Hi all,

I don't know if this is the right topic for the advanced forum. I have an existing terrain-mesh modeled in max and exported to a directx-file. I want to use the cool grass node system presented by bitplane and tried to create a heightmap from my terrain.
So far i have written the height of ...

The preceding code worked for me when I modified the existing material EMT_SOLID_2_LAYER inside the CD3D9MaterialRenderer.h. Now I tried to add my own material to the materialtype enumeration, modifying the following files:

SMaterial.h
CD3D9MaterialRenderer.h

Afterwards I recompiled the source and ...

I think that the vertexalpha blending mode in the second layer only accepts two parameters or colorargs, first one is the result from layer 1 (texture 1), second parameter is the texture from layer 2, blending mode vertex alpha. If I wanted to add dynamic lighting (shadowing the blended two textures ...

Got it, adding a third layer helps: :D


pID3DDevice->SetTextureStageState(0, D3DTSS_COLOROP, D3DTOP_SELECTARG1);
pID3DDevice->SetTextureStageState(0, D3DTSS_COLORARG1, D3DTA_TEXTURE);

pID3DDevice->SetTextureStageState( 1, D3DTSS_TEXCOORDINDEX, 0);
pID3DDevice->SetTextureStageState(1, D3DTSS ...

Ok, I have investigated a bit and it seems quite clear to me now:

The first texture layer of the material uses the following params:

pID3DDevice->SetTextureStageState(0, D3DTSS_COLOROP, D3DTOP_MODULATE);
pID3DDevice->SetTextureStageState(0, D3DTSS_COLORARG1, D3DTA_TEXTURE);
pID3DDevice ...

Hi,

I have looked into the source code of the file C3D9MaterialRenderer.h and wanted to modify the shader properties for the material EMT_SOLID_2_LAYER. I want to have the material being lit by dynamic light. By default, the material ignores the material flag EMF_LIGHTING = true. The material ...

Thanks . Perfekt.

Thanks hybrid, this is really good. It works, I switched the one light off with the following code:

lightData.DiffuseColor = SColorf(0.0f, 0.0f, 0.0f);
lightData.AmbientColor = SColorf(0.0f, 0.0f, 0.0f);

So if there is simpler code, like a flag for visible or not, please tell me, I didn't find any ...

Sounds good, thanks, and it works . The only thing I try now is to chnnge the vertex colors from white to black, because switching EMF_LIGHTING to false lights the model with the vertex colors(?). Or am I wrong?

I want to have cheap shadows for my bicycle model and so I created a camera fixed to the sunlight that renders the bicycle model in a second render pass to a texture attached to a plane below the bicycle. But the rendered image is colored and sharp (naturally :). The shadow plane has transparency as ...
