My xfire is darklord0912

Spartan094 is gunna post here saying "LOL OVERLAY THE NORMAL MAP OVER YOUR DIFFUSE!"

The general idea of the tutorial is to multiply the blue channel of the normal map over your diffuse and adjust the levels until it appears the way you want it to be.
Where do you not understand the tutorial?

^You dont know what your saying.

nice upper people :P

Well I open the bump map provided by bungie,check the channel blue adjust the levels make it look okay,then what do I do from there?

In the tut his backround on his normal map is white but mines blue it was throwing me off :/

not sure what after that,copy the channel paste into the normal one got confused after some parts sorry :/


And ps what programs are you talking about?? Not the ones that maker normal bump maps that we cant use are you?

No no, you TAKE the blue channel of a normal map and multiply it over the diffuse. THEN you adjust the levels of it.

I can bump map,

I made a stell bulk bumpmap and grass

Fake bumping things looks horrible, it dosent add any more depth at all really, except for little shadows you can barley notice. There's other ways to do it for this engine and actually make it look better.

It helps if you provide a way to make it look better.

A fake bump mapper? Wouldn't you want a real one? Well, if you're looking for fakes, try Hong Kong.

The Black Market has tons of them! :P :P

Well, first of all, I've never done fake bumping my self before, but by just looking at the before and after pictures, I can barley see a difference really, except for sharper angles. Which imo, dosen't look good. There's a thing in Halo they use called Multipurpose maps, and Alpha maps. Correct use of these, you can "sort of" fake bump them. Alpha maps and multipurpose maps control shine. Alpha's control shine better then multi's. However, a multipurpose map does alot more then just control shine. If you read in guerrilla what it can do, and how its controlled, and with a little shader experience, you can make something pretty nice looking with one.

From guerrilla:


The alpha in the DIFFUSE map controls shine. not the multi. Don't get that mixed up.
The alpha in the diffuse can also control were 2 detail maps go. However, this doesn't work on non bsp objects. Non-bsp objects only allow one detail map.

The Self-Illumination mask can add light and things, like you would see on the pelican, or maybe the spirit dropship. You can control how the lighting acts, and what colors it goes to.

Detail maps can control shine as well, just like a diffuse map.

Alot of other stuff in Shaders is pretty self explanatory. It just takes time to learn how to use them correctly. A bit of experience and toying around doesn't hurt.

fake bump maping does make a good map look horible

What...
BSP models have actual normal maps applied to them. Its dynamic objects that do not, which is why people fake bump.

Guys Im just saying for maybe bipeds,maybe weapons,not bsp's.

oh and DEEhunter,advancebo tried it through gimp for me but he could not do it,will fake bump mapping work in gimp??

Spartan doesn't like to do things that require effort, that is why he rips.

Typical "LOL ITS JUST A GAME BRO! NOT A BIG DEAL!" excuse. Anyways, im out.

• Last time I ripped?


• Oh lol, conning people.


• "DERP DERP DERP ITS JUST PIXELS LOL!"


• "I'm out" is not an excuse, it is saying you are leaving. You don't tell your teacher "I'm out" when you dont do your homework.

Lekgolo, out.
