Thx for the quick answer! I checked both: in JO Shadow Troopers stealth effect is different - he's just transparent with some strange highlights; in JA Saboteur have 2 effects when he's hiding - first same as Shadow Trooper, but in few seconds he becomes completele invisible with displaement - exactle what i've needed!
I've found Shadow Trooper stealth effect ("cloakedShader" in assets1.pk3/shaders/effects.shader)
but can't find displacement effect anywhere
Can you point where I should search for it?
