Cubemap

Create Cubemap and call CreateFromImages with six square Images. For the tested Vulkan path, face order is +X, −X, +Y, −Y, +Z, −Z, matching Vulkan cube-face order. GetLayers returns 6. Use face index 0…5 for UpdateLayer and GetLayerData.

An imported sheet must match its selected 1×6, 2×3, 3×2 or 6×1 layout. Face ordering does not replace correct rotation of each image contents. The map does not itself enable reflections and is not an ordinary UI Texture2D.

The complete sky shader below accepts Cubemap in source_panorama. It was checked by rendering six camera directions with distinct solid face colors.

shader_type sky;

uniform samplerCube source_panorama : filter_linear, source_color, hint_default_black;
uniform float exposure : hint_range(0, 128) = 1.0;

void sky() {
    // Adjust orientation only when the source face convention differs.
    vec3 eyedir = vec3(EYEDIR.x, EYEDIR.y, EYEDIR.z);
    COLOR = texture(source_panorama, eyedir).rgb * exposure;
}

Face readback, placeholder, binary persistence and this shader were checked. Solid test colors do not verify seams or orientation inside a face. These diagnostic pixels are not a graphics-quality illustration.

Declarations checked against C# SDK 1.0.0. Expand a name to see declarations and documentation.
