Materials Glow Query, UE 4.26

Is there a manner so as to add a cloth 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 variety of work for a easy impact.

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

There’s a technique you may arrange through Blueprint, the place it principally duplicates a skeletal mesh and mirrors the entire animations on it, which you should use as a type of “shell mesh” and apply a easy emissive materials with some world place offset to the verts (to push them out a bit of 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 through blueprint or anim curve, however if you wish to keep away from that it’s attainable to make use of the above technique.

I do know duplicating meshes is one thing that’s been prevented 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 manner in addition to these two, but when that’s my choices, then I’ll cope with them.

Thanks to your response

It actually simply depends upon the mission. When you’ve got one thing like Diablo or Darktide the place you’ve gotten dozens and even lots of of characters reside all utilizing that characteristic, the price will stack up fast. However if in case you have a recreation the place solely a small variety of situations can ever use it, like simply the primary participant, you have to be protected

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 use add or different mixing strategies, additionally you may 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 put up processing stuff with UE, however it’s one thing I do know I’ve to be taught. 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 every part 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 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

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. After all it depends upon the platforme.

Apply the stencil worth per object. The restrict is 255 distinctive stencils.
In principle, 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 information and sharing the screenshot examples

You may also append a cloth operate that handles the glow performance, you may arrange a map/DT preset of parameters that you may dynamically occasion via the blueprint.
