[current employee of Autodesk] Minor contributions to existing OSS are generally encouraged day-to-day by employees.

There are also more strategic open source initiatives such as the USD stuff covered here.

Many of us, especially in the research division, would love to put more code out there. (For example some tools that we use internally) The good news on this front is that there is now a sanctioned process for this to happen, and the attitude seems much warmer than when I joined a decade ago.

I’m personally involved in trying to open source some of my own work in the robotics domain, and have been pleasantly surprised with the response.
