Yes, I know it is not hard to imagine. All of us can do it. But having specific scenes, examples, and knowing what users are actually doing is another things. This always helps us prioritize things and allows us to better understand what the users are doing, what solutions they need, and why.
How you will understand it, when it is not even in voting list?
A lot of stuff we can do with this feature. A lot of us need this feature for sure. What is the point of Corona in Cinema 4D, when users use Cinema for some animation? I thought Alex Roman did write some needed features for Corona after his project in this engine.
It is always better have some possibilities, then do not have it and use other engines. As we know, V-Ray has this feature, but when I did one project with a water, I did use Arnold render, not Corona or V-Ray, because it is more simple to set up, then V-Ray. And Corona hasn't this possibilities at all. If somebody think, that people will go for some features to V-Ray instead Corona, it is not, we have another engines for this.
Still waiting for this feature in Corona, still waiting when developers start listen community and will not ask why we need this feature or that. We just need it. Create a vote for a start.
