Well, I was surprised today to open Steam and see 'instal Modo Indie'. I had Modo Steam, they haven't been upgrading/bugfixing it. So maybe they are just going with Modo Indie now? Anyway, it's an 801 SP4 package of some sort. More stuff than SE had (animation, rendering). So I dl'ed this script and tried it but nothing…
No, sorry. No scripts or Python API/C++ SDK plugins allowed for ModoSE. However, I'm talking to them about potentially having it added once it's in a good enough state. I'll probably have to port it to C++ for that, though.
