This week I focused on building volume cloud scene.
I used Houdini to make the cloud and the landscape. The main idea of it is using metaball to form the basic shape of cloud. After that I convert it into mesh, and then turn it into volume. By using several layers of volume noise, more details are added on these volume and make them looks like real cloud.
After that I did a simple landscape by using Houdini heightfield. I also exported several masks for the landscape and used them to make landscape texture.
Then I started to do the layout. By using the mask paint, scatter point and copy nodes, the landscape and clouds are arranged. I can also adjust the layout by changing the painted mask, which is quite handy.
