In patch4.txt there is written "If you keep your mesh FVF format the same across your 3D geometry, you will notice even greater speed gains."

So when or how the FVF format is the same with all objects I use?

FVF is the Universal Shader Format (essentially)... and unless you understand shaders it is best to not worry about them for now.
If you do understand shaders then the question wouldn't have been asked (^_^)

Raven: What really worries me is that in DBPro I never know when models need normals or not. In DBC they didnt need but in DBPro I have to supply all my models (300 pcs) with normals to get lights to be seen right. And sometimes 'Set normalization' is needed also. So I thought this FVF had something to do with these normals and lights...

Universal Shader Format ???????? what that's invention ???


FVF stands for 'Flexible Vertex Format', and deals with how the 3D objects datas ( being vertices, faces, normals, or else ) are managed into memory !!!


Shaders have relations into this ...

that is essentially how DarkBasic Pro is using them, rather than using the standard Shader format - it uses FVF for import (which i can't stand to be honest)

and it does edit the data on the Mesh, but it does it as a Shader does - so yuo setup the positions on a time scale.
what i'd do is setup a fast-phong shade routine in the FVF ... it should fix your normal problem

there's a good one on gamedev.net
