use as default?
Texture Paint Workspace

WORKSPACE
the default workspace is
used to create a more controlled
UVW Mapping by adding seam and rearranging it to lessen the overlapping UVs
UV Editing
WORKSPACE
What are the 2 views in UV Editing?
- UV Editor
- Edit Mode
Controls and define the appearance and substance of mesh such as its color, texture, reflection to Light
It is a data blocks that can be assigned to more than one 3D object and different materials on one 3D object.
Materials
MATERIALS
What are Materials 3 Shaders?
- Surface
- Volume
- Displacement
MATERIALS
This controls the textures and light interaction at the surface of the mesh.
Surface Shader
MATERIALS
It defines how light is reflected and refracted at a surface.
It can imitate glass, metal or just any opaque object.
Bidirectional Scattering
Distribution Function (BSDF)
MATERIALS
What are common terminology we can encounter in working Surface Shader?
Reflection, Transmission, Refraction
MATERIALS
BSDFs reflect an incoming ray on the same side of the
surface.
Reflection
MATERIALS
BSDFs transmit an incoming ray through the surface,
leaving on the other side.
Transmission
MATERIALS
BSDFs are a type of Transmission, transmitting an incoming ray and changing its direction as it exit on the other side of the surface.
On the Principled BSDF, Refraction can be adjust thru IOR by default its 1.45
Refraction
MATERIALS
This defines the interior of the mesh.
This is utilize to create fire and smokes or combined with surface to create a halo texture.
Volume Shader
MATERIALS
is a physically-based volume shader that can be used to create a wide range of volume materials.
Principled Volume
MATERIALS
What are common terminology we can encounter in working Volume Shader?
Volume Absorption, Volume Scatter, Emission
MATERIALS
This emit lights from the volume
Emission
MATERIALS
This let lights scatter in other directions as it hits particles in the volume.
Volume Scatter
MATERIALS
Absorb part of the light as it passes through the volume.
Use to shade smoke, halo glass, or a mixed to scatter node.
Volume Absorption
MATERIALS
The altering the shape of surface and volume. Makes the mesh more detailed.
Displacement
MATERIALS
3 Types of Displacement Methods
- Bump Mapping
- Displacement
- Mixed
MATERIALS
A virtual altering the shading but not the mesh.
Least accurate but memory efficient. Often used to add smaller details on a model.
Bump Mapping
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.
Displacement
MATERIALS
Use actual displacement for the bigger displacement and bump for the finer details.
Can provide a good balance to reduce memory usage.
Mixed
MATERIALS
are the input needs to produce a materials, by default we have Principled BSDF.
Shader Nodes
