the simplest solution would be to just add a constant for the light color in the pixelshader:

Code:

---

PixelShader= 

asm

{

  ps.1.3

  def c0,0.3,0.3,0.9,1.0 // light color rgba

  tex t0 // sample colormap

  tex t1 // sample normalmap

  dp3 r1,t1_bx2,v0_bx2 // normal . light

  mul r1,r1,c0 // modulate light intensity against light color

  mul r0,t0,r1 // modulate light against color(t0)

};

---

(i haven't tested it! instead of mul r1,r1,c0 you could also try mul_x2 r1,r1,c0 or something like that...)

if you want to pass the color from outside of the shader it gets a little more complicated. i guess then you would have to pass it first to the vertex shader and from there to the pixelshader...

yup thast what im trying to work on..
im trying to take vecDiffuse and use to effect the vertex shader and somehow pass it on to the pixel shader.. but i just dont understand enough to do it. I dont get how it knows where to make the light a pure white value.. and how you can change that... i assume you have to put a "mul r0,-r0,c[vecdiffuse]" or something

in the vertexshader you have to define vecdiffuse:
VertexShaderConstant[18]=<vecDiffuse>;

you can output vecdiffuse to oD1 in the vertexshader:
mov oD1,c18

and access it with v1 in the pixelshader:
mul_x2 r1,r1,v1 // modulate light intensity against vecdiffuse

for some reason i cant get vecdiffuse to pass the rgb values..
however.. you can use vecLight.. that does it

thnx a lot for yor help vent..

now im going to try to add a specular component..

can you describe how you assign multiple skins in Med?
I opened my model, with standard color map...then open skins, import dot3 skin and add the skin after the first...is that close?

yes, close!

if you open med's skin editor you should see your color map.

then do the following:

1. edit -> add new skin -> after last skin
2. switch to the second skin with the <next skin> icon
3. import your normalmap - it doesn't matter if you adapt the skin vertices or not
4. edit -> convert skin -> add mipmaps
5. save your model

normally information about which texture you are currently looking at should be visible in the statusbar. but there is a bug in the current version of med...

excellent, thanks. works great! very bumpy

screenshot please!

hey vent.. anotehr question
currently the shader doesnt respond to dynamic lights.. do you know how to add that? also you have any iea why veclight works but vec diffuse doesnt?

vecdiffuse probably is 0 0 0 0 by default?

you have to find the nearest dynamic light yourself in your entity action and pass it as skill41. i guess the upcoming <new light management> will handle this a lot more convenient...
