Hi Unity community! I'm developer of AltSoftLab Team http://www.AltSoftLab.com In this post (http://forum.unity3d.com/threads/altsketch-graphics-library-c-freetype-port-gui-vector-graphics-etc.258920/) I presented our AltSketch Graphics Library. We need some help to implement some features in Unity using the best way. The second things we need is to implement multitexturing like DualTextureEffect in XNA or something else. A I understood we need a special (maybe custom) Unity shader for this trivial and widely used thing. I couldn't find a standart Unity shader with this technics. By our politics we try to realize our Hardware backends without any special and unique technics. It's to discard any limitations for AltSketch users (like hardware restrictions, etc.). All AltSketch Hardware Render Backends and Integrations are opensourced, so user can implement brushes realisations in any way he or she need. But we must to realize this feature in universal way. So please help me to make multitexture shader (or to find standart existed in Unity or somewhere else) with simple 2 texture blending withown Lighting and any other functions. Shader without any special restrictions. The scheme is very simple: Texture1_RGBA * Texture2_RGBA * Vertex_RGBAColor Thanks!
