Ryven plugin for Blender

This repo consists of a tiny file for loading Ryven as a plugin in Blender, as well as nodes packages. Notice that there are no nodes at all available yet, because I don't know the Blender Python API well. If you do, please consider contributing.

While Blender itself already has an impressive built-in nodes-based material editor, the simplicity of Ryven together with the extensive Blender Python API might enable much more rapid development of new nodes.

setup

Step 1: Find the path to your Blender's Python executable

something like

C:\Program Files\Blender Foundation\Blender 2.93\2.93\python\bin\python

I will refer to the Blender Python path as <BPP> from now on.

Step 2: Install Ryven and bqt

Run a terminal with admin/root privileges and execute

"<BPP>" -m pip install ryven
"<BPP>" -m pip install bqt

Installing packages into Blender's Python can be quite fiddly sometimes.

Step 3: Add the plugin

Clone this repository into the addons dir of your Blender installation

cd <Blender-Path>/<ver>/scripts/addons/
git clone https://github.com/leon-thomm/ryven-blender

Step 4: Load the plugin

Open Blender as administrator (to grant ryven read access to its installation directory in Blender's Python). Under Edit => Preferences => Add-ons you should now find Open Ryven Editor. If not, click install and select the ryven-blender/__init__.py file.

By pressing F3 in Blender you should now find Open Ryven Editor as command which simply shows the editor window, closing the Ryven editor window doesn't kill its content.

adding nodes

To add nodes, see blender_nodes/nodes.py and blender_nodes/basic.py for some examples.
