View Full Version : Using shaders in ArmA
Hi all, maybe you already know that but since there isn't a topic about this i decided to share with you some things i discovered...
First of all i was trying to convert some old addons i did for OFP to ArmA and i was searching for a way to implement normal and specular maps on my models so i took a look at those new rvmat files. Since without the proper tools we are unable to use them as they are used directly by the p3d i began searching for another way. I remembered the old cfgTextureToMaterial that we were using in OFP to add shiny effects on our models and i noticed that some new materials in ArmA do look exactly like the rvmat files. So i tryied to do my own material based on the Javelin rvmat file and i tested it over a BIS LAW model imported from ofp. Here's how it looks like with a fast normal map done with nvidia plugin for photoshop.

And here's the code to add on your config:
Note that you'll have to recalculate normals on your p3d

textures[] = {"LAW_TEST\law_side.pac"};

pos[] = {0.000000, 0.000000, 0.000000};
};
};
};
};
I'm not going to release this as it was just a test to see if it was possible for us to use normal maps before the official tools are released. Hope you found this usefull.
Woh, that looks pretty good for a 2001 model. Cheers! http://forums.bistudio.com/oldsmileys/biggrin_o.gif

another thing that might come useful: by adding a point in the memory lod with selection name "eye" in the position where the eye should look it is possible to use 3d optics on custom addons.

I never understood why they said that my texture count was low when I said I have 3 textures on a large plane.
Then I opened up another addon to discover that it has 4 textures for the fuselage itself.
Ineffective uvmapping IMO.

You can't do much in Oxygen. You can limit texcount with texmerge function but their uv mapping is still bad http://forums.bistudio.com/oldsmileys/sad_o.gif. Hopefully the new Oxygen has a better solution http://forums.bistudio.com/oldsmileys/smile_o.gif.
But there are other, better, free applications, such as LithUnwrap. You can use a p3d2obj converter or p3d2ms converter and unwrap it there, ofcourse merging the model into one large group first. Then you can import it back to o2 via the 3ds importer.
New objective have unwrap function, but in old texmerge you still can merge textures, generate ptm file and load this file to O2, that will autamaticaly merge textures in all lods by definition in ptm file (this also posible in o3 - new objective)

how good is this unwrap function though? http://forums.bistudio.com/oldsmileys/tounge2.gif
Its basic unwrap, main advatage is that u dont need to go back to max to maya if you want something remap, another good think is that it support multiple UV sets, so u can for example separately unwrap normal map or macro map with diferent UV in diferent layer from one material.

aaah, that sounds good - I wasn't looking forward to having to learn unwrap in 3dsMax for the sake of modding in Arma, so this sound much better (assuming its easy enough to get to grips with)

that's what oxygen was missing http://forums.bistudio.com/oldsmileys/biggrin_o.gif can i ask you how are the new shadows handled in the p3d? I've been trying to make them work but without success. My guess is that there is a new lod dedicated for shadows but i'm not sure about this. Also i noticed that now weapon models do have "component" selections but i can't figure out in which lod and for what purpose. Is this related to shadows or to some other feature?

There is a new LOD, you can use it in O2 lite by creating a new LOD with resolution of 10000. In it should be the model used to make the shadow volume, it needs to not have any holes in it (O2 lite 'structure/topology/find non-closed' can be used to find these) and it must be made of only triangles... If the shadow LOD is incorrect you get a whole bunch of warnings in the rpt file.

Its little bit complicated, we can use 3 diferent kind of shadows. From original OFP u know CPU shadows, they are now used as hybrid shadows for vegetatin and they are casted on lanscape , when stencil shadows are casted on objects. Hybrid and stencil shadows are used when shadow detail are normal or lower, otherwise shadow buffer shadows (SB) are used. CPU shadows are same as was in OFP, stencil shadows use special lods as Kegetis wrote and there could be more stencil shadow lods with diferent detail. stencil shadows must be triangulated, must use sharp edges, model for shadow must have volume (must be closed). SB shadows have also special lod number and could by normal model (simplified), its good if have just one section, not using any materials. There must be property in geometry lod that will say what kind of shadow lod in what situation will be used. We will add full documentation to biki.

I wonder if it would be possible, then, to create a flir script that applies different shader and texture properties to models, to make them lighter in colour than the background. This. in combination with the apperture script might make some clever flir images.

Please excuse the noob question... So how would one go about creating this 'shadow volume'.
As per Keygety's quote above I obviously create a new LOD with resolution 10000. Yip got that.
Is this new LOD a copy of an existing LOD that is modified?
Or, is it a completely empty new LOD?
And, what goes in this LOD, specifically.
Is it an abstract of a more detailed LOD that is offset?
Basically I'm asking - How do I create a shadow LOD in O2 for an MLOD so as to bring it on over to ArmA?
Oh, and yes I did do forum searches for 'Shadows' and 'Shadow Volumes' prior to posting without significant hits.
Links or any info. to get me running in the right direction would be appreciated.
Cheers, Sy.
PS. On a slightly related topic... Anyone want to collaborate on deducing version 40 please let me know.
PS2. Oh... Keygetys... I can understand the relative ease with which you may have guessed or deduced a 'Shadow Volume LOD' was needed.... But, how on earth would you devine that it needed a resolution of specifically 10000?
just make a version of what you want to be "shadow", and be sure to use tringalate and after you done that be sure to reverse the model (Press W).

