I hate bad fake bumps, but a good one is always awesome.

I guess I hate them, because very few people actually use them right.

i love good fakebumps
no fail fakebumps
+ you are a troll and make an extra thread about that only because i said fakebumps are good

dont care

I just don't understand why bumps weren't implemented in anything but the the BSP. I mean, especially in scenery, If I WANTED to, I could just make all my scenery as part of the BSP if I am not mistaken since it is all about polies rendered at one time on the screen that causes lag.
Would it really have been that taxing on the engine?

Normal mapping wasnt really in use by microsoft game studios until early 2003,H1 was finished I believe in 2001,and H2 came after or on 2003 so thats why H2 has it.

Basically in short wasnt in wide use yet until 2003.

But yeah I do agree but theres nothing you ca do even with fake bump mapping.

never, ever, ever, ever use that fake bump technique that does nothing more than give a blacker outline. it looks like garbage and makes the characters look like they should be cell shaded.

halo does not support bump maps, deal with it and focus on trying to get what's available to look good rather than trying in vain to fake some feature that will never look proper.

That wont entirely work.
The engine will only render 10,000 polies at once, per portal (BSP only)
so, if you put the trees, which are about 1000 polies. You'll only be allowed to have ~5000 polies for the BSP mesh, and 5 trees.

:/

You can't even call it bump mapping really, it's basically a jacked up ambient occlusion map.

Fakebump is bad because it doesn't even bump. What you need to do is make a multipurpose map, like CMT's spiker.

I thought you make a normal, Overlay a bit of it onto the diffuse, then overlay a lot (or all) of it onto the multipurpose? That's what broke taught me to do.

Really the only way to do it right (In my opinion) is a completemap bake with the normal set as a bump. You need to light it properly and tweak it a bunch in order to make it not super gay.

Isn't this the cartoony way to do it?

you all don't seem to understand the purpose of bump mapping.



similar to normal mapping, the idea bump mapping this is to allow for more detailed lighting and depth without using more geometry. it's all optimization.



you cannot "fake" this effect. you cannot cause light to be cast differently on geometry that does not support bump mapping. every time I see a "fake bump" as you call it on a model, it looks like horse balls. if you really want the model to have more depth and detail, just model it in, stop trying to find workarounds to "fake" it, every time I see a "fake bump" applied to a biped, it's usually eye-gougingly ugly

I like how the blood decal in the picture ruins the normal mapping.

That second picture isn't normal mapping, its called a parallax map.

lol, higuy i dont think any of them know what that means(except for dee adn a few other modelers) YAY PARALLAX MAPPING!....no flattening of the surface when viewed from an angle :D

idk just googled bump mapping and grabbed a few pictures that popped up

the ghost has a section on bump mapping i found a while back.i've never really looked into it all that much,but incase someone finds it useful...http://ghost.halomaps.org/tutorials/tuts/bump/intro.htm

Shader_environments support bumping. Unlike other games, halo 1 doesn't do 'model' bump mapping.
Fakebump isn't possible or necessary.

Yeah, but as it turn out, he's right. He doesn't make maps, as I understand, but bump mapping is used in a lot of games.

I hope you didn't mean me in that?

Parallax mapping also known as offset mapping or virtual displacement mapping,use's a regular normal mapping bitmap or image and goes one step further,and use's a height map to further it's details and accuracy.

So basically 2 is better than one :p


And this thread may continue for awhile because theres alot of methods for fake bump mapping,or as noted above^^ horse balls .

Bump mapping has essentially been replaced by tangent space normals. Normals give off a more real time lighting angle to details which technically don't exist. Bump mapping more so throws light in every direction to give the object the appearance of having depth but will give off the crisp, nice effect of having light reflect off of a normal map. Parallax (made from height maps) is nice, but it can look weird when you get in too close because the map is still flat but it gives a super awesome affect of it actually looking like there's depth. Works best on stone.

Tangent space normal


Bump map


So clearly bump mapping doesn't even look good in the first place, why try to fake it? And by "faking" it, what you're doing is creating the shadows that would have been created if a bump map was there and overlaying it into the diffuse. AKA an ambient occlusion map, not bump. Which is actually part of the "next-gen" work flow. If done right ambient occlusion can strengthen your diffuse map.

I agree that normal mapping is MUCH more effective, and almost every form of fake bumping does involve adding an OCC map, but bump maps are effective when used with normal maps, and can be baked into the diffuse to create "good" results.

Every form of fake bumping is compensation, it is never intended to look as good as the real thing. However there are times when it can be applied in a somewhat useful way.

Fakebump = AO

Tbh the only way I can think of "faking" a bump map is by being very clever with the spec-map. But even if you managed to get a good effect you will still only be able to get the "depth" by looking at it in one direction.

I'm no expert on it, and I never said I was. I do however have basic knowledge of it, telling me I don't know what I'm talking about is completely ridiculous, as my point remains valid.

to my knowledge a bumpmap is an image that alters the way light affects a flat surface on one axis. heretics in halo 2 were covered in these bumpmaps, to the point of being extremely excessive. normal maps, while similar, affects all 3 axis and can make a low poly model look much more detailed, as seen in many unreal engine games. I have never heard of parallax mapping and do not know how they work, I agree. you wanna fight about it?

the point remains that you cannot "fake" bump maps, and all of these models that have "faked" bump maps applied all look like garbage

normal maps = real time.
bump maps = render only, they can't be used in real time.

okay, let me restate that since you're getting all agro.

fact: fake bumps don't look like legitimate bumpmaps. therefore, they do not look like what they're intended to mimick. the engine does not support it, and "faking" it does not yeild successful results

opinion: that most of them, huge excessively bold, black outlines, make the models horribly out of place and cell shaded. they look like absolute horse dook, and people need to stop trying to "fake" features that the engine doesn't support, and focus on getting what's available to look good. diffuse maps and speculars. faking features that the game engine does not support is stupid and futile, for the simplest of reasons

don't like my opinion?

Fakebumps / AO looking good is a matter of fact, not opinion. Who is the right mind things they look good.

They only thing that it does is use the normal maps to make an AO as the normals have all of the additional detail information.

You would get better results modelling the highpoly and baking your own AO and then texturing it your self as you can take into consideration that its for an older engine which means you can modify the model/textures to allow for that and make it look better instead of being stupid and ripping content from a next-gen game and put it in an older engine

LOL, "Come at me brah". Please don't attempt to be a hard man online. I ain't even going to bother, pathetic lmao.

Contradiction makes my head hurt.

no. look at the biped's thread. everyone in there thinks their fakebumps look good. what looks good to one person does not to another. good and bad is subjective. good and bad is opinion



I said the same thing on the last page. u got eh problem bre?



I just admitted that in my last post, or can you not read

also, win/lose? oh, so it's some sort of contest now? well, I'm glad you won, go ahead and frame your e-victory and put it on the wall above the fireplace for your kids to see

lmfao, i dont have an alt account. I have one.

I think you have angst. How old?

Who's Floyd? Google shows no Floyd related to halo. Did he get banned from this site or another?
