I am using Blender as the 3d asset creation suite for my projects. I have an exporter that is able to export mesh, materials, animations and skeletons.

In my home-grown engine, I want to render some materials with alpha blending. Specifically, I with to be able to set one of the Porter/Duff operators to the materials.

Is there a way I can set this from within Blender? All I can see is a tranlucency adjustment under material properties.

Is there a settings for alpha Blending mode? Or should I use custom property?

Thanks in Advance, -Valyannan.

The Blend Mode in the material settings is only available when Render is set the to Blender Game:

For textures there are Blend types which are also available in the internal renderer.

I'm not sure whether you can map these properties to the required operators defined by Porter-Duff, thus custom properties could be a good alternative.
