Emission on steel from laser cut

You can achieve this effect by using the dynamic paint system. Select your steel plate and give it a dynamic paint physics modifier, set it to be a canvas. Then set your laser object to be a dynamic ...

How do I change strength of emission at Principled BSDF

Blender 2.92 + : In the newer versions the principled BSDF shader actually has a field for emission strength, right below the emission color field. You can use it much like the simpler Emission Shader....

Emission: Red glow while the object itself is white

From a physically based rendering point of view, the problem you are running into is that Blender's HDR tone mapping is trying too hard to be helpful. The effect you see in the reference image occurs ...

How do I make emission pass through something like it is underneath a cloth?

What you're asking for is called translucency. There's a Translucent BSDF available in Cycles (not to be confused with Transparent BSDF) which you can use in conjunction with other nodes. Here's a ...

Images as emitters constantly come out dull. White emission not actually white. What am I doing wrong?

Set the color management as standard instead of filmic, and read this answer for detailed infos. Render with a wider dynamic range in cycles to produce photorealistic looking images

How do I texture paint with glow?

It has nothing to do with the painting per se. First, you need to paint the emission map of your shader : Make sure to use black as blank color when creating the texture, so it doesn't emit light ...

Emission wont emit through black colour screen

Reframing the idea behind “Alpha” as occlusion should make the idea clearer, where “Transmission” is a degree of filtration. The 0.0-1.0 range in alpha represents the degree of occlusion from 0% to ...
