I'm trying to take a vertex/index buffer and save it as a .x file. Is there any easy way to do that? I am not using FVF and am using Vertex Declarations that are explained in the DX9 SDK. When I looked at the docs I seen no way to do it easily but I might have missed something. Or if someone has done it before, maybe they don't mind sharing? Thanks for any help. I'd rather not calculate the 67000 polygons from scratch every time. I'd rather just save it without calculating the normals, etc every time.

Hi there JoeyBlow2, How are you doing buddy?

The Problem
Saving mesh/vertex buffer information to a .x file.
The Solution
Once again DirectX comes to the rescue with a interface called ID3DXFile.

So what you need to do is read on how to create the ID3DXFile::CreateSaveObject() which will help you to save information to a .x file :)

I hope this helps buddy.
Take care and if you have any more questions do not hestitate to ask.

Thanks guys. I'll take a look at those approaches and see what I can do.
