In the High Definition Render Pipeline (HDRP) you can use Streaming Virtual Texturing (SVT) in Shaders you create with Shader Graph.
SVT is built on top of Texture2D. SVT Textures go through the same importer, which limits the maximum texture size. SVT doesn’t support textures larger than 16K x 16K. It also does not support UDIM Textures, or merging tiled image files into one large texture.
SVT doesn’t support all Texture graphics formats. The supported formats are:
GraphicsFormat::kFormatRGBA_DXT1_SRGB
GraphicsFormat::kFormatRGBA_DXT1_UNorm
GraphicsFormat::kFormatRGBA_DXT3_SRGB
GraphicsFormat::kFormatRGBA_DXT3_UNorm
GraphicsFormat::kFormatR_BC4_UNorm
GraphicsFormat::kFormatRG_BC5_UNorm
GraphicsFormat::kFormatRGB_BC6H_SFloat
GraphicsFormat::kFormatRGB_BC6H_UFloat
GraphicsFormat::kFormatRGBA_BC7_SRGB
GraphicsFormat::kFormatRGBA_BC7_UNorm
GraphicsFormat::kFormatR8_SRGB
GraphicsFormat::kFormatR8_UNorm
GraphicsFormat::kFormatR8G8_SRGB
GraphicsFormat::kFormatR8G8_UNorm
GraphicsFormat::kFormatR8G8B8_SRGB
GraphicsFormat::kFormatR8G8B8_UNorm
GraphicsFormat::kFormatR8G8B8A8_SRGB
GraphicsFormat::kFormatR8G8B8A8_UNorm
GraphicsFormat::kFormatR16_SFloat
GraphicsFormat::kFormatR16_UNorm
GraphicsFormat::kFormatR16G16_SFloat
GraphicsFormat::kFormatR16G16_UNorm
GraphicsFormat::kFormatR16G16B16A16_SFloat
GraphicsFormat::kFormatR16G16B16A16_UNorm
GraphicsFormat::kFormatR32_SFloat
GraphicsFormat::kFormatR32G32_SFloat
GraphicsFormat::kFormatR32G32B32A32_SFloat
GraphicsFormat::kFormatA2B10G10R10_UNormPack32
SVT는 다음을 지원하지 않습니다.
SVT의 텍스처에는 타일 크기(128x128픽셀)보다 작은 밉맵이 없습니다. SVT는 샘플링을 이 밉으로 고정하므로, 멀리 떨어진 특정 콘텐츠의 경우 앨리어싱이 보일 수 있습니다.
SVT only supports trilinear filtering in the Player, and not in the Editor.
SVT only supports streaming from disk in the Player, and not in the Editor.
The maximum anisotropic filtering level is 8. This is because each tile has an 8-pixel border.
You cannot set Textures that are part of a stack dynamically in the Player. In the Player, you cannot call Material.SetTexture
or Renderer.SetPropertyBlock
to modify the Texture Stack.
