Mental block on simple FVF stride problem
Author
Hello,
Here's a noob question!
Direct3D9: (WARN) :Stream 0 stride and vertex size, computed from the current vertex declaration or FVF, are different, which might not work with pre-DX8 drivers
This error is being output by my lens flare rendering code.
Heres the relevant parts:
I can't for the life of me see why this generates the abouve errors. The stride seems okay to me :(
I am right in thinking the effect file used can't generate this error?
Thanks
Simon
D3DFVF_XYZ is a 3 component vector. You have a 2 component vector in your structure. 2*4 = 8. D3D is expecting a stride of 4 (4 for size of a float) more then what you give it
