−	* [[Cloud Layer v2 - Optimisation Tab]]

		+	* '''Use 2D shadow map:''' Shadow maps were originally designed to avoid long render times when extreme anti-aliasing values would not resolve noise issues in the shadows cast by a cloud layer. When enabled, this setting generates a 2D map for the cloud layer at the start of the render process. You can think of the shadow map as a 2D image of the cloud layer’s density values from the top view. Internally, Terragen positions the shadow map at approximately the center of the cloud layer on the “Y” axis and as rays are traced through the cloud layer the density values are used to modify the lighting. Shadow maps can be used to cast shadows onto the terrain, objects and other cloud layers, but not the cloud layer itself.
		+
		+
		+	*'''Shadow map resolution:''' These values determine the width and height of the shadow map created for the cloud layer. Higher values take longer to calculate but result in more detail, while lower values tend to be softer and have less contrast, due to less detail. The cloud layer’s radius plays an important role in determining the level of detail of the shadow map. For example, a cloud layer with a radius value of 50,000 metres and mapped into 200 pixel by 200 pixel shadow map will appear softer than a cloud layer with a radius value of 20,000 metres mapped into the same resolution.

		+
		+
		+	*'''Shadow map blur radius:''' When a cloud layer is animated its shape can potentially change every frame which could introduce unwanted flickering into the shadows cast by it. The "Shadow map blur radius" was designed to reduce the flickering by blurring the shadow map for the cloud layer. These values determine the blur radius in pixels to apply to the shadow map after it has been internally rendered, therefore the "Shadow map resolution" values are important to take into consideration. For example, a "Shadow map blur radius" of 2 will have a greater softening effect on a "Shadow map resolution" of 100 pixels by 100 pixels compared to a Shadow map resolution of 1000 pixels by 1000 pixels. The higher the "Shadow map blur radius" value the softer, or more blurred, the shadow map will be.

		+	*'''Use voxel buffer:''' When enabled, a voxel buffer is created based on the "Millions of voxels" value.
		+
		+
		+	*'''Millions of voxels:''' Sets the maximum number of sample points, or voxels, that will be generated to form the voxel buffer. Higher values create more sample points, which results in having more detail in which to calculate shadow and lighting solutions. This can have a large effect on both render times and RAM use.

		+
		+	*'''Voxel buffer resolution:''' This read-only display shows the automatic distribution of the "Millions of voxels" in a grid-like pattern across the three axes of the voxel buffer.
		+
		+
		+	*'''Accelerate empty space:''' When enabled, empty voxels in the voxel buffer are first identified in order that they may be skipped and not calculated during the render. This can result in render speed improvements on certain types of clouds such as those used globally.
		+
		+
		+	*'''Visualise voxels:''' When enabled, the voxel buffer for the cloud layer is displayed in the 3D Preview and used for rendering the Cloud Layer v2.

		+	</ul>
		+
		+
		+	*'''Use voxels for shadows:''' When enabled, the voxel buffer for the cloud layer will be used for cast shadows. This can result in faster render times and avoid noisy shadows, but may produce shadows with less detail.
		+
		+
		+	*'''Transition dist. (voxels):''' This setting, measured in voxels, is the transition point at which shadows are calculated using the cloud layer’s actual volume instead of voxels. This leads to more accurately cast shadows when the shadow rays are shorter, such as bouncing around inside the cloud or when close to the terrain.

-* '''Sun glow amount:'''  When the sun is behind the cloud layer and opposite the observer (camera), increasing the "Sun glow amount" will scatter more light within the cloud, brightening the highlights of the cloud, especially in the area of the silver lining effect.

		+	The bright outline along the edge of the cloud known as the silver lining occurs when light is scattered by cloud droplets along the cloud's outer edge. This contrast between the change in brightness with respect to the angle of the sun, is most clearly seen when the Cloud Layer v2 clouds are back-lit by the sun. When the "Sun glow amount" and "Sun glow power" settings are set to 0, light is scattered uniformly in all directions decreasing the silver lining phenomenon.

		+	* '''Altitude offset function: '''The shader or function nodes assigned to this setting apply an offset to the clouds within the cloud layer, up to the extent of the cloud layer’s depth. In other words, you can’t offset clouds beyond the boundary of the cloud layer itself. The offset value is in metres, so if the output range of the assigned shader or function nodes is 0 to 1, you can multiply the output via the “Function multiplier”. Each cloud layer has a profile which is determined by the settings located on the Tweaks tab, such as “Taper top and base”. When the clouds do not fill the cloud layer completely, due to the cloud profile or low “Cloud coverage” then the “Altitude offset function” can shift the clouds up and down, limited to the extent of the cloud layer’s depth.
