Tsar Hoikas has gotten the Max plugin building in max 2011. It doesn't quite run right yet, but it's mostly working. We'll keep all of you max-using Writers updated on the situation, and you'll be the first ones to know when we've got something ready to test.
I'd also like to make a shout out to anyone with any older versions of Max between 8 and 2010. We need people who legally have access to the SDK to compile the plugin for those older versions of the software. You'll need sufficient computer skills to click the right buttons and type a few commands, but we can walk you through the process. This isn't an immediate need, since we're stilll working out some of the bugs on more modern max versions.
