Hope to hear more about this unannounced product soon.

Are you allowed to say when you started working on this project ?

And when the project started (if not the same as previous question) ?

:-)

I'd love to read that performance post-mortem :)

I hope you'll find some time to write it!

Hey Torgo. Congrats on the new project. As sad as I was to see Aces canned and FS11 lost, I do know how you feel having a fresh slate to work with, and as you say the ability to run wild trying new things. :)

I too am looking forward to the performance postmortem. I've learned a ton from your blog posts.

Anyway, I'd like to ask one more arcane FSX sdk question if you don't mind? It's another of those things that probably only you know the answer to, hehe. You mentioned in an older post that the model compiler does some automatic welding of vertices in an object within a certain threshold, about 4mm I think? I was wondering if there's a hidden way to keep it from doing that? I have a situation where I have several layers of nearly coplanar polys in a single object that absolutely need to be within 4mm of each other and I can't allow the compiler to weld them. Letting it do so seems to freak some videocards out, having 10 polys sharing 4 vertices hehe.

Breaking them into separate objects is one way around it I guess but I'd like to avoid more draw calls. Would making the object a skinned mesh also work for keeping them from being welded by the compiler, because it would have to maintain them separately to keep their weight values intact? I've tried it but it's hard to know if it succeeded or not, thought you might know how the compiler deals with stuff like that. If I'm way off target there, please let me know.

Anyway, sorry for the long winded question. I would ask it in one of the developer forums but it would be pointless I think. I doubt anyone would know the answer except the person that wrote this stuff. :)

Cheers mate, and best of luck on the new gig!
