I have a while to go on the basics before I check these out but what is a good number to aim for when installing addons? I heard they have their own hotkeys that can intercepts blender and slow things down if too many are installed. I have a higher end pc with a amd ryzen 9 processor and a Nvidia geforce rtx 2060 graphics card. I am wondering mainly how many addons would be too many assuming I would like to get a few of the bigger addons like true terrain and asset packs and smaller ones like drag and drop addon. Any other tips on addons not mentioned would be great as well!
People mostly have lots of addons installed and you see their UI and it's completely changed. I wouldn't be surprised if they have 20 addons running at the same time. Sometimes they can glitch out and give you headaches and you don't know what's wrong, so be mindful of that. But it's ok, you don't have to think about it in what's a specific number, just test it out, you wont have to use everything at the same time, no need to have them all deployed. I think about addons as a swiss army knife where you take in and take out whatever you need at the moment. I turn them off and on for whatever situation arises.
It seems to me that there is no universal meaning. After watching some YouTube videos, I started installing everything that was advised in the hope that it would help me. In the end, I realized that I had done many unnecessary things and started all over again. I have only a few addons now and plan to add more as I go along. The comparison to Omar's swiss knife is very apt.
I have no paid add-ons, there are plenty of free add-ons that ship with Blender they just need to be enabled.
They may not have all the bells and whistles of a paid add-on, but they do the job for me.
Here are a few of the included with Blender add-ons I use.
Add Mesh: Extra Objects
Add Curve: Extra Objects
Mesh: F2
Mesh: Edit Mesh Tools
Mesh: Loop Tools
Node: Node Wrangler
