[Book1] Issue rendering dielectrics (hollow sphere)

[jravi7]

I am following along book 1 and encountered issues with dielectric rendering. Here are my renders:

Another issue I noticed was that the order of spheres added to HittableList objects affects the final render. I have the center sphere added second to the list (just like in the book) and it is rendering below the side spheres (similar to layers in image editing tools). Is this a known issue for all?

Here is a link to my repo - https://github.com/jravi7/raytracing-in-a-weekend

Found the issue. I didn't update my tmax for subsequent hits in my hittableList Hit method. This solved both issues.

This discussion made me take a look back at my hittablist's Hit method. Although the issue was different, I did find my mistake in the code.
