I saw topic with it, yep, solved. But with this coding:
material preset_10_maneMat
{
	technique
	{
		pass
		{
                       cull_hardware none
                       cull_software none
                       alpha_rejection greater_equal 128
                       texture_unit
			{
				texture xxxmane.png
			}
		}
	}
} I have better, but still not too good effect:

I mean, is it possible to solve problem with blocky mane things?
