[C4D] General Discussion / Corona Sun Open GL Preview
« on: 2018-04-05, 17:26:38 »
Hi,

I have a Corona sun and I would like to preview the shadows it produces in Open GL.

Firing the interactive renderer is not an option because the parsing stage takes too long (I'm working on a large and complex file)

Can anybody tell me how can I preview the Corona sun's shadows in Open GL... or maybe how to recreate the shadows a Corona sun would produce with a Cinema 4D light.

Thanks in advance.

What does one need to do in order to enable shadows (of a Corona Light) in Cinema 4d's Viewport when having Enhanced OpenGL activated?

I manage to do it with a C4D Light but not with a Corona Light.

As you can see in my two screenshots, one has a Corona light and the other C4D Light... I can't manage to turn on a preview of the shadows the Corona will produce in C4D's viewport with Enhanced OpenGL.

Is it possible to preview the shadow of a Corona Light in the viewport?

A hand would be much appreciated!

Hi,

I'm not familiar with the takes system at all I'm afraid. But just thinking out aloud, can you tell it to save your renders as OpenEXR's? That should at least allow you to load the image/s back into the Corona Image Editor for further tweaking.

Beanzvision, I can save Exrs but then I can't play with Lightmix. For that I need a cxr. But due read further down, my answer to TomG.

Now, I have never tested this with the Takes system, so don't know if it would work, but there is the "Auto save to VFB history on render end" in Corona -> Preferences (see attached)

One word of warning would be that I am not sure what effect this has on memory, if saving the images and having them in the history would require a significant amount of memory or not, especially as there would be LightSelect passes etc saved each time.

TomG, your solution worked just fine. Many thanks. It doesn't have any negative effect on the memory as the images are stored in the hard disk, in the preferences folder of C4D under Corona>History. There one finds all the cxrs and can they tweak all of the renders each one with it's specific lightmix. Crazy awesome!

One thing worthwhile noting is that if one saves from the VFB, one only gets the cxr of the last rendered image. Even thought you are clicking on saving an older render than the last one... Anyhow, this problem can be bypassed by accessing the preferences folder where you will find all of the history of your renders in cxr format (having you enabled "Auto save to VFB history on render end" in Corona -> Preferences)

So many thanks for your help. Now I can work on all of the cxrs of my rendered history.

Hi all,

I'm using Cinema 4d's Take system in order to batch render many images.

On Cinema 4d's Picture Viewer I'm able to see all of my rendered images but in Corona's VFB I only see the last rendered image.

Is there a way to tell Corona to save all of the images rendered in the History of Corona's VFB?

I would like to leave my computer rendering all night and come the next day to play with my LighMix, not only of the last rendered image but with all of them.

I know I can save or export my images from Cinema's picture viewer but in the picture viewer I can't play with LightMix...

Is there a way to make this happen or am I just asking nonsense?

Many thanks. Clearer than water.

How does one do to render only selected objects?

Beginner in Cinema 4d and in Corona...

Maybe I sound a bit of an ass when I say "Glad the issue is fixed. Maybe it might be worth while making Cinema 4D materials also compatible in this type of circumstance."

I'm by no means complaining that Corona doesn't have this compatibility. Corona totally rocks and I'm glad it's already in Cinema 4d!

I was just kind of wishing that this compatibility could be addressed in some future release. But you're totally right Eddoron, copying two shaders ain't no big problem at all!

Eddoron, the material the frosted glass has is from the page you have linked in your signature: https://www.corona-materials.de/en

This is the specific material I used: https://www.corona-materials.de/en/material-library/glass/frosted-glass/123

If you're the owner of that website I thank you very much for starting such a great site.

Eddoron, it was never my idea to mix two non Corona materials. The mixing of two materials came about due to my workflow.

I’m working on (with my fellow workmates at the architecture firm I work on) a large housing project (with hundreds of materials) on Vectorworks (BIM software) and then directly from Vectorworks exporting to Cinema 4d. This workflow works great and is the fastest way to get my model to Corona renderer.

The material of the glass door was normal glass (texture placed in Vectorworks and then automatically converted to a C4d material during the export process) then it was decided that the glass was going to be frosted. So I created the new frosted glass with a Corona Material.

Then the problem occurred with the floor and of course I immediately knew it was due to the fact that the floor was not a Corona material. Anyway I wanted to share this information with the developers as it is in their interest to make any kind of workflow faster and easier.

If I would be creating the scene from scratch in Cinema 4d, of course, I wouldn’t be mixing materials from two renderers. The mixing of materials is due to the fact that I’m exporting from another software into Cinema 4d and only when a problem occurs, I change the material that is having issues to a Corona material.

So until there is no scene converter from C4d to Corona, this will be my method of working. 

Sharing this kind of problems helps the developers of Corona on developing the scene converter or any other thing they’re developing.

The problem was produced indeed because of the Cinema 4D material.

Here I post the image with the floor texture as a Corona Material and the reflection is now a correct one.

Glad the issue is fixed. Maybe it might be worth while making Cinema 4D materials also compatible in this type of circumstance.


56
Many thanks for your prompt reply. I shall change the material to corona and inform the results.

57
I haven't tried recreating the floor material as a corona material yet...


Here is the floor material as configured in C4D material...

58
Here are my frosted glass settings:

59
I guess this problem is occurring due to the fact that my floor has a Cinema 4d material and the frosted glass on the door is a corona material...

The reflection from the outside of the door is being reflected on the floor..instead it should be reflecting the frosted glass.

I will render again to see if this is the problem. I hope it gets solved..

Bu is it's a problem it would be nice that one could use a Cinema 4d material combined with a Corona material in this case...

Many thanks Eddoron. I found the setting.
