In this lesson video, we are going to add global shading to our illustration. Global shading is just my own term for large sized shadows and also cast shadows or shadows that are being emitted by certain objects that fall unto other objects or areas. Okay? for global shadings, you can create them in the same layer with the local shading. But I found that separating the two gives you more flexibility later to tweak them further. For example, you can colorize the local shading and the global shading later with different colors etc.
So let's create a new layer on top of the local shading layer. And let's rename it to S for shading. Just like the local shading layer. It should has the inherit alpha turned on and also use multiply blending mode. We need to add a shading layer also under work and clear Group layer. Okay, let's start creating large soft shadows on the tray Tron.
Make sure the shading layer is selected. Select the airbrush preset for this. Now just imagine that there will be shadows from the leaves so the upper areas of the trunk should be darker. And for the middle area, again, you need to remember that the light is coming from the top right direction, so we need to add shadows on the left bottom area of the tree. For the cliff, the grasses and the leaves the process is fairly similar. So I'll just speed up the video for now.
Just remember to use the correct layer for this process. After we have the global shading Next, we want to add custom shaders to our illustration. Now forecasted shadows, you can create these in a separate layer, or you can directly pane on the shading layer. For now, let's just use the existing shading layer for the cast of shadows. And let's start with the tree trunk force. Press z, and try to create leaves shape on the tree Tron.
Just imagine that the sunlight hit the tree trunk, but some of the lights got blocked by the leaves. Essentially, we need to create a leaf silhouette for the shadow until the center area where the direct sunlight cannot touch the trunk anymore. Use the airbrush again and make the brush size bigger and just brush like this. Okay, now let's zoom in a bit and use our smear brush to smooth out these sharp shadows. Okay guys, for the rest of the process it is basically the same, you create a selection of where the light should travel, and then use the airbrush preset to add colors. And finally, use either the smear brush or the blur brush to tweak the shadows further
