Super cool new feature - childed spawners! In the next release you will be able to child spawners to a parent... this will enable you tor create sophisticated spawner chains... which can be activated with a single control click! In this example - first the tree spawner runs, then each of the grass spawners run. The grass spawners were set up with opposing perlin masking to get the nice mutually exclusive grass and fern patches. I then manually added the flowers with another click. Could have done them all in one as well This nesting can go as many levels deep as you like. This enables an incredible amount of flexibility! Another quick spawn - this time added some rocks.
