229: Campfire Series - 'The CGarchitect Story', with Jeff Mottle
A conversation with Jeff Mottle about building CGarchitect from a side project into a 21‑year global hub, its sale to Chaos Group, his NVIDIA tenure, and the impact of AI on architectural visualization.
In this special Campfire Series episode, Jeff Mottle joins the podcast to tell us the full story of CGarchitect — from a side project launched in 2001 to a 21-year platform, a sale to Chaos Group, and everything in between: the 3D Awards, CGschool, the evolution of archviz from expert-only technical gatekeeping to storytelling, and what COVID revealed when it stripped away all the travel and in-person events that had been keeping him going. We also get into his four years at NVIDIA, the AI wave he'd been predicting for nearly a decade before it hit, and why the AEC industry's instinct to wait for a clear winner may be the costliest mistake it makes.
This episode is especially relevant for visualization professionals, design technologists, and firm leaders watching AI reshape the tools they've built careers around. Jeff makes a direct case that the democratization of archviz didn't start with AI — the last 5% just got sped up — and he's specific about why billing by the hour is the industry's biggest liability going forward and what a shift to outcome-based pricing actually looks like.

CGarchitect & CGconnect
- CGconnect (formerly CGarchitect)
- cgconnect.chaos.com
- The platform Jeff founded in 2001 as CGarchitect and ran for 21 years before Chaos Group acquired it in 2022. It has since been rebranded as CGconnect. Still the central hub for the architectural visualization community globally.
- Chaos Acquires CGarchitect
- Announcement
- The announcement when the sale Jeff describes in this episode was made public.
People From the Story
- Joseph Kosinski
- Wikipedia
- Film director (Top Gun: Maverick, Oblivion, Tron: Legacy) who trained as an architect at Columbia University and got his start in CGI commercials and archviz. Jeff describes him as a pioneer of cinematic, cut-driven real estate films and was one of the first to treat an architectural animation like a short film rather than a continuous camera path.
- Henrik Wann Jensen
- UCSD Faculty Page
- Computer graphics researcher known for developing photon mapping, a global illumination algorithm that helped make photoreal rendering practical. Jeff mentions interviewing Jensen in CGarchitect's early days as one of the pioneers whose work shaped the tools the archviz community was built around.
Tools of the Era
- Autodesk 3ds Max
- autodesk.com/products/3ds-max
- The 3D modeling and rendering tool at the center of professional archviz for decades. Jeff's first encounter was 3D Studio DOS, the DOS-era precursor, when his boss dropped it on his desk with no instructions.
- Lumion
- lumion.com
- One of the real-time rendering tools Jeff points to as an early inflection point in archviz democratization making visualization accessible to architects who hadn't trained as visualization specialists.
- The Gnomon Workshop
- thegnomonworkshop.com
- Professional online training for 3D artists that Jeff mentions as the analog he was most aware of when building CGschool. Sets the standard for what serious CG training could look like.
- NVIDIA
- nvidia.com
- Where Jeff worked for four years after selling CGarchitect, managing developer relations for the AECO ecosystem and bridging NVIDIA GPU and AI technology to AEC software.
Archviz Studios Mentioned
- Neoscape
- neoscape.com
- Boston-based archviz and creative agency founded in 1995. Jeff partnered with Neoscape's Lon Grohs on CGschool training events, and eventually hired Grohs at NVIDIA to manage rendering partnerships; a full-circle moment he describes in this episode.
- Transparent House
- transparenthouse.com
- San Francisco-based architectural visualization studio. Jeff mentions they hosted CGschool training sessions at their SF location alongside the Boston events with Neoscape.

About Jeff Mottle:
Jeff Mottle is a recognized leader in the architectural visualization industry with nearly three decades of experience spanning production, business, and technology. In 2001, he founded CGarchitect, which grew over 21 years into the leading global community and media platform for architectural visualization professionals before its acquisition by Chaos Group. He went on to spend four years at NVIDIA as Industry Partnership Manager for AECO, leading developer relations across the AECO ecosystem and working with the leading ISVs to advance their platforms through NVIDIA accelerated computing, AI, and Omniverse.
Across his career, Jeff has worked as a production visualization artist, technical director, business development lead, and CEO, and has been a published author and frequent contributor to industry publications. Now retired from full-time industry roles, he remains available for select consulting and advisory engagements where his experience across the visualization, AECO, and developer-relations landscape can add value.
