What is the best way to use Backplates in Corona C4D?

(1/3) > >>

ShynnSup:
I am not sure how to approach this.Maybe there is no 'best' way just different ways but I still wanted to ask for the standard way of doing it...

I understand I can use 2 different HDRIs (can be the same color corrected) one for lighting and one for background. This is easy to do with the checkboxes in Corona Sky object.

But most backplates are planar JPGs:
Should I just use a plane and apply a material with the JPG in diffuse channel and use frontal or flat projection?
Should I use a Background object?
Should I use another Corona Sky object with projection set to frontal? I think this might be the one no?

Thanks

Atlantis:
The "official" way to do it is probably via Scene environment. Create a Corona material with your jpg image and drag it into the required field.
Or you can create a Cinema 4D material and drag it to a background object. (although I got some render errors with this method lately)
I still use the C4D method to see the image in the viewport.

Hi, there are a few steps needed for this.

1. Create a plane object and add a shadow catcher mat to it and add your ''backplate'' image.
2. Add a Corona sky object and assign your HDRI to it.
3. Create a Corona light mat and disable ''emit light'', add the ''backplate'' image to it.
4. In the Corona ''Scene envr settings'' enable ''Direct vis'' and add the Corona light mat and set the projection as ''frontal''.

I hope that helps.

Hi

I used the settings Beanzvision shown in this post

however, the aspect ratio is off with this- how to i resolve this?

Output resolution is set to the resolution/aspect ratio of the background image.

EDIT: I see you can edit the Scale and offset in the environment override settings, which is rather tedious, but then the aspect ratio of the shadow catcher is still off.




pls see attached file

Thanks!

I think you'll need to render this in the VFB not in the viewport, the viewport has a more or less arbitrary aspect ratio.
