The Blender Terrain video set isn’t necessarily ‘exclusive’ to D3/Q4 per say, it’s just ‘a method of production’, so it certainly can be used for QW… I know I’ll be doing terrain that way from now on as I hate ‘game boobs’ (heightmap based terrains).
Regarding the ‘free’ student edition of Maya. There isn’t one. There is an ‘educational’ version of Maya which is basically the full app available on a limited licence basis to full time students at greatly reduced costs (about £200 or so instead of close to £1000).
What you’re thinking of though is MayaPLE, that is free but it has limited functionality from the point of view of exporting models; it’s pretty much the same as gmax in that it needs a ‘gamepack’ - the ability to export to a suitable format has to be added to PLE.
Question for Wils (if you’re allowed to answer this one):
If you’re making the terrain in Maya is is safe to assuming that means you’ve got direct support *.ma (maya’s native file) format?
Are *.ASE and *.LWO files still going to useable for terrain models?
