The short-term plan (next 4-5 years) is to keep using it. This plan is regardless if XSI is still developed or not. The reasons are:
- As a small studio, we don't spend money on updates or subscriptions unless there're some important features that have strong impact on our production.
- Since Autodesk starts releasing XSI every year, we rarely found such important features to us.
The result was renewing licences every 2 years in best scenarios.
For the long-term it is not decided yet. The next candidate from Autodesk was Maya. Its workflow is closer to XSI than Max. However noticing Autodesk development strategy in Max and Maya after stopping XSI, it is confusing XSI studios where to go, and in some cases it is pushing them away to Houdini.
As an XSI user/studio who heavily depends on ICE and planning to switch to the closest Autodesk product (e.g. Maya), I expect to see Autodesk's roadmap for Maya covering procedural content creation to keep XSI users and attract more users/studios to them who are adapting procedural creation.
However, instead of spending the effort implementing this system in Maya, for some strange reason they decided to start this project in MAX with MCG
So Houdini is becoming more attractive for us since we believe the future is with procedural content creation and Autodesk decided to stop their best DCC on that front and start again from scratch in the wrong DCC.
