So i am getting into texturing, to see if i'm any good at it, and am starting out with modding existing textures, to get the hang of things. So i was looking through some shaders and i sough some that i think would look better with a bump so i was wandering how i am to make that?. Just hoping to hear back soon and my final thought is can i do thins for free? like without photoshop

Bump mapping tutorial. I think it's the one I used...

A Bump map is not made by texturing.

It is where you model an EXTREMELEY detailed model, usually a sub-division model that consists of hundreds of thousands of polies, and it simulates a light reflecting off the model, and captures all the angles and how light would reflect off the model at every angle, and the program would render a texture.

You can't "make" a bump, officially.
There are fake bumps makers, such as CrazyBump or nVidia DDS mapper you could use, but results aren't the greatest.

So based off what I've just read your saying game makers make high poly models for all there bump maps.....NO!

I think you got normal maps and bump maps confused.

When I see people make normal maps they usually make it off high poly models.

But bump maps aka old and crappy height maps,I've always seen someone make the texture, never a high poly method to make a simple grey scale image.

Correct.... my bad xD

I'm so used the them being the same, 3ds calls normals bumps.. So does Halo 3 "zbumps"

This works, doesnt seem like bungie's.

Bungie's honestly look hand made, they just make them in photoshop, Dark is deeper, Light is more shallow, so keep that in mind and just make a texture, and use the different shades where appropriate, or perhaps go over your original textures while doing this.

It's that simple? Is that a fake bump? And thanks

No there's no such think as a fake bump, I was thinking of normals.
There are fake normal maps, but bumps maps are bump maps.

Then why have i heard of fake bumping before if it doesn't exist? Lol

People being dumb and mistaking Normal mapping for bumping.

Halo CE doesn't support normal mapping on moving objects.
So they take the normal map and do some edits onto the diffuse texture to make it look like there is a normal map for an enhanced look, but it doesn't really make the model normalized.

This is called fake bumping, but has NOTHING to do with bump maps, but Normal Maps.

Lol okay thanks for clearing it up and thanks for the tutorial, but i think i'm doing something wrong. I make my new bump and apply it and it still looks flat, no change in the reflections at all, i'm sure "shrugs" i'll figure it out at some point

There should be no change in reflections. Do exactly what the tutorial says, forget what I said at first, that is NORMAL mapping, your focusing on BUMP mapping, there easy to get confused. Reflections are HOW Normal maps are made, but your making a bump map, it should come out gray scale and only shades of gray, white through black. So if its dull your doing it right.

Okay..... In order for a bumpmap to ACT like a bumpmap, the properties of the BITMAP must be changed. Because i'm not at my true computer, I can only vaguely describe what to change.

In the bitmap of your bumpmap, there are many checkboxes, they are grouped. There is a checkbox in one of the groups that says disable height map compression, and above that group of checkboxes, there is a comboBox that tells the bitmap how to interact within Halo's engine, Just switch it to "Height map", and below the checkboxes, there is a form labeled "Bump height(or something like this)", set it to something, but don't go over 1.0

Once you've done this, just recompile your bumpmap's .bitmap :)

@IHalo-A bump map will change how the reflections react ingame, in other words, it will not show any of the reflection map where the bumpmap tells it it is supposed to be lower, dents, indentations, ect, so thats what i meant by my statement.

@orangejuice- Thank you i will try that and get back to you, shouldn't take to long.

Oh! and make sure the bumpmap has 32-bit color, "disable height map compression" is optional.

if you take off somethings bump map and look at it ingame it will look flat. The reflections will be completely flat and not bend over it like it has indentations, put it back on. and it does. So that's where i was getting the idea that bumpmaps affect reflections. So if i was wrong then try what i just said and tell me what i'm seeing please lol

Lol that's somewhat what i was saying. It creates the illusion of "depth" and the game will work with that and the reflections and speculer to make it look as 3-D as possible in halo's engine. But if you had the bump on and it still had a seemingly flat reflection glossed over the top and it didn't fallow the contour that the bump had laid out it would look quite off to the person playing, i think.

EDIT:And if by "over complicate things" you think i can't understand the technical terms and explanations please go for it and i'll do my best to comprehend the facts set out by the experienced texturer

@Ihalo

Bump maps, aka heightmaps, get turned into the blue/purple-y tangent space Normals map. They're basically the same thing because they can reproduce the same effects when done right. Zbumps are tangent space normals NOT made from high-poly models, but from zbrush, a program that can be used to "brush" in bumps and normals.

Bungie used zbrush most likely to create their zbump normals and modeled high poly models to create their other normals.

@ IHalo


It's cool bro.


The thing is there a few types they are:height maps {Halo 1},bumps maps,normal maps {halo 2 & UP} and {parallax mapping} and a newer form called {displacment mapping} "not to be confused with parallax mapping"

The things people are listing above all are one of these forms of bump mapping there no different.

Yours you asked about are height maps a really old form of bump mapping in halo ce.Though guerilla says bump map it's still a height map,as in the halo 2 guerilla it also says bumpmap in the shader though it is understood to be a normal map.

and the way I listed them above is the latter.

Think what you want ;)
