Question by Kevin Laity · Jan 05, 2010 at 06:29 PM · shadermovietexture

Movie Texture Blending

When writing a shader, for some reason if I try to blend using a MovieTexture, the blending gets ignored. I'm trying to use one movie as an alpha channel to another movie.

I've tried all the built in shaders Unity comes with, but none seem to work properly with MovieTextures. Is this even possible?

Is there a shader out there that's known to blend movie textures properly?

I have the same problem in Unity 5.1. I only see a transparent plane. Therefore I uploaded a simple unity project (ZIP, 123$$anonymous$$B): https://www.mediafire.com/?nz9yx2ae4bh13fo

I used the movies of voncgoh.

Here is a Screenshot of the Project:

It would be great if someone could edit and reupload the project.

Anyone with a sample project file? I tried the script but get total transparent material even in preview within Unity Inspector. I use After Effects to output the Alpha quicktime in H264.

Just to confirm in case it is reverse, White is to show and Black is transparent, right?

I uploaded the C# scipt, shader file, ocean.mov and mask.mov to $$anonymous$$ediaFire. I am reading up on shader to understand more.

The set-up is just a simple plane + script and a material with the shader, right? Somehow, I am not getting it to work.
