Blurb A simple shader

Detailed description

Pretty selexplainitory, it looks like a comic book.

Some side notes (if you cant read shader code):
- Only effects models (maybe do textures, etc later)
- This is just a simple edge detection formula, (all credit goes to the four or five wiki pages i referenced)
- Effects all models(mesh, not always the entire model) that have evnmap(md5envmap), mask(md5mask), and normals(md5bumpmap). If you do not have all of these set then the model will not use the code :)
- I had to add md5env maps to inky and captaincannon, if you dont put these new md5.cfgs in, then they will not render (see note above)
- Doesnt work for orgo (hes too old, and lacks the maps needed)
- This formula can be simply modified to make a vary of effects :) the general formula is:
if( dot(camdir, normal) (less than) mix(minedge, maxedge, max(camdir, normal){
colorout *= newcolor; //usually a percentage
}

doing this multiple times causes cel shading, setting newcolor to 0.0 makes an outline :) petty simple. You could add rim lighting with this as well.

Ps: this may be in the new sauerx release

Preview

we realy need to fix the tag error, cuz its the same as the greaterthan sign :)

see code on lines:1164-1181 of glsl.cfg :)

Try the plain text format(at input settings if you use certain symbols within your node.

There is no glsl.cfg included =S.

ooops i forgot it i guess

and meh plain text means you cant do bold and all that shit ;) maybe u should just fix it :)

Seems to work just fine even without the plain format setting.

Too bad the hudgun isn't cartoonish as well.

ps thanx suicizer for puting the > the wrong way :) lolz that code would force things with a hight dot value to return this color -.- aka things that are more directly in line of the camera (like a specular would -.- fail)

Greater than is > under normal conditions in mathematics, which you stated first...

For your information, an admin or moderator editing your node is certainly not abusing powers as that's the role of admins and moderators; cleaning up the mess which users leave.

Now what if you and chase switched positions? You would probably say the same thing :P

But otherwise, sexy shades @chase.

cant you just add exec custom.cfg to the existing glsl.cfg?

Chasester_aka_you | 2014-01-22 00:17

not the way its set up

you can only define a shader by name once. this is a macro (well technically a function) that is used by ever model shader (weither it be stdmodel or bumpenvparllexworld) all the models run through this fragment shader.

So the only way to get this to work otherwise (and this would be really hacky), is to define my own shader, some how receive in the variable shader buffer information (world vec for normals, and cameradir for camnormal). Then i would have to put setshader "shadername" in each of the models md5.cfg files. SUPER HACKY.

Shaders are not something you turn off and on, you render a model with one or maybe two shaders, (and if you do add more you are just stacking them).

Any way so the simple answer no it is not the correct way to do it.

@hudguns models etc
if you want your hudguns and models to use the shader simply add md5env "mesh" socksky/mars - to there cfg files and when defining the skin set the last two parameters to like .4 or .5, you can play with it a lil. The way the buffer is being passed it will not work right if you just simply allow models without envmaps to work. (this would require a code change, if its even possible).

Im sure this would take maybe 20 mins to fix, but im not thoroughly familiar with the ins and outs of the hugguns, and playermodels etc

I only adapted this for cube because i was writing it for something else any way.

Looks cool. Not much to say about it, I didn't even know that there were shaders in Sauer until recently :p
