This past week nvukovlj announced the latest release of Realsoft3D 5.1 for IRIX on the forum:
Just wanted to let you know that Realsoft have released v5.1 of Realsoft 3D for Irix.
The package is still Beta (same as the Linux version), but basically, this doesn't mean that it is any less stable, but it does mean that it lacks behind in release schedule than the Windows version.
The benefit is that a lot of the bugs found in the Windows version are fixed by the time the Irix release comes out, and that the Irix licence can also be used for the Linux version.
The Irix and Linux versions are also considerably cheaper.
Anyway, there is an 'eval' version available for download now (not time limited, but rendering res. limited) from here:
Let me know if you encounter any problems.
Let me know if you like it as well. It would be good for Realsoft to know if anyone is interested in their keeping the Irix version going.
I'm helping out on that front (just minor aspects of the porting, so can't take credit for either the features or the bugs. ), and will keep doing that while there's interest, since I barely get to use it these days due to work commitments.
Comments and other feedback are in this forum thread. Enjoy!
