Yes. It doesn't come with 3.5.8 but I found it and put it in max's plugin folder. crytools installer said everything was ok. It added itself to max's interface. I exported the materials with it. I don't know what to do.
they don't provide the cryexporter for 3ds max 2015 with the free SDK anymore because it wasn't ready at that time According to Cry-Adam you also need at least CryEngine vers. 3.6.x for the files exported with 3ds max 2015 to work
Unfortunately an 'export failed' error is not really very helpful or informative, as is typical of Cryengine documentation. Maybe you could acquire a different version of the resource compiler (rc.exe) and try that, or see if you can get it working with a Max 2014 demo first and the RC and plugin that come with the free…
I am having the exact problem for the last 4 days. Using 3.6.6 . Have no idea why. Here is what I got with mine ( 3ds max 2013) Working fine until Monday.
