Materials Glow Query, UE 4.26

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

I’m desirous to do some glows on characters and probably another meshes, and I’m attempting to do it simply with supplies. I do know I might change each single materials that might probably be modified, however that additionally would entail a whole 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 may arrange through 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 somewhat 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 regulate it through 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 an alternative. I got here right here to test 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 on your response

It actually simply will depend on the venture. When you have one thing like Diablo or Darktide the place you could have dozens and even a whole bunch of characters dwell all utilizing that function, the price will stack up fast. However you probably have a recreation the place solely a small variety of cases can ever use it, like simply the principle participant, you need 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 may venture noises from digital camera house for extra variations.

Thanks for that as effectively 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 study. 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 all the things 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 attempting to wrap my head round the way you go about limiting or specifying particular person issues that the publish course of impact is utilized to

From the unreal documetation.

Hey are heavier than commonplace materials, however you may simply stack as much as 5 lighter supplies like this and get no efficiency points. In fact it will depend on the platforme.

Apply the stencil worth per object. The restrict is 255 distinctive stencils.
In idea, 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
