Greetings im working on a VR project where the users are supposed to assemble an object.
I wanted to recreate something like in this video Virtuademy - Virtual Reality training: gameplay Olivetti VR - YouTube so when the user picks object A a wireframe version of that object would appear in the place where it is supposed to be assembled once the user fits it in that place that wireframe version of the object would disappear. How i do this?
Best regards,
It’s not wireframe, it’s just the same model/mesh, but with a translucent material

Combining wireframe (in case you actually do want it) with fresnel produces this super simplistic yet somewhat convincing effect:
It may not look good on some meshes or you may not like it. For something more nuanced, search YT for ue4 hologram materials, scrub through some tuts to get close to what you need and adjust accordingly.
How i do this?
Are you asking about developing the whole system for that? If so, what do you have working atm?
yes im asking whats the logic of blueprinting it.
i already have the objects being placed to the main body, but now when i pick object A i have to see it duplicated with that hologram material and already fit in the main body and then make it disappear once you fit that object in place.
Spawn a new object with the see-through material and postion it as needed.
To make it disappear… not sure how you’re moving things atm, either of these should work:
• detect it with the mouse cursor as you move the real part
• use overlap when you move the real part
• use overlap when you move the ghost part
If in doubt, post existing script so we can suggest something that fits into you system.
