Выглядит круто. И тематика у книги норм)

I fixed it!!!!!! Thank you so much. The problem was py36! I muse use py35! when I was using "animation_nodes_v2_1_windows_py35.zip" every anmation node was good. https://github.com/JacquesLucke/animation_nodes/releases Working page trun. Thank you so much brothermechanic. Awesome.

Oh I see. I will check your youtube. I installed animation node already. but some nodes was brockend. I don't know why. I sent you a message it attached my images. image 01 is using v.4.80 and image 02 is using v.4.79. when I was using v.4.80 there is line but every object name was gone. when I was using v.4.79 there is no line but there was object name. please check that. Thanks.

You must be a user of animation nodes!) I created my scene in the summer of 2018 at that time there were 2 versions of the blender, for python 3.5 and for python 3.7 I just ran a test and recorded video from the screen, so that it was clear in short - you need to install a blender-2.79b and animation nodes for python 3.5 https://youtu.be/02r0fVbVANI i think scene may be simple updated for blender-2.8*, as you can see -object input nodes no active in blender-2.8 and this is my tutorial for this scene https://youtu.be/XAZTGnW83pw Hope you get it worked!

Hello Thank you for purchase my model This scene created on Blender-2.79. Do you have this version? For animation you need install animation nodes addon for Blender-2.79 (it also worked on Blender-2.8X, but i don't test it a lot) So use blender-2.79 + animation nodes addon
