I am having trouble with emissions in my materials. How do I remove emissions? I am trying to model a simple room to make my sword model easier to understand (I was getting confused because the reflective material had nothing to reflect), but I cannot figure out how to make my wall material the right colour. I want the walls to be a bright yellow with small bumps on it. I attached a bump map and a normal map to the material. My trouble seems to be with the "emission" value in the "PrincipledBDSM" shader. I cannot get my bright yellow because of it. With the material colour set to yellow and emission set to black, I get a dark yellow. If I change the emission to yellow, I still get a dark yellow. I thought maybe I could change the alpha value of the emission but it seems to ignore the alpha channel. How do I get the object to follow a bump or normal map and let me chose the colour?

try setting the transmission on 0, and emission black
