Interactive archviz with Blueprints

Unreal Engine 4/5 Blueprints for Architecture & Virtual Scenarios is an online course that teaches Blueprints, Unreal Engine's visual scripting system, to turn architectural visualizations into interactive experiences. You connect nodes instead of writing C++ and build doors, lights, material swaps, menus and camera modes step by step.

1. 1 · Learn the language

   The editor, variables, arrays, flow control, functions and Blueprint communication: the base every interaction uses.

2. 2 · Build real systems

   Timelines, vectors, materials and UI widgets become doors, light dimmers, a time-of-day control and an elevator.

3. 3 · Ship an interactive project

   Put it all together in a complete archviz walkthrough with menus, level streaming, a minimap, camera modes and save/load.

02 · Audience

Who it is for

Built for people who make spaces look real — and now want people to walk through them.

• Architects and archviz artists

  You already render in Unreal Engine. Now let clients walk through, open doors and switch finishes in real time.

• Real-time 3D artists

  Product visualization, configurators, virtual production, training and digital twins: the same Blueprints drive them all.

• Students and beginner developers

  No programming background needed. We start from the editor and build up, node by node.

• Studios and freelancers

  Add interactive tours, configurators and menus to your services — and charge for them.

Daniel Falci

Unreal Engine Technical Artist & Tech Lead · Belo Horizonte, Brazil

Daniel Falci is an Unreal Engine technical artist and tech lead with more than 15 years in interactive technology, building real-time architectural experiences since the early days of Unreal Engine 4.

He co-founded UE4Arch, a studio specialized in interactive virtual scenarios, where he owned the Blueprints, UI and systems layer together with project management and pipelines. UE4Arch delivered projects for Amazon, Autodesk and Epic Games, served more than 5,000 customers worldwide and received two Epic Games grants (MegaGrant 2021 and Unreal Dev Grant 2016). Its “Loft” project was one of the first interactive real-time archviz scenes and passed 1.5 million views on YouTube.

Today he works as one of the tech leads at ResVR, a Canadian company whose cloud platform replaces static plans with interactive 3D showhomes: homebuyers across North America explore floor plans, finishes and upgrades in real time, and builders report around 28% more upgrade revenue.

This course collects the Blueprint techniques he uses in practice — from the first node to a complete interactive project.
