Unreal Engine - Material and Particle System

Which node makes a texture move an over time?

• Texture Coordinate

• Constant3Vector

• Panner

• Lerp

The 'Roughness' input in a material graph affects:

• How shiny or matte the surface looks

• Transparency of the material

• The texture resolution

• Particle spawn rate

'Color Over Life' in a particle system is used to:

• Control particle spawn rate

• Change particle velocity

• Change color of particles during their lifespan

• Add shadows to particles

Which node allows you to define the surface's texture appearance?

• Multiply

• Texture Sample

• Panner

• Scalar Parameter

Which particle module controls how many particles appear per second?

• Spawn

• Lifetime

• Color Over Life

• Velocity

To create animated fire textures in a material, which nodes are commonly used?

• Fresnel + Lerp

• Multiply + Scalar

• Panner + Texture Sample

• Constant3Vector + Mask

The ‘Emissive Color’ input of a material affects:

• Reflection intensity

• Self-illumination (glow)

• Transparency

• Surface normal direction

The 'Lighting Needs to be Rebuilt' warning shows when static lighting changes are not updated.

A Panner node only works with Normal Maps.

In a Particle System, the 'Initial Size' module defines how big particles start.
