alpha + casting shadows

[brunomartelli]

Is it possible to get an alpha channeled material to cast a shadow? I have some trees, with billboard branches - the trunk casts a shadow as does the billboard, but as a solid sheet.

thanks

Your material has to be set to blend_mask (not blend_translucent) and the light should be set to 'bForceDynamicLight - False' 'CastShadows - True' 'CastStaticShadows - True' and 'ShadowProjectionTechnique should be set to something other than ShadowProjTech_Default, I find that _PCF is the best but _low does a good job with frame rate.

As of now static mesh can not cast shadow through an alpha. You have to convert the object to a mover or interp actor.

On a semi-related note, how the hell do I import a TGA with an alpha mask into UT3 UEd?
Tried numerous combinations of settings to no effect :\
