Yes. Let me explain my situation better. I have a plane for water that is always rendered and is at the same depth (y-value). I also have things like trees that have transparen parts (between the leaves). Most of the terrain is over the water line, so where there is solid ground, I could have a tree. This tree should show the terrain below it where the leaves have their transparency. Instead, I see the water. This means that the terrain is rendered last. I just wanted a way to tell DB to render the terrain first. This would solve the problem.
I have thought of a slightly more complicated (and possibly more costly) way of accomplishing my goal: First, I turn off the backdrop (which I'm doing anyway). Hide/Exclude ALL the objects except the terrain, render, and show/excludeoff ALL the objects and Hide/Exclude the terrain and render again. This would leave the terrain as like the "backdrop" so that the next render would have that show up in the transparent areas..... I would like to avoid this if possible, but it's a shot.
The fastest code is the code never written.
