The Poser "Transparency" effect cannot bend light, nor color it. If you wish to make a material that colors (tints) the light seen through the surface, or you need to bend the light rays, you have to use a Refract node.
But you run into a problem. A transparent material will not cast a shadow, but a refracting material will cast a shadow. So how do you refract without casting a shadow? You need to use transparency but that has the wrong information coming through - it is not colored and it is not bent. How do you get Poser to not cast a shadow and not show the straight transparency, either?
The attached render shows two squares. The one on the left is just using a Refract node, tinted by a light blue color, with some bump to vary the bending of the light. But it casts a shadow. How do you make it behave like the one on the right?
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)
