brush shading

基本解释

Now we take a soft brush again, with the opacity set to about 15% and start the shading.
现在我们再次采用软的笔刷，并将透明度设置到15％开始表现暗部。
When you are finished with the shading, use a smudge tool to smooth the surfaces. I use a hard round brush with about 40% strength!
当你结束对暗部的绘制后，要用污迹之类的笔刷来平滑表面。我用的是硬的圆形的笔刷，强度为40％。
The other one I use for precise shading – basically I just select the desired shape and use plain Gradient and Brush Tools to dose the amount of shade.
使用形状工具，我创造了基本的，主要因素，试图从一开始就坚持与选择的配色方案。
