basically I want to create a material effect like the cloak mode in crysis. I already tried the different transparency options for the material, but none worked out like i would like them to: I can either disable shading completely, or I have to live with the fact that faces are visible, that should not be:
I want it to look like this:
(not an actual screenshot - edited with gimp)
I figured out I need the scenetexture for this, but it only works with transparent materials. What I would do is: First render the scene without the cloaked object, then render the cloaked object with a solid material but textured with the scenetexture to make it seem transparent. Dependant on the percentage of cloaking I would blend between the scenetexture and another solid texture.
The question is: Is this possible? If so, how is it possible?
Thanks, by searching for UT3 instead of UDK I have found a few pictures/videos about the Nightshade's cloak and about cave crystals that look somewhat like what I want, but no hints whatsoever on how it is done
It is a material (VH_Nightshade.Materials.M_VH_NightShade_Skin). However there are two counter arguments: first I am not exactly sure if the material actually does what I think it does (all transparent materials from the udk or the ut3 demo do not) and second every online shop I checked so far said it wasn't available in my country so that is a bad omen I will still look it up at the local store tomorrow.
That looks pretty perfect
Yea I think switching Materials is a necessity. After playing around with the settings it is possible to blend from cloak to almost solid, but not entirely.
Still I will try to get ut3, seems to be a good idea- and sample-repository.
The idea is quite simple actually: Change the Blend to Alpha Composite. Then for a solid appearance set the diffuse to whatever it should be for solid. To have the material appear transparent plug the DestColor into Emissive and use the Distortion. The Cloaking-Effect is done by simply multiplying the two material 'types' with a factor:
By lowering the opacity parameter over time the cloak activates:
Not a final material, though, but I never thought I get this proof of concept done so quickly. Thanks alot to everyone!
