SFML projects / Re: SFML Light System - Let There Be Light
« on: March 22, 2014, 07:53:25 pm »
EDIT:: Fixed the errors by doing:
Going true posts and getting "lightAttenuationShader.frag" that doesn't make errors,
There is still a issue of light not being rendered when the light is "left of hull", everything works fine but the light when it is left of the hull, the hull is not rendered at all...
EDIT::Ignore Fixed, use for code if want its working, but the light Point 2 is broken.
Thank you, including openGL fixed that error.
But i am getting very bad visuals and console errors with "what i think is the user updated latest example code"
"Console screenshot"

Any ideas why there is an "openGL" failure, my gpu drivers up to date and same issue.
Also why the "Point light" gives error ("Cannot create texture invalid size(50, 0)"), i tried messing up with the code and i cannot make it work.
