Can someone tell me what is wrong with my current haybale shader? I can't get the edges to look proper. I have attached the model files also.
This is what is currently looks like in world.


Code:
mtl_haybale_
{
qer_editorimage models\mapobjects\haybale\_haybale_side_nrml-gggr.tga
qer_editorimage models\mapobjects\haybale\haybale_side.tga
q3map_forcemeta
q3map_nonplanar
  cull none //disabling culling (show back and front)
nopicmip //The image will always be high resolution.
{
map $lightmap
rgbGen identity
}
{
map models\mapobjects\haybale\_haybale_side_nrml-gggr.tga
blendFunc filter
rgbGen identity
}
{
map models\mapobjects\haybale\haybale_side.tga
blendFunc filter
rgbGen identity
}
}

Thanks!!

Try "alphaFunc GE128" for transparent TGAs. If you could attach the compiled map, I could test it and post the exact solution, but now I'm just guessing.

Thanks, I really need second eyes on this one. I have tried a couple of combinations but I'm not getting the results.
I am just using a simple map so it compiles fast so I can view the rendering. I have tried the "alphaFunc GE128"  but not looking right.
attached are all the files.

Here's the best result I could get with modifying the shaders:


Some sides are perfect, like the top, but some sides have dark parts. There are less dark parts if only the front sides are drawn, so I guess the 3D model has some overlapping polygons. I don't really know, I'm a noob at modelling.

Here's the shader definition:
Code:
mtl_haybale_
{
        qer_editorimage models\mapobjects\haybale\haybale_side.tga
        q3map_forcemeta
        q3map_nonplanar
        cull front
                {
                        map models\mapobjects\haybale\haybale_side.tga
                        rgbGen identity
                        alphaFunc GE128
                        depthWrite
                }
                {
                        map models\mapobjects\haybale\_haybale_side_nrml-gggr.tga
                        rgbGen identity
                        blendFunc filter
                        depthFunc equal
                }
                {
                        map $lightmap
                        rgbGen identity
                        blendFunc filter
                        depthFunc equal
                }
}

Udi,
Thanks. Awesome job. That will have to do; much better then it was.
I appreciate the help, I was worn out trying to figure that out.
