System Information
Mid 2009 13" MacBook Pro 2.57Ghz(I think) dual core something or other, running windows 7

Blender Version
Blender 2.71 Hash: 9337574

Short description of error
I have a diffuse texture and a emit texture that are different. In rendered viewport shading the material emits the diffuse map. Also, the emit material does not export to fbx, even as the diffuse.

Exact steps for others to reproduce the error
1-Unwrap the default cube by hitting U and selecting Cube Projection. Separate the faces in the UV/ImageEditor
2-Create a new image and draw numbers on each face. Apply image to first texture slot of the default Material, and set Mapping Coordinates: to UV, and Map: to UVMap.
3-Create another new image and draw lines across it. Create a second texture slot on the default material and apply this image to that. Set Mapping Coordinates: to UV, and Map: to UVMap. Uncheck Color. Check Emit.

In the rendered viewport, the Diffuse texture will emit. If I turn off the Emit texture the diffuse map acts normal. If I turn off the Diffuse texture and leave on the Emit, it emits pure white. If both are turned off it is your normal grey cube.

I noticed this trying to export a material with an emit map in fbx format for use in UDK. Normal maps and Diffuse maps so far work fine, but that is all I have tested so far.

I hit pack textures as .png presuming that might save them inside the .blend file. Seems like the logical thing for that to do. If not they are simple to recreate based on the instructions above.

Lets keep issues nice ordered, and consider Blender case (rendering) here.

If you think there is an issue with emit textures in FBX export, please make a separate report (afaik, they are exported as expected).

This is not bug
Go to texture settings, switchoff use alfa - and all will be properly - your cube is all white because you created texture with full alfa, switch off "use alfa" or go to image editor, select erase alfa, draw anything, then render - cube will not glow in places then you painted you can switch on or off diffuse texture - working will norm. But your textures is not so visibly,
look this{F102981}
switch on diffuse texture, and one of two others(alfa emit map and rgb emit map).
you can cwitch off this diffuse texture, or create new, create a lamp(i was delete it), and do anything else - all working properly!

@Inwader77 nice catch, thanks! :)

@keithk thanks for the report, but no bug here indeed.
