Rombo Tools is deeply integrated into the Cycles rendering kernel. To achieve native C++ performance and GPU acceleration (CUDA/OptiX) without the limitations of standard addons, we provide a full custom build of Blender Cycles, RT-Cycles ! It is the official Cycles release engineered with our shading tools on top and compiled directly into the core for uncomparable speed and consistency (vs node-based addons).
Seamless Integration
Because this is built on the official Blender codebase, it respects your existing environment completely:
- ✓ Reads your existing User Preferences.
- ✓ Loads all your currently installed Addons.
- ✓ Opens your existing .blend files perfectly.
- ✓ GPU Kernels are pre-compiled (no wait time).
How to Install
The installation process is "Portable," meaning you do not need to run an installer wizard or have admin privileges. You can keep multiple versions of Blender side-by-side without conflict.
Download
Download the blender-windows-x64-rombotools.zip.
Unpack
Extract the ZIP file anywhere on your hard disk.
Run
Double-click blender.exe inside the folder. That's it!
You will find the new nodes in the Shader Editor under Add → RomboTools menu.
The Architecture: Why C++ Matters
Most "procedural addons" on the market are just collections of standard Blender nodes wrapped in a group. Rombo Tools is different. We extended the render engine itself.
- Interpreter Overhead: Cycles must parse and execute individual nodes for every single pixel.
- Memory Bloat: Massive node graphs increase kernel memory usage and compilation time.
- Fragile: "Spaghetti" graphs are hard to debug and easy to break.
- Zero Overhead: Algorithms run as optimized machine code (PTX/CUDA) directly on the GPU.
- Atomic Nodes: Replaces hundreds of nodes with a single, highly-optimized instruction.
- Stability: Rigorously unit-tested math kernels ensure consistent results without artifacts.

Common Questions
Will this overwrite my official Blender?
No. Since it is a portable zip, it lives in its own folder. Your standard Blender installation remains untouched.
Do I need to reinstall my addons?
No. Blender stores user preferences and addons in a global folder and our build reads from this same folder (as any other build), so all your existing tools will load automatically.
What happens when Blender X comes out?
We closely track the Blender release cycle. When a new release is out, we will have already re-compiled our core against it because we do test and work on beta Blender builds.
