Member Data Documentation

bAffectedByComponentScale

uint32 FStreamingRenderAssetPrimitiveInfo::bAffectedByComponentScale

Mesh texel factors aren't uv density and shouldn't be affected by component scales

bAllowInvalidTexelFactorWhenUnregistered

uint32 FStreamingRenderAssetPrimitiveInfo::bAllowInvalidTexelFactorWhenUnregistered

For mesh components, texel factors are their sphere bound diameters that are 0 when unregistered

Bounds

FBoxSphereBounds FStreamingRenderAssetPrimitiveInfo::Bounds

The streaming bounds of the texture/mesh, usually the component material bounds. Usually only valid for registered component, as component bounds are only updated when the components are registered. otherwise only PackedRelativeBox can be used.Irrelevant when the component is not registered, as the component could be moved by ULevel::ApplyWorldOffset() In that case, only PackedRelativeBox is meaningful.

PackedRelativeBox

uint32 FStreamingRenderAssetPrimitiveInfo::PackedRelativeBox

When non zero, this represents the relative box used to compute Bounds, using the component bounds as reference. If available, this allows the renderable asset streamer to generate the level streaming data before the level gets visible. At that point, the component are not yet registered, and the bounds are unknown, but the precompiled build data is still available. Also allows to update the relative bounds after a level get moved around from ApplyWorldOffset.
