I want to make an object semi-transparent. I produced a texture, useAlpha_crystal.tiff, that has an alpha channel with 50% alpha throughout. I UV mapped an object, gave it a material, and exported my age. In the output of the export, I can see that it denoted the texture as using alpha. However, when I'm in my age, the object is completely opaque (i.e. not semitransparent).
What should I do to get this to work? Note: the texture is gray scale, so it only has two channels: grayscale and alpha.
