@dast So sad to see you go Daniel, but I can totally understand. I made a bunch of my plugins free (or cheap as chips) for very similar reasons.
Back when R20 was released and the changes imposed on developers with the new SDK, it made being a C++ developer much harder. Then with R21 every developer was forced to develop their own licensing system from scratch. And since then it has only gotten more complicated having to manage and update the plugins for every new release, then paying for a subscription and finally the last kick was Catalina requiring its own special notarization pipeline.
With all of these issues combined I foresee that we will eventually loose all the small/hobby C++ developers. It is simply too difficult to build, maintain and provide support for. And for any new developer coming on board, it is so much more complicated and harder to even get started now than it was 10 years ago. I don't think people truly realize how hard it is to make these plugins and how much time it takes for developers to learn how to do it and then use those skills to create something. And after all that effort MAXON changes the system making your efforts obsolete as well as your knowledge, since the sdk changed and you can no longer do things the same way forcing you to throw away years of work.
So for anyone reading this... please buy Daniels plugins. He spent a tonne of his time building these for you all.
Best of luck Daniel. I hope to keep seeing you around here showing off some of your new renders.
