Defferent between Vertex & Material Alpha Blending

Recommended Posts

I am a newbie in DX. And I think Vertex & Material Alpha Blending both are Vertex level alpha blending, and texture Alpha Blending is texel level. What''s the difference? And when to use it?

Texture alpha gives you per-pixel alpha
Material alpha gives you per-material alpha (groups of vertices)
Vertex alpha gives you per-vertex alpha.

Which to use depends on what you''re trying to do.

Texture alpha for example is generally static, you wouldn''t want to be editing that dynamically (usually).

Material level alpha only works when lighting is enabled, but is an easy way to control the transparency of an entire object (or subset of an object for multi-material objects).
