38
Q

MATERIALS

leaving on the other side.

A

Transmission

39

Volume Shader

41
Q

MATERIALS

is a physically-based volume shader that can be used to create a wide range of volume materials.

A

Principled Volume

42
Q

MATERIALS

What are common terminology we can encounter in working Volume Shader?

A

43
Q

MATERIALS

This emit lights from the volume

A

Emission

44
Q

MATERIALS

This let lights scatter in other directions as it hits particles in the volume.

A

Volume Scatter

45
Q

MATERIALS

Absorb part of the light as it passes through the volume.

Use to shade smoke, halo glass, or a mixed to scatter node.

A

Volume Absorption

46
Q

MATERIALS

The altering the shape of surface and volume. Makes the mesh more detailed.

A

Displacement

47
Q

MATERIALS

3 Types of Displacement Methods

A
  • Bump Mapping
  • Displacement
  • Mixed
48
Q

MATERIALS

A virtual altering the shading but not the mesh.

Least accurate but memory efficient. Often used to add smaller details on a model.

A

Bump Mapping

49
Q

MATERIALS

Most accurate but memory intensive it requires a finely subdivided mesh.

Apply actual displacement to the
mesh

Baked Displacement Maps, is one of the best result to achieve with image.

A

Displacement

50
Q

MATERIALS

Use actual displacement for the bigger displacement and bump for the finer details.

Can provide a good balance to reduce memory usage.

Mixed

51
Q

MATERIALS

are the input needs to produce a materials, by default we have Principled BSDF.
