What is your workflow?
You have an idea for an add-on in Blender, but don’t want to do the Python scripting yourself. After contacting me, we discuss the idea by email or a video call. We put together a list of requirements that must be met by the add-on. After that, I explore the idea free-of-charge and see if my expertise fits your needs. If this is the case, I start working on the project on an hourly basis (55 USD per hour as of March 2022). We have regular feedback rounds to check whether we are still on the same page. I will send you interim products (Python files) in exchange for interim payments, and the final product if all requirements are implemented.

What kind of projects do you do?
To get an idea of what kind of projects I’ve been involved in, take a look at the Add-ons page, or go over to https://blendermarket.com/creators/3d-operators. During our first conversation, we will discuss if my expertise fits your needs.

What does a customized Blender add-on cost?
Hard to say, as it depends on the complexity of the add-on. Here’s some examples to give an idea:
– A very simple script that calculates the surface area of all objects in the scene, should cost 50-100 USD.
– A simple script that calculates the average vertex-to-vertex distance between two objects and automatically exports the average distance as a .txt file, should cost 100-200 USD.
– A graphical user interface (GUI) that allows the user to place anatomical landmarks on an object and calculate distances and angles between them, should cost 200-400 USD.
– Complex add-ons with multiple importing and exporting steps, mesh transformations and manipulations, and an elaborate GUI to allow much freedom for the user, can easily add up to 1000 USD or a multiple of that.

How should I transfer the costs?
Payments should be transferred via Paypal.

How is your software liability regulated?
3D Operators in no way liable for Blender crashes, loss of digital files, or physical damage.

Can I sell the add-on after I received the final product?
The add-ons are released under GNU GPL license, which means you can modify and (re)distribute the final product. And charge people a fee for it. In fact, anyone who obtains a copy of the add-on can do this.
