I want to keep the settings except emission and only change the strength of it like the emission node. Any ways?

You can manually input values higher than 1 in the red,green,blue fields of the emission color of the principled shader. Keep in mind that this is a workaround and will not mimic exactly how a classic emission shader works when you tweak its strength.

enter image description here

For ease of use you can use such a setup : Add an rgb node in order to input the exact color you want the emission to be, a value node for the strength of the emission, and link both of them to the color inputs of a mix rgb node set to multiply with a factor of 1, then set the output of the mix rgb to the emission input of the bsdf.

Try adding a mix shader. Be aware that your Prinipled BSDF emission should be set to black (none) so as to not influence the emission shader

  • $\begingroup$ I'm worried about that 'factor'. Doesn't it make all other things(Base color, Subsurface and so on) dim and weaken their influence if it's set lower than 1? $\endgroup$ – 김준형 Jan 17 at 12:41
