[Closed] Passing per object data to DX9 materials?

Oct 31, 2006 11:04 pm

Is it possible to pass custom per object data into DX9 shaders, and then setup the shader to read this information?

For example each object will have a unique texture related to it. I would like to pass this texture path into the shader. Then the shader will use this texture in the shader to give each object with the same shader a different look/texture.

Hi Gibbz,

I think it’s only possible to do that with the SDK.

I think the best solution is to create a different DirectX 9 shader in MAXScript for each object and setup a texture bitmap parameter.

For example, if the texture is declared as this in the FX :

texture g_ DiffuseTexture <
  string UIName = "Diffuse Map";
  int Texcoord = 0;
  int MapChannel = 1;
>;

You can set the value for this shader in MAXScript like that :

dxshader.g_ DiffuseTexture = DiffuseBitmap -- DiffuseBitmap is a bitmap value
