   D3DXMESH vertex color changing
  Hi,Is there any way to change vertex color in a d3dxmesh loaded from an x-file?After some experiments I've figured out that the vertex are in fvf as below:XYZ|NORMAL|TEX1and these are the only things I can change right now. But my app uses dynamic lighting and that works on per-vertex basis (I guess xyz and normal are enough) so vertex colors got to be somewhere. Where? And is it available for me?Or maybe I have to make my own vertex format with color and convert the mesh's vertex buffer to it?I need access the colors directly (I have to find the time to learn those famous shaders ;-) ) to implement a simple shadow system. I know there are better methods but I'm trying to understand all this a little deeper.ThanksBartiss
