Blender Python Tutorial : How to create and assign a Material Shader [learn python for beginners]

In this Blender Python Tutorial, we will be taking a look at not only creating a Shader Material but also assigning that material to the currently selected object.

Looking to learn Python for beginners? You are in the right place. Be sure to check out the Scripting Playlist!.

We can create something simple or something complex but both ways will be using an Operator. We first create a panel where our button will live. Then we can create a simple operator, that when pressed will create and assign a Shader Material to the Selected Object.

If you want the user to have any options, we can easily upgrade the simple operator and make it become a popup dialog box. We can then giver the user control over any setting or option. In this example we want the user to be able to set the color before adding the Shader.

I hope you found this Blender Python Tutorial helpful and as always thanks for watching!

Thanks for these. There's a lack of good walkthroughs regarding this stuff so this is great! Definitely going to work my way through your playlist.

Thank you for this - though I didn't use it as is, I was able to manage recreating my favorite shader tree arrangement from a single button press in my personal work add-on, and that felt epic! I like the way you walk us through each step and show how to arrive at a decision instead of just saying 'press this and type that'.

Thank you very much for the videos! They are very helpful for me. Thank you for going step-by-step and providing links to other videos too :)

These tutorials are truly the best for python in Blender that I have found on YouTube. The most helpful by far!

Would you happen to know how to append a material that is already created in a seperate blend file? I assume I need to find the file path to the blend file, but I'm not sure how to find the correct path to the blend file relative to the python script in code. Any help would be much appreciated!

Thank you very much for explaining materials.
I have a question, Could you please explain how to asign an image to image texture inside materials?

Hello everyone, working with blender/python on a window 10 box quad core 3.1 GHz with 8 GB ram everything is updated, still not used to navigating through blender reshape a windows unable to delete becomes a real mess, just have to shutdown to recover. 😓 The python code you provide is helping, still very much a newbie with blender kinda with python. I want to build a small town with in blender no trees or people, cars, lights, rivers, (sidewalks, at least for now) would really like to interact with in VR. Be safe everyone.

God knows UI/UX community need something of that sort integrated in Figma

How do you remove a material from an object by name? So if you have 5 materials (Blue, Red, Green, Orange, Purple) and wanted to remove the "Orange" and the "Green" material using a script?

Hello, I am working on a 3d project in blender and it's almost done. Now, I want to create some texture combinations (Noding textures) and get render. For example, there are 3 objects and some textures for each object, there are some combinations like that and the combination number is 2300 which is impossible to create it one by one. (By the way render will be animation render) How can I do it rapidly and short way. Can you please help me? Thanks.

When you added "col = bpy.props.FloatVectorProperty etc...." the script stopped working for me in Blender 2.93. Do you know why?

thanks for your vid! can you PLEASE - post how to - using blender python, switch materials for an existing object - not change the colors, not create new materials just change my cube from material red to material blue, both materials already exist- I am to stupid to figure it out. When I do it by hand the "info window" does not give me the command .Thanks much!

Hi, The material has some nodes and one of them is the RGB-node.
I already have the popup to change the color and it also changes it when i choose a color, but if i try to change it back to another color, this does not work. It only does it when i add a new object. It seems that it only let me set the color 1 time for each object. How can i change this?

Trying to make a shader for just a flat plane, nothing fancy or intricate. I just need to take camera output and use as a texture on plane. I can't seem to find any info on camera nodes. Just lookinf for info on the output and drag hook to material input for plane object. Any help to find camera nodes for this would be extremely helpful. Thanks.

Hi, can you make the addon to append the blend file using Pythone?

[andinic]

I am trying this on 3.1 and it is not working please help

Ok, so I have a rig with a python UI. And in the rig, there's a material with an Image Texture node. And I want to add a way to easily change the texture without having to go all the way to the Materials tab by implementing it to the Rig UI. But I don't know how to do so.
