Trunk Generation Material Setup

C++ Source:

Editor Properties: (see get_editor_property/set_editor_property)

derive_from_trunk_texture_setup (bool): [Read-Write] When enabled, the Material and X Range for this generation are sourced automatically from the connected Trunk Texture Setup pin, matched by generation index.
material (MaterialInterface): [Read-Write] Material to apply to this generation.
u_range (FloatRange): [Read-Write] Limits horizontal coverage range.

Sets the portion of the mesh affected along the X axis, useful for restricting materials (e.g., moss/lichen) to a subsection.
x_offset (float): [Read-Write] Shifts texture position along X.

Moves the material horizontally across the mesh to fine-tune alignment or hide seams.
x_offset_random (float): [Read-Write] Randomizes X offset per instance.

Adds per-instance variation to the horizontal texture offset to break pattern repetition.
y_offset (float): [Read-Write] Shifts texture position along Y.

Moves the material vertically without changing scale. Useful for aligning repeats or hiding seams.
y_offset_random (float): [Read-Write] Randomizes Y offset per instance.

Adds per-instance variation to the vertical texture offset to avoid visible repetitions across branches.
y_scale (float): [Read-Write] Texture tiling scale along Y.

Adjusts vertical texture scale. Higher values increase tiling frequency (finer detail); lower values broaden patterns.
y_texture_mode (YTextureMode): [Read-Write] How textures align vertically (Default uses native tiling; Fit0_1 stretches once).
