Materials Glow Query, UE 4.26

Is there a method so as to add a cloth glow to meshes with out altering each single materials that’s on a mesh?

I’m eager to do some glows on characters and presumably another meshes, and I’m attempting to do it simply with supplies. I do know I may change each single materials that might presumably be modified, however that additionally would entail quite a lot of work for a easy impact.

So, is there a option to do one thing like this with out altering each single materials individually?

There’s a methodology you’ll be able to arrange by way of Blueprint, the place it principally duplicates a skeletal mesh and mirrors all the animations on it, which you should utilize as a kind of “shell mesh” and apply a easy emissive materials with some world place offset to the verts (to push them out a bit to keep away from overlap and z preventing).

Manufacturing-wise, it’s cheaper from a efficiency standpoint so as to add the glow in your grasp character/prop materials and alter it by way of blueprint or anim curve, however if you wish to keep away from that it’s potential to make use of the above methodology.

I do know duplicating meshes is one thing that’s been averted purposefully, so I’ll look into doing that as a substitute. I got here right here to verify to see if anyone knew one other method moreover these two, but when that’s my choices, then I’ll take care of them.

Thanks to your response

It actually simply relies on the challenge. In case you have one thing like Diablo or Darktide the place you may have dozens and even a whole bunch of characters dwell all utilizing that characteristic, the fee will stack up fast. However in case you have a sport the place solely a small variety of cases can ever use it, like simply the primary participant, you need to be protected

You are able to do it as a post-process impact materials utilizing stencils

Calculate dot product from digicam to world regular and also you get the fresnel gow, set it with an influence node for finer tuning then mix it with the ultimate body.
I used overlay mix, you should utilize add or different mixing strategies, additionally you’ll be able to challenge noises from digicam area for extra variations.

Thanks for that as properly and the instance. I don’t know an excessive amount of about put up processing stuff with UE, nevertheless it’s one thing I do know I’ve to study. Is put up course of materials efficiency heavy?

I’m guessing you simply specify what receives the put up course of primarily based on its stencil worth, in order that it doesn’t get utilized to the whole lot that’s utilizing that materials as a mother or father? Or would this want an unique materials mother or father per object you need to have an effect on?

I don’t have a lot expertise with put up course of both, so I’m attempting to wrap my head round the way you go about proscribing or specifying particular person issues that the put up course of impact is utilized to :confused:

From the unreal documetation.

Hey are heavier than normal materials, however you’ll be able to simply stack as much as 5 lighter supplies like this and get no efficiency points. In fact it relies on the platforme.

Apply the stencil worth per object. The restrict is 255 distinctive stencils.
In concept, you cod have 255 distinctive post-process materials results in-game for varied actors.
