I've been searching for an answer for days now, but couldn't find anything.
Basically, what I would like to do is to pass a variable using the render tag to a snippet. Then edit the variable inside the snippet and pass it back. This used to work fine with the include tag.
Some more background information, to get more explicit:
I am using the Supply theme which includes a "image-logic" snippet. By default, this snippet is included in the "product-grid-item" with the include tag. However, I'm currently implementing a new feature that requires me to move it to the render tag.
