I’ve always had this problem rendering grass and other objects separetely and then compositing them together.
Take the below example. I rendered the cube (cycles) and grass separetly (In grass, I had the cube material set to “sky” so it creates an alpha of 0 wherever the cube is visible to the camera). Do you see the white line on the right edge of the cube? That’s the background showing through.
Yes, it might be because I am using two different renderers. I rendered the cube separately in BI and still the same thing happens. Although it is less pronounced in this case.
But when I render the entire lot together they are seamless. No gaps whatsoever. What is behind this entire thing? I’ve seen so many pictures made with blender that has loads of grass in it. How was the issue solved there? Is there a better way to render things separetly than mine?
I would like very much to hear all you guys methods or workarounds.
Thanks in advance for any response,
