Re: Spyro Nostalgia

Wow this is really awesome. Good job on finding out the level geometry btw.

If you need any help on this I'll be more than glad to give it a shot. I probably can't help you that much in modeling seeing I only have brief experience in that department, but I could help you out with other aspects associated, (programming, story-line, etc).

Good luck.

Re: Spyro Nostalgia

Thanks smile

The really cool part is that since the textures are available and what with the geometry being as low-poly as it is, it shouldn't be too hard to add things to them or extend them while still making them look authentic.
It would be quite something to pull that off.

Re: Spyro Nostalgia

This is too good to exist. But why are you placing gems at the mountains, where the player doesn't have any access? ._. Or are they generated randomly?


Never ask what I'd do for a klondike bar. No one wants to go down that road.

Re: Spyro Nostalgia

It says under the first screenshot that they are randomly placed.

This is awesome; great work. smile If you ever have this completed to your satisfaction, I'm sure we'd all like to try it out.

That document you found might be interesting as well, if you wanted to share that.

`Vram` is the first sub-subfile of a `level` (marked `Vram zone` above)

`Model` is a beginning of second sub-subfile,
 Size = `j1` (just before first `sky`, see `Second sub-subfile`)
