Set the transparency to 99%, or .99.
Use a Refract node to find out what the transparency is revealing. Make whatever you want for the shader (diffuse, specular, etc.) and add those up. Subtract the Refract node from that. Multiply the result by 99 and plug into Alternate_Diffuse.
You now have a material that acts very close to transparent but in fact is opaque. It will block your view, but not block light (i.e. will not cast a shadow).
In the case of lashes, you also want to honor the transparency map, which means to control where you apply the (diffuse + specular - refract).
Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
