Can someone tell me where is texture solid button in 2.77? I cannot find it anywhere. I cannot see it in Shading menu.
The shading panel's options are Mode dependent.
Means,Every shading mode has his own option,Texture Solid is one of the Solid Mode option so you have to be in Solid Mode to enable it.
If you notice on the dock below the viewport screen it says what mode your in. I'm in object mode. Next to it there is a white circle. Clicking on it will show your options on how to display the objects. after clicking on a drop-down (or drop-up) menu will appear.
Click on Texture. Done!
