Material Animations enables you to create animations of a material’s value based or color properties.
Adding a Material Animation
The Material animations can currently only be added through the Material Graph.
- Right click the material you want to animate either in the Real-time View or in the In-Project Library and select Edit Material Graph.
- Inside the Material Graph go to Nodes > Animation and select the type of animation you want to add.
This will add a folder (yellow node) in the timeline witch contains all animations of the material. The Material animation nodes are represented as red nodes in the timeline.
Material Animation Types
Provides a smooth transitions between two or more color values. You can apply a Color Fade to your material’s diffuse, specular, and opacity map. You may also apply a Color Fade to any material value like roughness, refraction index, power, contour width, etc.
Learn about the Color Fade Node.
The Curve Fade animation provides custom transitions between numerical values. You can apply a Curve Fade to your material’s diffuse, specular, and opacity map. You may also apply a Curve Fade to any material value like roughness, refraction index, power, contour width, etc.
Learn about the Curve Fade Node.
The material animation is tied to the material and thus will apply to all parts with the affected material. If you only want to affect the material of a specific part, you have to un-link it.
Unlike the other animation types the material animations will not be listed in the scene tree under any group or part. Rather, the material animation “lives” inside the Material Graph.
If you have parts with co-planar surfaces and transparent materials, Opacity maps or use Part Fade animations or Curve/Color Fade animations to manipulate the opacity, this may result in surface areas that are not rendered as expected where the 2 parts intersect.
The workaround is to make sure the parts are not positioned so the surfaces are co-planar, but in stead have a very slight gab between them.
