According to google, laziness is the source of innovation. Some examples of inventions made by lazy people include:

• Microwaves: Invented in 1967 by Amana after an engineer was too lazy to wait for his popcorn to pop
• Escalators: Invented in 1892 by Jesse Reno because he didn’t want to climb stairs
• La-Z-Boy recliners: Invented in 1928 by two cousins who thought sitting up was too much work

Mallet: Modular Asset Manager

basically laziness moves the world, this is more true for the 3d industry than any other industry, imagine a scene where you have to kitbash different assets , you could do this the manually, adding pieces together one by one but that will drive most of us crazy, or you can use mallet modular asset manager, this addon can be used with any asset kit, to assemble assets into different object, a great example is a kit of pipe joints that can be put together to make pipe connections. the addon will handle everything for you, from rotating, scale move, and switch between different assets, you just tell it what part fits where once and then the rest is automatic, turning something stressful to something easy and satisfying.

Attachify Pro

Creating an animation of an object attached onto the ceiling or something else seems quite easy until you try it, ropes are easy to create with a cloth simulation system but the cloth simulation system does not work with the rigid body so you can’t attach the rope to the object, thats why its quite impressive that this attachify addon handles both the rigid body system and rope physics at once, even simplifying the connecting process, and moreover everything works in realtime.

Node Fx 1.0 (Node Effect) Procedural Shaders

being lazy is the only way you are going to complete project, infarct its not a bug its a feature, this is how you are expected to work in the industry, no one expects you to do everything on your own, you are expected to take advantage of other peoples libraries like this library of over 35 meticulously designed animated procedural shaders, from moss effects, crystallization, rusting effects and more, since this is a new library you can get it at a 25% discount

Cell Fluids

sofar cell fluids is the only realtime fluid solver for blender, everything else you have to bake your results to see them, while the simulation is more of a 2.5D effect instead of true 3d, the quality you get is enough for most renders

Flip Fluids

if you want more detail and a more realistic solver for complicated fluid simulation, flip fluids provides everything that mantaflow is missing, from white water effects with awesome large scale fluid simulation, high viscosity effects, surface tension and more

Physical Open Waters

still on the topic of fluids, water is a complicated thing that each scenario requires a different approach, if you want to render large realistic oceans, that have realistic ocean behavior with foam and interaction with other object, the physical open waters addon is going to be the best addon for this scenario.

Light Wrangler: Cursor-Targeted Lighting Add-On For Blender®

if there is a tool you should get, get something to help you with lighting, the only way to get better at lighting is being able to play with your light setup in an easy and quick way, like what the light wrangler addon provides, if you think a surface of an object should be lit, you just point at it, then a light will be added for you at that target that area, and you can do all the adjustments you need right in the view port, you can move the light by just moving the target on the surface of the object, this is also possible for reflections and shadows with light wrangler.

Bp Geogen Ultimate Generators Bundle

i got vines, rocks, scales, cables, ships, you name it, planets, fire, grass, trees, snow more than 50 generators in one bundle

Population – Crowd Simulation

what else do you want, animated crowds, a diverse collection, with a large animation library, in different categories like casual, business, sports, like what exactly do you need people walking, running, in the gym, dancing, gossiping, you name, i got you covered this is population a blender crowd simulation addon that is a one size fits all, for background or foreground characters

Physics Placer V1.1

do you scatter objects in blender, do sometimes your scattered objects look weirdly placed, like they should fall but are not falling, maybe they are intersecting with each other, or they simply dont look realistically placed, well its because you are not using physics to scatter your objects, this physics placer addon just does it better with physics, weight, gravity and collisions all considered.

Geo-Swarm

if physics placer is for scattering objects, geo swarm is for spawning live animals like insects birds, bugs and more, it comes with a swarm feature that includes attraction to attract things to a target, avoidance to scare off things, gravity, follow curve, endless spawn, jumping, barrier and more, geo swarm also comes with a dedicated library of insects that are ready to use all in realtime.

Procedural Traffic – Addon And Rigged Cars

there is no reason why your cities should be empty, before addons it was understandable because making cars was hard, animating cars was hard and simulating realistic traffic was impossible too, but with new addons like procedural traffic, you get everything in a single package, you get hundreds of cars, fully rigged and animated, and the addon also handles the traffic simulation its self, all you have to do is setup the roads and the addon will do the rest.
