Foundry were kind enough to run a webinar with me talking about An Artist's Guide to Blinkscript and have a Q&A about Blinkscript in general.
You can check it out here: https://app.livestorm.co/foundry/foundry-skill-up-an-artists-guide-to-blinkscript
Feel free to get in contact if you have any further questions, or just fancy chatting about nodes.
