The indie game Legend of Grimrock
has its dungeon editor in public beta for those with the steam version of the game. Along with this, the developers have posted basic guides on how to use the tools.
The problem is that Grimrock uses a custom model file format, .model , and they themselves can't release custom exporters (even for Modo which they used, because they have a full pipeline that converted everything, not an individual exporter)
The specifications for the .model format can be found here
My question: How much work is it to make an exporter? I highly doubt I could do so myself (I only know very very basic python). I expect 3ds max / Maya users will get an exporter fairly soon, but Modo users like myself might be left out a little longer. So, can anyone shed any light on the process required for a custom exporter - ie would it be reasonable to ask for someone to have a go at it, or is it a complicated task? Is there any recommended reading on the subject, or any other general comments?
