I've created another scene using a pocket watch not created by me, but perfect for showing and explaining what I'm trying to achieve. The pocket watch has a better surface a nice lid with glass which helps with trying to illustrate the issue.
The link for the file is below.
If I use thin wall glass then we get no refraction.
But I get close to the desired effect. Refraction is still needed to make the scene right.
Using thick wall glass I get the refraction but loose transparency.
I've put some random objects in the background for illustrating the issue.
I have tried various glass surfaces with no luck.
It would have been so simple if the 0 - 100 was enabled for the environment tab
I've included two renders to save rendering the file of what the outcomes are.
Thanks in advance! and thanks for the replys so far!!!
