dx lighting and tris

Heh nice example ross.. hmmm sadly though i get quite a diffrent effect when using this approach.. This is odd... Gonna strip out some stuff until it works then start adding back in until i find out whats causing it..

Also, im sure this has been covered... EntityAlpha() on meshes set to use vertex coloring (entityfx mesh,2) dosent work.. its either all the way on or all the way off. Im sure its because setting fx 2 truns off alphablending ?

Try ross's example with enityfx command remed out, then try it on..

Function rotate()

	VertexCoords(surf,1,	Cos(angle+180),	 1,	 Sin(angle+180) )

Ross, thanks.
Sswift, thanks.
