What do you think about my PMMA clear shader?

Do you think there is a way to have a more acurate shader? With nodes or Cycles improvment? :nerd_face:

Define “more accurate”. What is it about the material you have that you are unhappy about?

3

I mean more “real life acurate” with pmma

I dunno, looks pretty good to me. You could tweak the IOR.

Why do you believe is doesn’t look accurate?

it looks good, but I don’t know well Blender, so I try to improve my skills…

What are you using as a reference for “good”.

When it comes to CGI you need to determine what “good” looks like and then aim for that.

Sometimes “good” doesn’t mean ‘photorealistic’, although even photorealistic is somewhat subjective.
