I probably missed something. Also there's some hackery when loading 3D models, which are still assumed to be in metres. --- gfx/gl/shaders/pointLight.vs | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'gfx/gl/shaders/pointLight.vs') diff --git a/gfx/gl/shaders/pointLight.vs b/gfx/gl/shaders/pointLight.vs index b3fe7b9..7694a25 100644 --- a/gfx/gl/shaders/pointLight.vs +++ b/gfx/gl/shaders/pointLight.vs @@ -13,6 +13,6 @@ void main() { centre = position; - size = (8 * sqrt(max(max(colour.r, colour.g), colour.b))) / sqrt(kq); + size = (8000 * sqrt(max(max(colour.r, colour.g), colour.b))) / sqrt(kq); gl_Position = vec4(centre - viewPoint, 0); } -- cgit v1.2.3
