this is an old subject, but I searched it and only one thread was directly relevant, and there was no solution there, and the thread was “closed automatically”. So, here I go again.
When using “Render elements” to render light and zdepth passes, my alpha opacity planes appear as solid planes. Big problem, causes sucky compositing.
I’m rendering a big city scene with lots of planes, so rendering every alpha plane seperately is not an option.
