So, (Please note, that i am starting out in blender, and only know the Basics) When i rendered it, N's face was all... I honestly don't know, How do you fix that?
hey i was just like you and still am tbh but the easiest way i found to do it is if you go to the shading tab at the top. select the face panel. then were it says like IOR and alpha, slide alpha all the way down to 0. when you render it should look correct. then for the armband being red, i changed one of the color things to vector and it worked. if it doesn’t work for you then just mess around with the settings in shading. Hope this helps!
Don't worry, it's not your fault (neither mine). The most recent versions of Blender use a new version of the EEVEE engine, which causes this problem, so far the only way I've found to solve this (not in all cases, I think) is disabling some ray tracing denoising options like "Spatial Reuse" or just disabling denoising completely.
