Title: Autolight!
Post by: Cinemike on 2019-09-02, 21:33:04
I watched a Max tut and there's an autolight active until you create a corona one.
Can we have this for C4D, too?

That's a Max thing, depending on how you ask it to light the scene, and not a Corona thing :) (Max has some "default lights" at times, for illuminating the viewport - if you mean something other than illuminating the viewport, let me know!)

I mean C4D's autolight that lights the viewport and also serves as an automatic simple light when rendering.

Now, that doesn't happen in Max - if there are no lights in the scene, Corona renders black :) Even if the default lighting is illuminating the Max viewport.

So there is prpbably a light in this
tutorial that was set before (sorry, I am not familiar with the strange Max viewport).

I still think that autolight would be nice.

You mean Cinema's "Default Light" when no light source is present, which is read (picked up) from OGL viewport for integrated render engines (AR, Physical & RPR)?

Yep, there would be scene lights set up there. Not sure if Corona would have access to the "magical not really there" lights used in the viewport, since it doesn't in Max, that may be for good reasons (even for keeping functionality the same across different apps, I guess if it was to be added in C4D it would have to show up in Max too, so that Corona works the same and is familiar whichever version of it you choose to use, meaning you'd have to convince the core team that there was good reason to have this ;) )

It's Optional & could be same kind of checkbox preset or an 'extra' object in Corona's menu.
Made from a single spot light, picking lighting location/direction from the "Default Light".
All other values/attributes are predefined since they cannot be modified by the user.

BTW, ProRender's "Default Light" doesn't pick any changes from it, but always stay on 'Factory' settings ;)

Guess I need to agitate the Maxers then, too!

I really, really, really still want this.
Redshift has it, too, getting on par with the competition should be important!

I am trying everything here ;)

To be honest I dont think this is a good idea.

There is also an extremely simple solution - in an empty project just add a sky with the most neutral HDRI you can find (I use the uffizi one that www.corona-materials.de uses). Than save that file as your default scene. Bingo! Now you have a default light in every scene you create.

I do something similar as well. I saved a scene as ''new.c4d'' with a Corona Sun and sky and adjusted the exposure for the camera. Now every scene loads with this and I'm ready to go ;)

I will bring it up again in Summer 2026, unless a miracle happens by then.
