Quad rendering bug

[HarryTuttle]

That's what I'm doing right now... Hope to *not* find any!

Anyway I think that will take long... *NOT*!

UPDATE:
I spoke too soon by just switching back and forth between the last two images its clear that this breaks some other poly.

In red circles = bad splits, green = good

No rush I spent quite some time trying to debug this without much success. Eliminating possibilities is an important first step

Are the quads on the car not using vertex sharing? The whole thing looks purple

In this game the cars have an invisible hull that has specular effects and dirt textures applied. I removed that and this is the result,
the difference is almost imperceptible, but it's there:

Left (default poly split rendering) = good poly, right (switched split) = bad poly

And yes, there're those type of quads even on the car, here in green shade:

OT:
thanks for r585! Now finally compiles with DEBUG set... however, when I run Supermodel like this:

Code: Select all

supermodel.exe .\roms\scud.zip -gfx-state=saves\scud.st0

It just exits immediately without writing anything to "Analysis" subdir

Have you made sure to create the Analysis subdirectory manually first?

[Bart]

Also, make sure you've made a clean build.

[HarryTuttle]

Yeah, (I forgot to specify that) I've already done both.

What does the error log say? Is there any printed output to console?
