I don't understand why my model looks so ugly when I try to render it. Marmoset vs Substance

Wait 5 sec.

So I'm trying to make the final renders for this project, in Marmoset, and I have been at it for a few hours now. I tried different lighting set ups, and other things but it just looks ugly. I watched a few tutorials on how to set up everything but it still looks bad. Here I'll leave the render vs how it looks in substance painter (ignore the lack of eyes in substance) What am I doing wrong exactly? Render in Marmoset In substance painter viewport The last setup I tested https://preview.redd.it/n06pej4275rh1.png?width=294&format=png&auto=webp&s=c6cde929c6a4f82503da0876b2f77ae98a34e40a   submitted by   /u/Agile-Definition9127 [link]   [comments]
