No 'without' shouldn't be darker actually... Just there are two green regions on my underlying texture (darker and lighter)... like grass on the football field... Just one screenshot (that is without transparency) I took when I was on the darker region of the underlying texture and another one (that is with transparency) I took when I was on the lighter region of the underlying texture... Just assume that the brigthness of the underlying textures are the same on the both parts... I'm wondering why with transparency my WHITE line is GREY and at the same time without transparency it's WHITE...
