Frosted Glass and Reflection on Floor

[martinfdc]

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...

Can you screen capture your frosted material settings?

Here are my frosted glass settings:

Have you tried re-creating the floor material as a corona material? ie: copy and paste the settings from one to another. What is the cinema floor material by the way?

[martinfdc]

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


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

Give it a try I reckon, it should be easy to switch over. I'm guessing it's the floor mat that isn't playing nice. Process of illumination ;)

[martinfdc]

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

[Beanzvision]

Great!

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.

Edit: I'll try not to be too much of an ass.

Of course, the problem was created by the C4D material.
Corona is very easy to use, so it shouldn't be THAT hard to paste two maps and a color into the Corona material.

And it took two hours to solve the issue.

And No! Mixing materials from different renderers is never a good idea unless it's used in post.
When you use Corona, you use Corona's materials. Arnold, Arnold' materials. Octane, Octane's materials. ETC.

Engines work differently and the shaders are meant to be used with their corresponding engines.

I'd really like to say something positive but by the heavens...how did you develop the idea that mixing two different things wouldn't result in some problem or another.

In this case it should not matter if the floor material is Corona or Cinema material. We convert the C4D materials to Corona format internally anyway. The idea is that as a newcomer to Corona, you should not be forced to use Corona materials if you don't want to. Actually, supporting native materials and native and external shaders is one of Corona for C4D's features.

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.

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

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!

That's my material! lol Thanks for using it! :)
