batoms installation issue inside Blender

[Punit Kumar]

Hello Beautiful Atoms users!

I'm new to the Beautiful Atoms package and tried to install it in Blender. Unfortunately, I'm facing an installation issue when I'm trying to move the batoms folder to the addons directory, as suggested on the Beautyful Atoms webpage. After successfully moving the batoms folder to the addons directory, when I'm trying to enable the batoms add-ons under preferences, it doesn't show those add-ons. 

Does anyone face similar issue? If yes, please suggest a possible solution to resolve this issue. Any suggestion is highly appreciated.

Best regards,

Punit

Hi Punit,

Which system do you use? Windows, Linux ?

Did you try to enable the add-on by hand on GUI, or using the Python script?

Hello Xing,

I fixed the installation problem I encountered when installing Beautiful Atoms in Blender. After a successful installation, I encountered an index error when I ran my installation test. The full traceback of the error is

Traceback (most recent call last):
  File "<blender_console>", line 1, in <module>
  File "C:\Program Files\Blender Foundation\Blender 4.1\4.1\scripts\addons\batoms\batoms.py", line 156, in __init__

                                                ~~~~~~~~~~~~~~~~~~~^^^
IndexError: bpy_prop_collection[index]: index 3 out of range, size 3

To run the test, I used the Python code given on the webpage (https://beautiful-atoms.readthedocs.io/en/latest/getting_started/installing/windows.html#test-your-installation).

Can you or anyone in the community help me to solve this error? Any help is highly appreciated.

Best regards,

Punit

Hello Xing,

Thanks for your reply. I'm using a windows machine. I didn't try it with python script but yes I tried it by hand on Blender GUI. Unfortunately in GUI when I tried to enable the batoms it doesn't show that add-on although I move it to the addons directory. I also follow the instructions in one of your YouTube videos where you show the manual installation of beautiful atoms in blender.

Best regards 

Punit
