Textures are missing, but only when I render I was trying to make an animation but for some reason when I try to render it or just go into render view the materials are all pink.
I seen other posts about a similar problem of the textures not being linked to the file or whatever but that's not the issue, the textures appear when I'm in material view. I have it set to render using CPU in my user preferences. This is happening for all my projects in Cycles render. The few projects that I made in Blender render when I first began do not have this problem.
You might move your textures or renamed it
So u just replace it in same location or use external data/find missing files feature
When u want to  email it just some one just pack all textures by this feature external data/pack all files
