I would like to make a rontgen film pass over 3d text and make a scan effect. I don’t know if I have posted this
in correct group so correct me if I’m wrong. So if anybody can explain me how could I do it, or at least point me in
right direction it would be appreciated.
An X-ray effect (or at least that’s what google tells me :P)?
For text? (what good would X-rays do if text is typically a solid object? Is there hard and soft parts to the text?)
Could use post an image of what you’re thinking about? I don’t think I can quite visualize you’re asking for.
[accidentally clicked new post instead of editing my first one]
Something very basic to start with…
Film is a glass material, with refraction set to 1 so image seen through it doesn’t distort. (Has to be glass, otherwise rays passing through it don’t seem to count as transmission.) Object behind the film gets a shader mix, factor input has Lightpath>IsTransmissionRay as factor input. Slot 1 on mixer gets shader for what is seen without film in front, slot 2 shows shader for whatever is seen through the film.
If you’re clever with something like texture maps, you should be able to figure out the rest. 
—Edit—
After playing around a bit, I found the effect is kind of cool and perhaps versatile. It was too tempting to make a video covering how to do it, so I did.
Yeah :yes::eyebrowlift2: thanks, that’s just what I had in mind, fantastic I want to add it in animation, so yes, that plane (film) should just pass over the text, just as it would pass through the monkey head. How could I add some small interaction effect beetween them, like some small lightning or some small fireflies, just something on what I could later add some audio buzzing effect?
And I’m trying to make the bezels-edges of the film to be like this:
but I can’t find first and last node from this picture:
this was not done with composite (might be possible )
it was done in cycles nodes !
let me know if u want it
happy cycles
Well yes, I would like to see and learn cycles nodes and see how it works, but if someone could explain me how could I make that or something similar in cycles that would be appreciated, because I have the whole scene done in Cycles and that animation is the last part, so I would like to finish it in Cycles.
Thanks
