To add parameters to the collection, click the Add Element (+) icon in either the Scalar or Vector Parameter section. Double-click the asset to edit the MaterialParameterCollection.Ī new window opens displaying the Scalar and Vector Parameters contained within the MaterialParameterCollection. This example uses the name MPC_GlobalParams. Rename the MaterialParameterCollection asset to describe the types of parameters it will contain. Select MaterialParameterCollection in the context menu. Right-click in the Content Browser, and expand the Material subcategory in the Create Advanced Asset section. Use the following steps to create a MaterialParameterCollection and add a parameter. ![]() MaterialParameterCollections are a discrete asset type created in the Content Browser. The coloration of effect across the time of day and overall diffuse lighting color for the water are also being controlled.Ĭreating and Editing Material Parameter Collections ![]() The sun angle and color is also tracked and used to correctly colorize the water crests and limit the effect to only times when light shines directly through the wave crests (when the player is looking toward the sun). That position information is used to move the flowers and grass away from the player as they walk nearby. The player's position is tracked and fed into the foliage. The flower morph states along with the speed and strength of the wind. In the example above, global parameters stored in a Material Parameter Collection are used to control the following aspects of the scene. You can also use Material Parameter Collections to drive per-level effects, such as snow amount, destruction amount, wetness, and so on, which would otherwise require settig individual parameter values within many different Material Instances in your Level. It is a powerful tool that artists can use to pass global data into multiple Materials at once. A MaterialParameterCollection is an asset that stores an arbitrary set of scalar and vector parameters which you can reference in an Material.
