Materials Glow Query, UE 4.26

Is there a means 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 making an attempt to do it simply with supplies. I do know I might change each single materials that would presumably be modified, however that additionally would entail plenty of work for a easy impact.

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

There’s a methodology you possibly can arrange by way of Blueprint, the place it mainly duplicates a skeletal mesh and mirrors the entire animations on it, which you should utilize as a form 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 combating).

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 attainable to make use of the above methodology.

I do know duplicating meshes is one thing that’s been prevented 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 means in addition to 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 mission. You probably have one thing like Diablo or Darktide the place you’ve got dozens and even a whole bunch of characters reside all utilizing that characteristic, the associated fee will stack up fast. However when you have a recreation the place solely a small variety of cases can ever use it, like simply the principle participant, you have to be secure

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

Calculate dot product from digital camera 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 possibly can mission noises from digital camera area for extra variations.

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

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

I don’t have a lot expertise with publish course of both, so I’m making an attempt to wrap my head round the way you go about proscribing or specifying particular person issues that the publish course of impact is utilized to

From the unreal documetation.

Hey are heavier than normal materials, however you possibly can simply stack as much as 5 lighter supplies like this and get no efficiency points. After all 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.

I figured it was one thing like that. Thanks for the data and sharing the screenshot examples
