Light not going through glass

Hi

I have a glass mtl applied to a shelve with a light above it. In the mlt I have effect alpha and effect shadow checked. Why does the light cast a shadow down from the shelve and the light not going through the shelve?
Help please :frowning:

Is affect alpha turned on in the glass refraction group?

affect shadows should work. in case it doesn’t (but again it should), you may try unchecking cast shadows in object properties.

I’ll try that.

the glass’ fog is too thick?

how do I make the fog thinner?

with multiplier…try setting it to 0.01
