I am loading a texture in the max distance texture slot, not in the occluded or unoccluded texture slot.
What i am trying toi achieve is to use a texture to mask occluded and unoccluded color in order to avoid that plain gradient transition between the 2 colors.
I used to do this in Vray, i used a texture in dirt map but the i could still use the radius value.
Maybe my workflow in corona is wrong.
