Is it possible to make a mesh transparent without changing its material?
I have a telekinesis spell in my game, it functions like Half-Life 2's physics gun.
I would like to make the grabbed object to become transparent. I know how to do it by changing its material, but my question is, is there any way to do it without changing the object's material (which most often is BLEND_Opaque)?
I tried hiding/un-hiding the mesh in the Tick event, but it's not fast enough to look nice.

Hey lxiguis -
While the Opaque Blend Mode will not allow you to get the type of quick fade out you are looking for you can use the Masked Blend Mode and a setup like below to do a faux fade out:
Here is all you would need in the Opacity Mask Channel:
Here is the Effect Running:

Could be better if you create a Material Instance from the Actor´s Material, create a Material Expresson constant, with value 1, and make it as a param of the Material Instance.
In you blueprint, just change the value as you need, could be using a timeline for example.
