I would love to be able to access materials that are giving errors through the V-Ray messages window, as Corona does in their message window.
You mean like a click on the message with a link to the material?
i requested this in the sticky about feature suggestions.
that´s a really good idea!
When you render in Corona, it’ll give you errors with links and clicking the link will populate a slot in the material editor. I am thinking when I merge something I’ll get the same type of thing. Often I’ll fill a space with furniture and decor, render and find weird things happen. Having a heads up when I merge would give me an opportunity to fix it right away instead of searching for the needle in the haystack.
