.5 minutes. So I’m never trying that again. But at least the end result looks nice!
