Hello Ümit,
I am trying to effect the components of scene with green light. Although
green light could effected two of sphere, couldn't get success on the
terrain model. What can I do to effect the terrain with green light?
Your terrain's texture is probably being applied in GL_REPLACE mode,
instead of in GL_MODULATE mode. In GL_MODULATE, the texture color is
multiplied by the shading value at a pixel to give the final surface
color, and in GL_REPLACE mode the texture color is used directly
(replacing the shading).
Your options:
* Check the terrain model file (you can try osgconv model.whatever
model.osg if it isn't an .osg file, and then open it in a text editor to
check for the texture application mode) and change it in the model.
* Write a NodeVisitor that you will run on your terrain model after
having loaded it to change any osg::TexEnv object from REPLACE mode to
MODULATE mode (or just remove the TexEnv, since the default is MODULATE).
I recommend option 1, your life will be much easier if your models are
correct in the first place and you don't have to hard-code any changes
in your program.
