My Sprite is gone when i render the Skybox
Author
Sorry Guys i feel so dumb today:)
I finally got the Sprite to render the right way.
Now i wanted to put it into my scene but its gone now.
all i do is render the skybox and then the sprite.
do i have to lock the z-buffer or something?
when i do it without the skybox it works just fine

i am doing this before i render the box
m_pd3dDevice->SetRenderState(D3DRS_ZENABLE, D3DZB_FALSE);
and this after
m_pd3dDevice->SetRenderState(D3DRS_ZENABLE, D3DZB_TRUE);
i can see other objects when i insert them just not the PointSprite
m_pd3dDevice->SetRenderState(D3DRS_ZENABLE, D3DZB_FALSE);
and this after
m_pd3dDevice->SetRenderState(D3DRS_ZENABLE, D3DZB_TRUE);
i can see other objects when i insert them just not the PointSprite

Try with:
m_pd3dDevice->SetRenderState(D3DRS_ZWRITEENABLE, FALSE);

i tried that but that didnt help
it might be a diffrent problem though as i just found out something else.
when i put something other than 0 to the x or z position of the sprite it starts moving around which it really shouldnt
here is my code if anyone wants to take a look at it:
could it be something about the way i fill the Vertex-Buffer?

tried it but doesnt help:)
i really think its a general problem with the rendering of the sprite
it really shouldnt move when i set the position to a constant spot:)
i just cant figure out the error:(
