I tried to use an NK file from this site:
http://luxpop.com/RefractiveIndexList.html

I tried the chrome "Cr.nk" file but luxCore didnt accept the file and could not use it.

I checked my addons and I had an old addon from radeon prorender. I removed it.
Im still having an error message.

Yup, erroneous... didn't had much time to explore different standards in use... so for now,
this solution still applies.

Note:
Either .nk or .ior, use as Sopra. ;)

I just tried the site but the site is not working.
I searched for SOPRA files from the net and found one.
Maybe I can find more or convert LUXPOP files into SOPRA files by hand.
That site is here.

I did try those & none of them work out-of-the-box. Bad header and different description than expected so w/o a translator, they need to be adapted manually. And i have yet to dive deeper and discover what form is readable for LuxCoreRender.

Yes, I also got the error about a bad sopra header.
I cant figure it out.
