We are trying to figure out why our instanced geometry (cards with grass textures/opacity maps) are not rendering correct shadows. We did a test with a single card instanced to a null and the shadow is correct. However, the same card instanced 1 million times gives us solid shadows. Any idea why?

Here are some images to show the issue:

Hi,

The problem is that you need to enable the "Alpha shadows" option in the kernel node.

Thanks,
