MakeLayerTable

Create or refill the layer table: a 256 x 1 RGBA32F texture, one texel per paint layer id, that the terrain material reads with Load (layer ids are 8-bit, so a table replaces four-layers-per-vector parameters).

Description

The texel layout is the material's: x the layer's tile size (m), y its displacement amplitude (cm), z its height-map mean (0..1), w 1 where the layer projects onto steep sides. Uncompressed, nearest, no mips, never streamed, so a value reads back exactly. The asset is not saved.

Parameters

Name	Type	Default	Meaning
`PackageName`	`const FString&`	—	Long package name of the texture.
`Rows`	`const TArray<FLinearColor>&`	—	Row i is layer i; missing rows are zero, rows past 256 are an error.

Returns

The texture, or null when Rows holds more than 256 entries.
