Supermodel Forum

When working with flat polys I used mainly the first running demo of Harley and some particular case of the first car demo in Le Mans 24. The latter It's not perfect, see below:

(left: Model 3, right: Supermodel)

look to the rear spoiler, on the original hw the highlight suddenly disappears at some angles instead of fading out like in my solution. Also the front one is darker on original hw and while being flat is marked as smooth poly so inherits the same parameters as the rest of the car.

Harley's surrounding buildings:


Please note that on original hw the flat poly highlight is brighter if the poly is parallel to the camera plane (i.e. it's face normal perpendicular to it) and fades out a little when changing angle. I tried to emulate that effect with the help of the Blinn-Phong solution. Check Abe's Harley direct capture as reference.

Updated Patch for r675:

- Further improved specular coefficients for more arcade-like accuracy.
- Experimental 256-level posterization applied to specular shading. It's subtle in many games, but it's really evident in Harley as seen in Abe's video; it doesn't seem like a compression codec artifact.

Ian, have you tried the new patch? What do you think? The differences are more marked in LeMans 24, Scud and Daytona 2.

Specular on flat polygons is still wrong, but I'm working on that.

I haven't tried it yet Harry. I haven't done much work on specular really, apart from my very early attempts, so I don't really have any good test cases
it's on the to do list though

Harry, Ian.

Reflection of the previous post is weak (Fighting Vipers Grace character victory pose)
I wonder if it has been fixed in the new patch.

And the reflection comparison is a more obvious save file.

Yoyo,
can you post some comparison screenshots? Thanks

r674 and r677 reflection comparison
Compared with the r674 version, it makes a big difference.

What does the original hardware look like?

As Ian said a high quality arcade screenshots could be useful but it seems there's none around.

That said I'd bet the correct one appears to be r677, not only because visually seems more appropriate for a skin "reflection" (it's not made of steel ), but most importantly because from r675 Supermodel sends polygon header properties to shaders (almost) the right way due to some changes in polygon caching.

For example: in LeMans 24, compared with arcade direct video-captures, cars reflection are now much more correct.

Hello

I found an image of Fighting Vipers 2 from a scanned image of a magazine

Because stage and lighting are not the same, it will not be a perfect comparison
But the new revision seems to be similar
