Perfecting the Sketchup modeling workflow, discovering a new iconic building from F.L. Wright, eventually visiting the Jacobs House 3D model with Unreal Engine. Overall a simple project on paper, with a few technical and architectural lessons along the way to get to the end goal of realistic animation renders.

All the 3D base files associated with the Jacobs House model are available here in CG Trader. The native format is Sketchup 2022 with components and layers well organized, modeled in real world scale with pretty close accuracy.

The impulse of the Jacobs House project

Recently going through a ‘Greatest buildings of the 20th Century’ book, I saw a bunch of projects from a certain Frank Lloyd Wright, big surprise. In the middle, this small house from his, the Jacobs House, caught my attention.

I’d always heard abouth his famous prairie style house, and this one had something special about it, a sense pf both simplicity and a completeness. I learned later that the Jacobs House, builti in 1936, was considered the first of his Usonian Houses, a blueprint of success for dozens of future projects.

Forget the Falling Water, the Guggenheim (for now), I’m diving into the Jacobs House. I knew it once I saw it, I am going to build in from scratch on my screen. As I would built the house brick by brick on my plot of land, if only I had one that big.

This would also be my opportunity to visit, in my own way.

Getting started with the Jacobs house

A a starting point, I only could find a few 2D floor plans and section that I retraced on Autocad and scaled right. Plus a ton of photo reference of the house, interior and exterior shots, glaning all the details to try to eyeball it the best I could after. Detailed process in the step-by-step later on.

Final results

Final animation tour edited with a little bit of music to get an all around feel for the Jacobs House in a 3D Unreal Engine set up. Trying to get a little bit more realistic in the renders while still playing with the camera moves of this virtual home :

Making of the Jacobs House 3D model: step by step

Getting back on my now usual M.O., trying to get faster as well on each step, you how we do :

1. Setting the objective
2. Making a reference image library with Pureref
3. Drawing the 2D base in Autocad
4. Sketchup file set up: units, base image, scale
5. Modeling using components and layers, efficient scenes
6. Choosing the textures (Megascans Library from Quixel Bridge)
7. Final touches in Sketchup : materials and UV mapping
8. Export Sketchup file into Datasmith
9. Importing Datasmith into Unreal Engine 5.1 project
10. Material assignment and Foliage building in Unreal Engine
11. Fbx import for the house furniture
12. Cameras and renders from Unreal Engine, screenshots
13. Stepping back and improving the scenes little by little, just by looking at them
14. Choosing the final shots and rendering level sequences with movie render queue
15. Da Vinci Resolve to transform png sequences into video file
16. End result : HD video renders of the main parts of the Jacobs House

Conclusion

In terms of scale, this wasn’t the scariest Wright building to model, but still a very interesting one to dive into. The Skecthup workflow is now pretty dead on, and the bridge between Sketchup and Unreal via Datasmith is beginning to take form.

A lot of back and forth between Skecthup and Unreal on this project will hopefully take less time on the next one. This Skecthup-Unreal connexion and the specificities of Datasmith exporting will need a special article.

Roughly 35 hours of work between the first (virtual) brick and the video render, gives a good enough idea of how long it takes to get from a simple 2D base to a pretty realistic and lived-in 3D environment.

I’ll come back to Wright later, but for now, onto the next one,
