Video: Painting in 3D

Blender offers texture painting, which is painting in three dimensions. It's as close to painting a real object as you will ever get on the computer I think. It's a special mode within Blender and in the 3D view here, we switch to Texture Paint. When you do that, a couple of things happen over here. One is a Paint panel comes up which allows you to draw, soften or smear a color with brush controls and brush patterns and textures and allows you to have a Mix Brush where you mix your colors in with the existing colors or to Multiply, Darken, Erase and then Add Alpha too.

Painting in 3D

Blender offers texture painting, which is painting in three dimensions. It's as close to painting a real object as you will ever get on the computer I think. It's a special mode within Blender and in the 3D view here, we switch to Texture Paint. When you do that, a couple of things happen over here. One is a Paint panel comes up which allows you to draw, soften or smear a color with brush controls and brush patterns and textures and allows you to have a Mix Brush where you mix your colors in with the existing colors or to Multiply, Darken, Erase and then Add Alpha too.

So, you can actually paint holes into the surface that you are painting and you know to paint, your cursor changes to a paintbrush and you just start painting. Now, what's happening over here in this window is that each of these petals, each of these five petals of the flower, are all mapped to the same material. So they all have the same texture and the only texture that's active is this BlendInside. And all I have done is I have made some minor modifications to the flowers that are in the BBB DVD. This isn't my work.

This is the work of the Big Buck Bunny crowd. This texture is mapped to UV, through the UV Texture coordinates and it's mapped color and it's mixing that color in 100%. So it's actually going to override any base color of the petal. So since each petal is mapped to the same texture, any changes I made to one is instantly reflected in the other four. And the other thing that's going on is over here in two dimensions based on the UV texture and I'm just going to go ahead and switch into Edit Mode right now and select a petal and then Ctrl+L to select all of the faces of that mesh.

You can see that this petal maps with the UV coordinates to this area of the image and this image is actually an image file that's saved over here and is called flower.tga and I'm saving in the Targa format which supports the Alpha channel. So, when we are over here in Texture Paint Mode, I'm going to switch back here to show you the panel. As I'm painting, I'm just painting in three dimensions here with my little brush. I have got the white color. It's a very small brush. The other neat thing I can do is change my brush color.

I can also sample on a picture of an actual flower if I had an actual flower picture over here I could actually sample. Maybe I'll change my brush size a little bit, make it a little less opaque, increase the Falloff. These Ps here is if you are using a Wacom tablet and you want to use pen pressure sensitivity, you can enable that and then as you are painting with your tablet in 3D, then the strength and this control is affected by how hard you are pressing on the pen.

I can change into Airbrush Mode, which means it continues to spray as long as I hold the mouse down. I'm just trying to make a little pretty design. Then the other thing that's kind of cool is you can come over here and at any time, you can save your updates just by doing an Image > Save and then that will save it back out. I recommend that you save your images to your library file, under image textures and we'll probably call it new flower petal. But now over here, if I press N, I can see that I can actually paint a movie as well or if I come over here and I enable my image painting, now I can switch into my image controls and look at my Paint tool and say paint in red.

Now if I paint the image over here, look what's happening over here. So I'm making a really pretty little variegated. So, I can paint in 2D just like I can in Photoshop or whatever. Paint a 2D image over here and have Blender automatically map this image through these UV coordinates and the UV coordinates I should mention are right here under the Mesh panel, under UV Texture, this is the one that's active. So it's mapping this image here to the three-dimensional object over here and that's texture painting in Blender.
