MakeChannelPackedTexture

TextureUtilities.ChannelPackColors()

public static Texture2D MakeChannelPackedTexture(
  Texture2D textureRGB,
  Texture2D textureA,
  TextureUtilities.PackingResizeIfNotSameResolution rescaleType = TextureUtilities.PackingResizeIfNotSameResolution.ScaleToFirstTexture
)

Parameter	Type	Default	Description
textureRGB	Texture2D		RGB Texture containing 3 channels (Red, Green and Blue). Alpha is on the 2nd Texture parameter
textureA	Texture2D		Alpha values
rescaleType	TextureUtilities.PackingResizeIfNotSameResolution	TextureUtilities.PackingResizeIfNotSameResolution.ScaleToFirstTexture	What kind of rescale to apply in case one or more textures have different resolutions

Returns: The Channel Packed Texture

Channel Pack 4 channels taken from up to 4 different textures (1 channel each).

Example Usage

using UnityEngine;
using MikeDaBird.EZRecolor.Utilities;

class RotateTexture : MonoBehavior{
  public Texture2D textureColor;
  public Texture2D textureGrayscale;

  // Rotate a texture by a rotation, both set within the Component
  public Texture2D PackTextures(){
    texture = TextureUtilities.MakeChannelPackedTexture(textureColor, textureGrayscale);
    return texture;
  }
}
