base classes — `bpy_struct`, `Modifier`

class `bpy.types.``VertexWeightMixModifier`(Modifier)

    Default weight a vertex will have if it is not in the first A vgroup

    Type: | float in [0, 1], default 0.0

  `default_weight_b`

    Default weight a vertex will have if it is not in the second B vgroup

    Type: | float in [0, 1], default 0.0

  `mask_constant`

    Global influence of current modifications on vgroup

    Type: | float in [-inf, inf], default 0.0

  `mask_tex_map_object`

    Which object to take texture coordinates from

    Type: | `Object`

  `mask_tex_mapping`

    Which texture coordinates to use for mapping

    - `LOCAL` Local, Use local generated coordinates.
    - `GLOBAL` Global, Use global coordinates.
    - `OBJECT` Object, Use local generated coordinates of another object.
    - `UV` UV, Use coordinates from an UV layer.

    Type: | enum in [‘LOCAL’, ‘GLOBAL’, ‘OBJECT’, ‘UV’], default ‘LOCAL’

  `mask_tex_use_channel`

    Which texture channel to use for masking

    Type: | enum in [‘INT’, ‘RED’, ‘GREEN’, ‘BLUE’, ‘HUE’, ‘SAT’, ‘VAL’, ‘ALPHA’], default ‘INT’

  `mask_tex_uv_layer`

    UV map name

    Type: | string, default “”, (never None)

  `mask_texture`

    Masking texture

    Type: | `Texture`

  `mask_vertex_group`

    Masking vertex group name

    Type: | string, default “”, (never None)

  `mix_mode`

    How weights from vgroup B affect weights of vgroup A

    - `SET` Replace, Replace VGroup A’s weights by VGroup B’s ones.
    - `ADD` Add, Add VGroup B’s weights to VGroup A’s ones.
    - `SUB` Subtract, Subtract VGroup B’s weights from VGroup A’s ones.
    - `MUL` Multiply, Multiply VGroup A’s weights by VGroup B’s ones.
    - `DIV` Divide, Divide VGroup A’s weights by VGroup B’s ones.
    - `DIF` Difference, Difference between VGroup A’s and VGroup B’s weights.
    - `AVG` Average, Average value of VGroup A’s and VGroup B’s weights.

    Type: | enum in [‘SET’, ‘ADD’, ‘SUB’, ‘MUL’, ‘DIV’, ‘DIF’, ‘AVG’], default ‘SET’

  `mix_set`

    Which vertices should be affected

    - `ALL` All, Affect all vertices (might add some to VGroup A).
    - `A` VGroup A, Affect vertices in VGroup A.
    - `B` VGroup B, Affect vertices in VGroup B (might add some to VGroup A).
    - `OR` VGroup A or B, Affect vertices in at least one of both VGroups (might add some to VGroup A).
    - `AND` VGroup A and B, Affect vertices in both groups.

    Type: | enum in [‘ALL’, ‘A’, ‘B’, ‘OR’, ‘AND’], default ‘ALL’

  `vertex_group_a`

    First vertex group name

    Type: | string, default “”, (never None)

  `vertex_group_b`

    Second vertex group name

    Type: | string, default “”, (never None)
