Material.Transparency

Description

What type of transparency does this Material use? Default is None. Transparency has an impact on performance, and draw order. Check the Transparency enum for details.

Examples

Additive Transparency

Here’s an example material with additive transparency. Transparent materials typically don’t write to the depth buffer, but this may vary from case to case. Note that the material’s alpha does not play any role in additive transparency! Instead, you could make the material’s tint darker.

matAlphaAdd = Material.Default.Copy();
matAlphaAdd.Transparency = Transparency.Add;
matAlphaAdd.DepthWrite   = false;

Alpha Blending

Here’s an example material with an alpha blend transparency. Transparent materials typically don’t write to the depth buffer, but this may vary from case to case. Here we’re setting the alpha through the material’s Tint value, but the diffuse texture’s alpha and the instance render color’s alpha may also play a part in the final alpha value.

matAlphaBlend = Material.Default.Copy();
matAlphaBlend.Transparency = Transparency.Blend;
matAlphaBlend.DepthWrite   = false;
matAlphaBlend[MatParamName.ColorTint] = new Color(1, 1, 1, 0.75f);
