My question is - how to create a shading setup that will smoothly interpolate between full opacity to full transparency. I'm trying to do this on a simple plane with somewhat partial results.
In the image above you can see that the rendered image is partly invisible only on the background of a different plane, and not where the scene background is. Is there a way to solve it so that I have alpha everywhere?
What I simply want to achieve is a linear gradient from one color, to a transparency, something like that:
