I'm on version 2016.49, but I've noticed this periodically with other releases. When changing the TYPE, the snowflakes look the same. It used to be that type 1 was a single node, Type 2 was a diamond shape, Type 3 (or 4) was an L shape. Now, all Types look the same as a single node.
I'm dropping the effect on a matrix which should be the best way to see different Types. I've tried changing the Render Style from Default to Per Preview which changes from a single node to some type of randomness, but not the way the flakes used to look.
This was user error. In the color picker I also had BLACK selected which is the color used for the "outside" pixels of the snowflake. Carry on, nothing to see here, lol.
