I have several questions, along with screenshots.
- What do I need to do to make the shader editor look like this?
- Can I customize the Object Color with any colors I want?
- How can I fix this?
1- From a Google search, this seems to be possible only with a paid addon.

2- Instead of using “random” color, switch to “material” and set the viewport color of your choice in the material settings. Not only you can choose the color, but also viewport roughness and metallic for each material.

3- There must be a modeling mistake in there. Try selecting everything and do a “merge by distance”. If there are disconnected edges or overlapping geometry, this will fix it. It could also be because of a face hidden inside the model, in which case you need to delete it. It could also be a problem with normals direction, so try selecting everything and recalculate the normals (shift+n).
You’ve already received help, but for the future : Please post a thread for each individual question, and name them accordingly. The post title should reflect your issue as succintly as possible, and will serve as reference to anyone who is having a similar issue and looks it up on the forum search. Thank you
Thank you very much. You helped me a lot.
So, it’s also an experimental feature in version 5.0.
Thank you.
I understand
It has been an experimental feature for quite some time.
It is not as good as the addon, in your screen shot the preview of the mapping node is showing the UV cords which is what you would expect as it is the output they are using.
The Blender experimental version only shows generated cords no matter which output you use.
To see the UV’s I have to put in a math node (that does nothing - add 0).
This happens with many nodes in the experimental version, it only shows one of the outputs without taking into account the output you are using.
For example
The voronoi should be showing the distance output (the one I am using) not the colour output.
To see the Distance output again you have to use an extra node that only has one output
So the addon does a much better job than the experimental feature (which was never finished)
It works! Thank you very much.
thanks for the information
