Chaos Corona for Cinema 4D => [C4D] I need help! => Topic started by: Schlee on 2021-03-05, 16:13:23

Hi all
We chose Corona Renderer because we want to visualize many of our products in 3D.
We are desperately trying to get a pure white background. The white background should not have any light shadow influences, only the ground should have shadows (and preferably no light influences).
Besides, the result is much too overlit - I guess because the background reflects the light.
Attached is a picture of us and one of how we would like it.
Also a picture of our setup.
What is the best way to do this?
A PURE white background without any light and shadow influence (only on the floor shadow of the object)
Many many thanks

You can't really get a pure white background straight out of the render, you need to do it the same way as photographers in real life. You get the product well lit and looking right, then in post you adjust the background to pure white.
The good part is that you can set up masks for just about anything in your scene, which makes post that much easier.

Thank you for your reply ficdogg
To adjust post render you mean in Photoshop or Lighroom?
Regarding masks - what do you mean exactly? Basically something like to Render with a transparent background? :)
Many thanks

There's no reason why you couldn't pull it off with Corona alone. It's really simple setup. I'm a 3ds Max user, so instead of trying to explain it in words, i'm attaching a screengrab with some explanations. Hope this will be clear enough.

Hi romullus.... you are the King! :)
I am still trying to catch all you have shown in yourt explanation as I am very new to Corona Render :)
What does mean Map #17 and Corona Bitmap are these two materials to be applied?
Does the green points on your screen mean only this needs to be active?
In Cinema 4D Corona Render setup I don't see a "Single map" - any C4D user which nows where to find it?
Many many thanks!!!

BTW if there is any Hero here who could help me to setup this lighting by sharing my file, I am also ready to pay for this couple of minutes..... getting desperated :-)
Enjoy the Weekend

Map #17 is CoronaColor texmap set to whatever colour you need for the background (in this case - pure white).
CoronaBitmap contains HDRI, which is used for scene lighting (could be ommited if you're using other means to light your scene).
Green dots are just a part of 3ds Max's UI, they show which maps are connected to which slots.
I don't know how much C4D UI differs from 3ds Max, so i can't help you much more than that, sorry.
-
Unless I did something wrong, this should be the setup for C4D (minus a material with an HDRI that would go in the scene environment slot).

Hi Cinemike, thanks for the effort!! If opening I get the massage "faulty file structure" probably because I use older C4D version (R18) ?
attached just in case my model :-) - love this forum :)

@Schlee
I don't think it's the C4D version but the Corona version. Which one do you use?
-
I used R18 and Corona V5 for this file, I think you should be able to open that now.

And big thanks to romullus, it's his words, I am just the interpreter.
