Materials Glow Query, UE 4.26

Is there a approach so as to add a fabric 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 might presumably be modified, however that additionally would entail loads of work for a easy impact.

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

There’s a technique you possibly can arrange by way of Blueprint, the place it principally duplicates a skeletal mesh and mirrors all the animations on it, which you need to use 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 alter it by way of blueprint or anim curve, however if you wish to keep away from that it’s doable 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 verify to see if anyone knew one other approach in addition to these two, but when that’s my choices, then I’ll cope with them.

Thanks on your response

It actually simply is dependent upon the venture. When you have one thing like Diablo or Darktide the place you have got dozens and even a whole bunch of characters reside all utilizing that characteristic, the fee 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 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 need to use add or different mixing strategies, additionally you possibly can venture noises from digicam house 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, but it surely’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 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 making an attempt 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 normal materials, however you possibly can simply stack as much as 5 lighter supplies like this and get no efficiency points. After all it is dependent 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
