WZ, what kind of input do you need?
Will the program generate havok data based on a mesh that's loaded into it?
Here's some random thoughts on this:
- Add options for material settings (similar to those found in the Nifprops section in the 3DS max plugin)
- The program would have to probably count and calculate vertex or poly coordinates in order to genrate data accurately.
- Then based off of those calculations, the program could auto generate a simplified havok model and let you choose options for materials.
Some questions:
- Isn't the Niftools project open source? wouldn't it perhaps be easier to add the havok options to the existing NifSkope program? or even the exporter?
- I thought Havok was legally protected. Hence the reason Bethsoft never rekeased an official exporter.
Either way...great job and good luck on your project. I'll keep a close eye on this one
