Lighting distorts my vertex
Author
Hi there i am having a strange problem. Whenever i try and apply lighting to scene, it completely disrupts my triangle. (it looks like a leaf that was eaten by a caterpillar!)
Does anybody know whats wrong?
EDIT: Please remember to use 'source' tags.

Alright, so I still cant get it right. I have tried looking for an answer all over the net!
Here is the latest code i have tried and a picture of what the problem looks like.
The lighting appears to be working, the triangle is yellowish, but its still scattered and dissolved, what could be wrong?

OK update:
I have discovered that lighting has nothing to do with my problem. It is when i try to use the autodepthstencil that my triagle primitive goes through the meat grinder, otherwise it works fine when i disable it.
For now i can carry on, but when i need to start using z-buffers, this is going to be a big problem.
Any one got any ideas as to what the problem is?

You need to clear the depth buffer as well as the backbuffer. In C++, this is done by passing D3DCLEAR_ZBUFFER | D3DCLEAR_TARGET to IDirect3DDevice::Clear(), I imagine the C#/VB equivalent is similar.
