Hi, this question might be tricky.
I’m trying to make a set of painting tools but with these jars I’m facing a problem.
You can see clearly on the green one that some paint inside is “rough”. This is because, inside, the paint has bumps, since I was meaning these jars as available to be also opened (I’m aiming to sell it).
But here I get of course the effect of the internal normal map also when seen from outside.
I’d like to be able to find out a workaround to make it visible only when seen from inside, but I’ve no idea about the how. I also get double reflections in the glass as you can see, there are 2 rectangles of light while the source light is 1.
The IOR of the glass is 1.450… and the Glass shader is just mixed with the Principled shader (again with 1.450 IOR). Simple material…
The last solution is to erase away the normal map effect inside but I’d like to keep it if possible…
