I have a drawing with one plane above another. When I look down on it in Sketchup, the opacity of the material chosen for the top layer allows me to see objects on the layer below. This is how I want to present it. However, when I select the same scene in Layout, the material (standard water) is completely opaque and masks everything below it. Normally, things in Sketchup are pretty WYSIWYG but not in this case.
Does anyone have any idea what I might be doing wrong?
