Unity Script Reference – Cubemap.SetPixels

Cubemap.SetPixels

function SetPixels (colors : Color[], face : CubemapFace, miplevel : int = 0) : void

Description

Sets pixel colors of a cubemap face.

This function takes a color array and changes the pixel colors of the whole cubemap face. Call Apply to actually upload the changed pixels to the graphics card.

The colors array is a flattened 2D array, where pixels are laid out left to right, top to bottom (i.e. row after row). Array size must be at least width by height of the mip level used. The default mip level is zero (the base texture) in which case the size is just the size of the texture. In general case, mip level size is mipSize=max(1,width>>miplevel).

This function works only on ARGB32, RGB24 and Alpha8 texture formats. For other formats SetPixels is ignored.
