We created a Bridge plugin for Cinema 4D that can load plugins from R12 to R19 and enable them to work in R20 and R21. Where Cinema 4D R20/R21 has changed in functionality, older plugins may not work.
Please Note: The INSYDIUM Bridge is not guaranteed to work with ALL Plugins. If you find a plugin the Bridge is not compatible with, we’d like you to get in touch with the plugin developer and ask them to contact INSYDIUM direct via (c4dbridge[at]insydium.com). We can then work together to find a solution.
