Hello sir, Can you tell me how to do vertex color and cutting hole using boolean modifier in blender 3.5 please?
Hi @Zulfariz ,
Can you tell us what point (time) in the course you are referring to please?
Also, I don't think there is much difference between 3.2 and 3.5, where Vertex Colors and Booleans are concerned....
JL does some boolean magic to make the face of PotHead in this lesson:

And Kent uses Vertex colors extensively in Cubicity. You'll see as you go along.
sometimes the boolean tool does not work in "difference" if your normals are flipped. You can check that here 
both should be blue!
Good luck forward
