I’m having trouble using the paint bucket to add texture to anything. This is happening when I use both the stock materials that are included, and the imported images as a material. I tried importing my image as a material, but it still didn’t work.
Either the scale of your model is so large that the ‘Textures’ are too small to see or you have set the View to just Shaded.
Check how big your model is.
Go View/Face styles/Shaded with Textures.
