After many years on C4D, I started to learn Blender and follow the beginner tutorial series of Andrew Price.
On part 7 about particles, he changes the size and the random size of the particles group that needed to create sprinkles on a donut. He uses this menu, as shown in the doc blender doc
But for me, in Blender 2.79a the size / random size is available in the "render" tab while Advanced is unchecked. When Advanced is checked it disappears from the render tab and I can't find it anymore.
So if I want to tweak and randomize my particles, I have to check/uncheck.
Is it normal or am I missing a thing on 2.79 ?
edit : confirmed that in Advanced those settings are available in Blender 2.79.
