Good work! I haven’t tried patterns yet, but I’ve used scatter on two projects recently. And I was really impressed. Despite running everything on my old Macbook Pro, I had no problems creating entire forests, fields of wild grass and a few hundred crows - all in the same scene. Viewport slowdown was minimal and render times remained almost the same. Deeply impressive.
If patterns are built on the same technology, I will be a very happy man.
(Sorry if this comes across as Corona marketing. Not my intention. But I’ve been truly blown away by the scatter performance).
