How do i use a trigger box to make an invisible mesh to appear and then disappear after a minute or seconds.

[TheOGHyper]

i need to do it in blueprints.

First of all, Appearing Box need to have dynamic material. Im doing this through custom function.

Function:

Material:

Then you need to flip on/off physics of disappearing box and so on.

i am still confused on what to do on this

[Tonakien]

You need:

*) Target for Dynamic material creation → Mesh of your appearing box
*) You need to pass created Dynamic Material to nodes that manipulates it parameters (crefully look at screens I gave. Notice connections)
*) Parameter name to set color if you need this. If not just tond use it
*) Parameter for opacity

Appearing box material should have parameters you are calling

for some reason i can’t get the transparency thing because the image on the mesh is png background and i need the background invisible but what i am trying to do is make the mesh invisible and when i walk into the trigger box it puts a delay for 5 minutes maybe and then it shows the mesh appear and then a few seconds it goes invisible. like somehow a jumpscare from a distance.

@TheOGHyper

mesh is png background

Didnt quite get this part. It is the same png as the background? If so make a duplicate and manipulate it.

i put a png photo of a character on a plane mesh and i made it look like a character but its 2d.

Ok. There is another way.
In Mesh details there is a parameter “Hidden In Game”
Call it “true” when you need to hide Mesh

ok and then i make it appear after a few minutes when i move through a trigger box and then a few seconds disappear.