It's a specular map with higher bit depth apparently. Regular spec map I'm familiar with, but this I don't know what tools there is for. Anyone know?
Also, I'm having some glitches with a normal map. It's sort of flickering between on and off when moving around.
Here's how it looks on my model, top one is with and the other without normalmap. It changes depending on which angle it gets lit.
http://img129.imageshack.us/img129/6585/ak51gd8.th.jpg (http://img129.imageshack.us/my.php?image=ak51gd8.jpg)
Anyone know what's going on? Is it because I don't have a smdi yet or is it texture compression?
i have a similar bug on my law although is less noticeable, i think that it's caused by the missing swizzle tag on our textures.
If you open a BIS normal map file in photoshop with Kegetys tools it will ask you if you want to apply swizzling.
I think it changes the way how Normal and Specular maps are handled by the engine. But of course i may be wrong, this is just a guess.
As for specular maps, i created a new file in photoshop with the background color value taken from a BIS specular map. I then added a new layer with my texture and modified the blending mode (i think to Highlights) so that only scratches and texts will be seen on the specular with white color. I don't think this is the right way of doing it but i guess that without some kind of tools it can't be done otherwise.

just a question, but is this the way i should do my Normal mapping, by adding the huge section inside my CFG for every object that needs the normal mapping... The reason why im asking is that I am about to start adding the Normal maps, and I have almost 140 objects that will get the BUMPmapping/normal maps.
I would like to avoid my CFG becoming a potential nightmare.

Yes you have to do it for every texture that will need a normal\specular map. I think you should wait for some tools that will allow us to write materials directly in the p3d files and using the config way just for testing purpose

I think you just overbrighted the specular map - make the "shining" parts a bit darker (i haved similiar problem), but i may be wrong http://forums.bistudio.com/oldsmileys/confused_o.gif
As it seems a lot of you are experimenting with this i've decided to release the law in the state it is now.
I haven't worked much on it since my last update as i didn't have a lot of time. Actually i think that the model should be redone with more polys especially for the tube, but it's just pointless doing it now, i just tested what i needed.
So if you want to take a look on how i did it here's a rapidshare mirror for the file.
http://rapidshare.com/files/23251398/IND_LAW.rar.html
Special thanks goes to Freshman that provided me reference photos of the tube and the sight texture i'm currently using.
Remember that this is alpha version, unfinished and with several issues, should be used just for testing purpose.
I'm getting dark spots on with the 'fake' smdi map no matter what. Anyone got regular specular maps working?

Hello All,
I've tried Indy's config and ok it worked. But I was able to define only one material, so how can i define 2 or more materials eg. metal and wood? I have tried many ways to write it in right config but write me error if have 2 materials defined. Sorry but my lack of knowledge of writing configs is limiting for me.
So again mz noobish question - can someone post working part of config with 2 or more materials defined with Indy's CfgMaterials.

Thats the code for my M4A1s to test out the normal maps etc. Also, for the SMDI file,s I just used a pink layer (colour code: ff29ff), with 90% opacity, blending it with only the red and blue layers (not green), so it worked quite well.

do you have a specular texture? (greyscale specular texture)

Here is the texture colour map:

Yesterday i've looked in the MechaStalin's BMD-1 textures and when I opened his specular or normal textures in PhotoShop it asked for that Swizzling (wtf is that btw?) like original BIS textures. How can we do it that way? It would be great if he (or someone that knows lot about this) can share his knowledge with us.
Thx

Oh and one another question - do you guys using the color map (like that nice Jackals above) for creating normal map with nvidia filter or you create new grayscale texture and then you applies nvidia filter for creating bumps?

@<hidden> why do use a color map? you just need a normal map and a greyscale specular map (to make the lights on your object).
Quote[/b] ]do you guys using the color map (like that nice Jackals above) for creating normal map with nvidia filter or you create new grayscale texture and
no and no, you can't use a simple greyscale texture to make a normal map. you need to draw with grey, black, white colors the details of your textures (bolts etc). then you can use the filter. a normal map must no have colors.
quick example:

pic1-- greyscale bump texture
pic2-- normal map (i use the nvidia filter)

The nvidia tool converts bump maps to normal maps. A bump map is a map that provides height information in a colourless gradient. Black = Low and White = High. So, for best effect, you would redraw everything so that stuff gets lighter as it gets higher, then convert it to a normal map. The preferred method for normal map generation is to use a high poly model for normal information and apply it to a low poly model.
There are tuts out there that tell you all about how the 3 colour channels work for a normal map and how to effectively edit them, but I can't seem to find them again. If you want to edit a normal map by hand, you'll have to look around a bit!

no, the two methods are great, because each can be use use for different things.
example: the high polys method is excellent to create a character, but if you need only bolts on a hull, the bump map method is the easy way. http://forums.bistudio.com/oldsmileys/smile_o.gif

True enough, however, given that the hull is probably a more complicated shape than the poly limit would allow for, I, personally, would still generate the high poly model. I would not model ever bolt and screw, though. For that, I would edit the map I generated later. That's just how I roll.
