color material can't display in EDT_DIRECTX mode!

[michael520]

I use 3ds max and make a model of box, giving it a simple color material in the material editor, then export it to an x format file.

Then, I use the Directx Mesh viewer to open the x file and it's display well.
Also, I load the x file in irrlicht with EDT_OPENGL, and it display well,too.
But, when I change the mode to EDT_DIRECTX(8 or 9), the color of the model is gray...(not colorful anymore, lost color)

Anybody here know the causes ? Very emergent~~~
Thanks

Help please...
Why no body reply?

can you post the problem file?

does it work in OpenGL? If so, then it's a problem with DirectX, if not then it's a problem with the 3DS loader.

He stated in his first post that it works with OpenGL, but not with any DirectX. Also, it's not a problem of the 3ds loader, but of the x loader as it's been converted to .x. But this introduces a new tool, so it might be a bug of the 3ds->x converter as well.

I have experienced similar problems (shading working properly for OGL, but not for D3D), so I made following change to D3D renderer:

Code: Select all

	pID3DDevice->SetRenderState(D3DRS_DIFFUSEMATERIALSOURCE, D3DMCS_MATERIAL);
	pID3DDevice->SetRenderState(D3DRS_AMBIENTMATERIALSOURCE, D3DMCS_MATERIAL);
	pID3DDevice->SetRenderState(D3DRS_SPECULARMATERIALSOURCE, D3DMCS_MATERIAL);
	pID3DDevice->SetRenderState(D3DRS_EMISSIVEMATERIALSOURCE, D3DMCS_MATERIAL);

and voila, D3D renderer problem(s) disappeared.

you are using materials not specific textures - try adding a coloursheet texture and UV mapping co-ords then export it - it will then give you the colour on the sheet (needs to only be small).

I don't quite get it!
How to add a coloursheet texture? that needs a picture with color?

but why the directx mesh viewer can't view the color...

Thanks a lot Vox!!! I will try your method later!!

Thanks a lot! The problem is solved!!

Errrm, where exactly did you put this code?
Somewhere within the Irrlicht source like void CD3D8Driver::setBasicRenderStates ?

Thanks,
