Change the color of the grid to create blocks

I want to change the color of the grid to black, I don’t understand where the texture is or where the color is determined for the grid, maybe someone tried to change the color of the grid for blocks?

Hi there! I am new to the software/community but would love to help you here.
Perhaps it can be located under ‘Padding Color’ in the third image? Try clicking on the arrow next to it and see if it opens up a window that may be able to adjust the color!

This color parameter did not affect anything, you need to create your own textures, I don’t know how to create a mesh texture, I tried to do the same in Photoshop, the engine also needs to create materials based on the mesh
