Blueprint: Check Rvt Readiness, in Orrery › Terrain › Materials

Description

Two things are checked, on the parent material's own graph: it has an RVT Output node (a node held by a material function compiles nothing, though the cached flag bHasRuntimeVirtualTextureOutput says otherwise), and Tangent Space Normal is off (the RVT stores world-space normals). Without them the terrain draws the direct layer blend and the ballast shoulders are lost. Called by WrapMaterialAs; nothing is changed, it is the buyer's material.

Parameters

Name	Type	Default	Meaning
`Parent`	`UMaterialInterface*`	—	Any surface material or instance; null is not ready.

Returns

True when both hold.
