I have been trying to create the vertex shader declaration for a simple vertex shader that uses this data: 3 floats in v0 3 floats in v1 2 floats in v2 etc... This is what I have:

  
D3DVERTEXELEMENT9 vertexShaderDecl[] = 
{
	{ 0, 0,  D3DDECLTYPE_FLOAT3, D3DDECLMETHOD_DEFAULT, 0, 0 },
	{ 0, 0,  D3DDECLTYPE_FLOAT3, D3DDECLMETHOD_DEFAULT, 1, 0 },
	{ 0, 0,  D3DDECLTYPE_FLOAT2, D3DDECLMETHOD_DEFAULT, 2, 0 },
	{ 0, 0,  D3DDECLTYPE_UBYTE4, D3DDECLMETHOD_DEFAULT, 3, 0 },
	D3DDECL_END()
};

and it gives me this error when I try to compile it: (2): error X5326: Read of uninitialized components(*) in v0: *x/0 *y/1 *z/2 *w/3 (3): error X5326: Read of uninitialized components(*) in v0: *x/0 *y/1 *z/2 *w/3 (4): error X5326: Read of uninitialized components(*) in v0: *x/0 *y/1 *z/2 *w/3 (5): error X5326: Read of uninitialized components(*) in v0: *x/0 *y/1 *z/2 *w/3 (12): error X5326: Read of uninitialized components(*) in v2: *x/0 *y/1 z/2 w/3 (24): error X5326: Read of uninitialized component(*) in v1: *x/0 y/1 z/2 w/3 (25): error X5326: Read of uninitialized component(*) in v1: x/0 *y/1 z/2 w/3 (26): error X5326: Read of uninitialized component(*) in v1: x/0 y/1 *z/2 w/3 Does anybody know what I am doing wrong? -Greg

thank you so very much. Guh, that is stupid. Is there any way to just set it to a number without using those defines?

You need to specify the offset more then anything. The new declaration type severs vertex streams from vertex shaders - a big problem for DX81 (Hence my handle).
