Materials applied to the lava in the elemental demo are not rendering during the cinematic.
With the dim lighting in the cinematic the lava appears very dark.
The following shader compile warnings are found in the output log
LogShaderCompilers:Warning: Failed to compile Material /Game/Elemental/Environment/Lava_Assets/Materials/M_LavaFlow_01.M_LavaFlow_01 for platform PCD3D_SM5, Default Material will be used in game.

Expected Result: All materials render completely
Actual Result: In parts of the cinematic lava is displayed with the default material
