Fake Bumping

Lighting and cubemaps are a big part of the bumping process in halo, they won't work with these bumps properly and will at worst cause visual anomalies, and at the least won't look right.

Also, just a note about normals... the R and G channels don't always act the same between programs. There isn't really a uniform way to do it really... different programs use the information differently and so depending on what you're going into you might have to invert certain channels. For example, Maya and UT3 use the green channel opposite of each other, so for one you'll leave it fine and have to invert it for another.

In halo CE you cant have bump maps on dynamic objects. Only on the BSP model. And even so, halo CE uses the oldest form of normal maps so there isn't really any depth added with a normal map.

Anton and I used this same process a couple of months of back to give BiMyrrha's rock texture more depth.

It is pretty cool. You are just amplifying the black and white, but it is a nice effect nonetheless.

The blue channel of a bump map is just in and out data, which is the same as a normal bump map, so you should be able to either use it directly, or tweak it a bit for it before using it.

Wasn't sure about the bump on dynamics though... silly HCE

I'm slowly making the change to unreal engine.(60%)
*high five*

You just destroyed the integrity of the normal map...>_<.

Also I agree with rentafence, I'm not a fan of these fake bumps, it makes them look dirter than normal and I can tell you, chief is not a dirty guy.

So from Halo 2 to Halo 3, Masterchief hasn't gotten one spec of dirt on his armor? He must be using OxiClean.

Theres a big difference between dirt and scratches/dents.

He doesnt have dirt on his H3 armor, he does have new scratches/dents though.

Well Bungie used different bitmaps for campaign and multiplayer. Multiplayer had cleaner spartans, campaign had some dents and scratches.

The lower calf and boot areas look like dirt to me, as so do other spots on the armor.
