Non-Physically based rendering features

Hi guys. First of all congratulations for the amazing work on Corona.
It's getting better and better each day.
Looking forward to the release of 1.6 update.

It would be so nice to see some features that allow us more artistic freedom.

For example. If I want a Corona Light to not affect the diffuse, reflection or refraction of a specific object I don't have a way to do it.
Or if I would like a light to illuminate but not cast shadow on a specific object, I can't find a way to do it either.

My suggestion is that on the side of the "Visible in reflections" and "Visible in refraction" we could have a list of objects where we could include and exclude them.  Vray also added an option where you can choose in a scale from 0 - 1.0 how much effect this light will have on specular and diffuse, which is also very useful in some cases.

It would also be good to have a "Visible in diffuse" option.
And the last thing I miss is an option where you could select an object and say if it will affect alpha channel or not. This is a simple option that I used to check a lot on vray object properties and that I miss in Corona.

These options seems kind of silly when many artists look for realistic results, but sometimes we need more freedom to work in complex and non-realistic scenes.

Hi, thanks for your requests. Generally Corona is intended for photorealistic rendering, and adding "fakes" usually means that sooner or later something will break, so it's always a challenge. But each feature request is checked, so it is possible that our developers will consider yours too.

As to "an option where you could select an object and say if it will affect alpha channel or not" - not sure if you are aware of this already, but you can control whether specific material is visible to the alpha channel and/or masks by using the "alpha mode" and "visible in masks" settings in the material's Advanced options rollout.

Hi Maru,

Thanks for the reply!
I understand!
It would be great to have these features but it makes sense that they are not easy features to implement and at the same time keep things working as they should.

About the option in advanced rollout, I'm aware and testing it.
Thanks a lot.
