Sorry if this is a dumb question; but I’m trying to learn normal mapping in blender internal. Problem is, the output from the 3D preview window using GLSL is quite different from the final render and this makes it very hard to predict how the final image is going to look like.
For the screen cap below, I loaded a PNG with transparency (by importing an Image as a Plane) and I just clicked on “Normal Mapping” on the right. I know I have to use a normal map; but the problem is the same, so I figured that step was unnecessary. My guess is that I have to enable the final render to use GLSL; but I don’t know how to do that.
I would appreciate any suggestions, thanks.
