Ok, I suppose that bump-mapping is a method them makes textures look 3d right?? Correct me if I'm wrong...

Since I'm interested in this kind of technology for CIM, I would like to know if any kind of program or technique is required in order to make bump-mapped textures... or does the engine make that for itself???

You will usually want to make the bumpmap texture yourself, also you may need to make an environment map.

[Raven2001]

How do I make that bump-map texture?? Any special prog for that??

[RandomTiger]

Its nothing special, just a greyscale pic showing the height.
Do some searches on google.
DX8 SDK has some examples as well.

[Ryx]

Here's an exsample.


*hopes the bump effect is visible*

[Fury]

It is visible.

Bumpmapping would be neat for TBP...
(and for any other project for that matter )

[Taristin]

Yeah, but I wonder how smoothly the game'll run. We all want large texxies, and bumpmapping, who cares if we get a 2 fps rate?

[RandomTiger]

I figure we run it through hardware using DX8 and those who have cards that can handle it will be OK and people who cant just wont have it.

Will a GF2 Mx 200 support it?

Well, me GFMx200 supports it in other games.  although I'm not sure how much impact it would have on FS2, based on the fact I've never noticed whether it's in I-War2 or not.

[RandomTiger]

Dont know, given that its an MX perhaps not.
To be honest I know very little about bumpmapping in DX, just that it is possible.

well, as Iwar2 doesn't have bump mapping, you'll never notice it Iwar2 has reflection maps.

Hmmm... I got it

Thanks everybody

BTW, if I make a bump mapped texture and use it in FS right now, nothing will happen, but the game will run normaly right?? Just think in terms of testing stuff now, without having to make a texture redesign...

Again I beg you don't make the bumping DOT3. pweeez, otherwise my little G400 won't run it.

[Bobboau]

you can't make a bump maped texture now, we don't even have a way of entering the data yet

We really arent at the stage yet but personally if I was on the job I would do it the quickest and easiest way. That would probably be using the hardware support DX8 allows.

What sort of performance hit would we be looking at with bump mapping, anyways?  It's pretty intensive with the lighting, isn't it?

I'm not sure how effective it would be for the cost, that's all.... I'm not sure how many people can actually do GOOD bump maps - I know I can;t (just use embossed maps..hehe).

If its going through hardware it should be OK and as long as its optional then no-ones going to suffer a slowdown they dont want.

[Raven2001]

Take your time to do it... I'm not in a rush

Again, if you ever need a modding hand in terms of tables or models, feel free to ask

[EdrickV]

I have a very basic idea what bump mapping does, (D3 does something similar to create terrain levels from tga files.) but what is the difference between applying bump maps directly to the textures in a graphics editor as opposed to applying bump maps to the textures/models on the fly?
