Thank you Jim,
I used two primitives of the same type, both Cubes, one without fillet and the other one with fillet to give it that spherical look. I wasn’t aware that for two primitives to Blend under a cloner they had to have enough segments in between. I was looking at Zachary Corzine’s presentation and he was able to drop two cubes under a cloner, just as I did, and had them Blend, without any other tool. His result was similar to yours with the Spherify deformer, but he didn’t use any deformer.
