Did you put the material alpha value at zero? (just under the RGB sliders on the materials panel).

no i don't

If you dont put that setting at zero your material wont be transparent, even if you turn on raymir.

Hope it works

several things with your materials. You're not getting them transparent because you haven't clicked "mirror transp"-"raytransp" which is what enables transparency. No need to put the material alpha value at zero. Your IOR (1.5) is ok. In shaders, your spec must be 0.50 and your hard 30.
Finally, check Radiance's blender tutorial, it's all explained in detail there:

hi dems,
The top normals of "I" and "X" are going the wrong side, they have to look outside... on "X" mesh i was able to correct this with "Edit / Normals / Recalculate outside" but the "I" mesh is completely corupted. I supose you better rebuild the "I".
