I don’t think this has any relevance at all regarding the work they are doing on c4d internally. This is a deal with Adobe, which pays for development of a feature. Which MAXON would use to hire, or use a developer internally, who is an expert at integrating C4D into other applications (that would be their only job). This has absolutely no impact at all on the development plans of C4D itself.
And the remaining funds from the deal can then be used to hire more developers and staff at MAXON to work on C4D itself. Its a win-win really.
C4D gets more exposure, more people get to learn C4D and use it in new workflows. More C4D jobs for in-house positions using C4D. Leading on to companies purchasing full editions.
