Hi,

can someone of the shader-gurus change this multitexturing code to a dx9 compatible version ? I think the original is from stempie or ventilator ...

Code:

Nobody ? It is the shader from the wiki :
TerrainMultitexturing

Texture[0]=<entSkin1>;
Texture[1]=<entSkin2>;
Texture[2]=<entSkin3>;
Texture[3]=<entSkin4>;
MagFilter[2]=linear;
MinFilter[2]=linear;
MipFilter[2]=linear;
MagFilter[3]=linear;
MinFilter[3]=linear;

VertexShaderConstant[4]=<matWorld>;
VertexShaderConstant[8]=<matWorldView>;
VertexShaderConstant[16]=<vecSunDir>;
VertexShaderConstant[20]=<vecFog>;

some of this stuff is case sensitive now and you have to remove the .x of oFog.x. these are the errors i noticed at first sight but there might be some others. what do the error messages say?

Thx venitlator. The error is :

the () of the shader constants have to be changed to {}.

Thx a lot! It works fine now ... Small thing, but big error.

I tried to use the shader but got an error message.has anybody an idea what this means???

I can´t get this multitex-shader to work. My code:

I´ve got this error:

Malfunction W1550

Error in Effect:
mat_terrain_multitexture(78):error X3000:syntax error:unexpected integer constant

The debug syntax check found no error, can anybody help??

some errors :

use

vertexShader=

asm
{
vs_1_1
dec_position v0
dec_normal v1
dec_texcoord v3
dec_texcoord v4

instead of

vertexShader=

dec_position v0
dec_normal v1
dec_texcoord v3
dec_texcoord v4


asm
{
vs.1.1

there may be more errors.

For both the ps11 and ps14 code you posted...

Change the stream declarations from this:

Quote:

---

vertexShader=

dec_position v0
dec_normal v1
dec_texcoord v3
dec_texcoord v4


asm
{
vs.1.1

m4x4 oPos,v0,c0 // transform position to clip space

..........

---

To this: (Note the location of where the declarations go now.)

Quote:

---

vertexShader=

asm
{
vs.1.1

dcl_position v0
dcl_normal v3
dcl_texcoord0 v7

m4x4 oPos,v0,c0
..........

---

And in your ps11 code, change <oFog.x>, to <oFog>. Just like you have in the ps14 code.

And as pointed out, change the <vs.1.0> in the ps11 code to <vs.1.1>.
