Hey there! Let’s cut straight to what you need: no-code 3D game engines since you can’t use Unreal, and Unity’s coding requirement makes it a non-starter for you. I totally get why generic recommendation lists that throw Unity in there feel frustrating—they often skip over the "no-code" context that matters most to you. Here are my top curated picks:

1. Godot (Visual Scripting First) #

Don’t write off Godot just yet—its built-in visual scripting system is a game-changer for no-code development. You’ll use a node-based graph to connect logic blocks, handle signals, and build entire 3D games without touching a single line of code. It’s lightweight, open-source, and has robust 3D tools for level design, animation, and physics. Unlike Unity, coding is 100% optional here.

2. GameMaker Studio 2 (Drag-and-Drop 3D) #

GameMaker is famous for its intuitive drag-and-drop (DnD) system, and while it’s often linked to 2D, its latest versions have solid 3D support. You can create movement, collisions, AI, and game rules by dragging pre-built action blocks into your project. It supports cross-platform exports, so you can share your game on PC, consoles, or mobile without writing code.

3. Construct 3 (3D Beta, Browser-Based No-Code) #

Construct 3 has long been a go-to for no-code 2D games, but its 3D beta is now mature enough for most projects. It uses a visual event sheet system—you point-and-click to define logic like "when player collides with enemy, decrease health." No downloads required (it runs in your browser), and importing 3D assets is straightforward.

4. Defold (Open-Source Visual Scripting) #

Defold is a free, open-source engine with a dedicated visual scripting tool that lets you build 3D game logic via node connections. It’s designed for simplicity, making it great for smaller to mid-sized projects. Plus, it offers cross-platform support for PC, mobile, and even web games—all without coding.

5. Stride (Formerly Xenko) #

Stride is an open-source engine with a deeply integrated visual scripting system. You can design 3D levels, set up character animations, and program game behavior entirely through a node-based interface. It supports multiple rendering pipelines, so you can customize your game’s look without writing a single line of code.

Quick Note on Unity’s "No-Code" Reputation #

You’re right to be confused—Unity does have a Visual Scripting package (formerly Bolt) that allows no-code development, but it’s not as intuitive or fully featured as the dedicated engines above. Most recommendations for Unity focus on its coding workflows because that’s where its biggest strengths lie, which is why it’s a poor fit for someone who wants to avoid coding entirely.

Hope these options give you a clear path forward for your 3D game project. Feel free to ask if you want deeper details on any of these engines!
