ah... wow. That's probably the only one parameters tab which I didn't check :) Thank you!

Thanks, @bezo, now I've got the idea. But could you, please, take a look what's wrong in my case? Because it still doesn't want to work. Among my clones I have only 2 types of fillets and nothing random in between. The scene is also attached. cloner-fillets.c4d

Hi, @Havealot, I checked the attached scene file, but could not find the place (in attributes) where you connect Plain Effector to the tubes inner radius. Because I would like to apply the same technique to the cylinders' fillet, instead of tube inner radius. Thank you in advance!
