Masking Shaders Pack

This pack contains 4 Shaders that let you mask multiple textures in various ways.
1) MultiTextureLerp: This shader takes 3 Textures and dependent on the First to Second texture Lerp value and Second to Third texture Lerp value, shows only 1 of the 3 Textures or any 2 or even all three of the textures in the same material.
2) MultiTextureLerp_4Textures: This shader is a 4 Texture variation of the MultiTextureLerp shader.
3) DualTextureOverlap: Takes 2 Textures; one acts as a base texture and other as an overlapping texture which has Alpha. The overlap Texture basically acts as a pattern drawn on the base Texture. Both the textures can be given their own colors as well. Do be careful when applying on complex models, to carefully fit the overlapping Texture within the UV boundaries.
4) TextureMask: TextureMask takes 1 main texture and one Alpha texture that masks off parts of the main texture. The main texture can ideally have Alpha within it too and can be useful for decals or patterns within the same material. As an added feature, you can also rotate the main Texture in Radians.
