[C4D] Bug Reporting / XRefs Generator and IR
« on: 2024-04-16, 12:24:37 »

I'm using some XRefs in my scene and the following message pops up even when the XRefs aren't loaded (I only enable them for the final render).

Would it be possible to take the load state in account ? Or better, could the generator mode be supported in IR ?

Thanks !


The title is a bit long but really describe the issue :

Everytime I'm trying to enter a value between -1.0 and 0.0 the value is reset to 0. And it's not only visual since the value is really 0, confirmed it by dragging the setting to the console.

Has someone else encountered the same issue ?

C4D 2024.3.2 / Latest Corona 12 dailybuild / Win 10
(it was happening on 11H1 / 2024.2.0 too)


It seems that using the "Save selected objects as..." command located in Object Manager > File is saving materials incorrectly: in the saved scene their custom values are restored to the default ones. I've tested the command with two other render engines and it does not happen.

Can you confirm the issue ?


[C4D] Bug Reporting / Corona 11 VFB issues on macOS
« on: 2024-03-10, 20:00:22 »
Hi all,

I'm encountering a few issues on the macOS version of Corona, all related to the VFB. I'm using Corona 11h1 on Cinema 4D 2024.2.0 on macOS 14.2.1, with a Macbook Pro M1.

- I can't zoom in/out with the trackpad
- I can zoom out with the shortcut "Cmd -" but can't zoom in with the "Cmd +" shortcut.

- The horizontal scrolling direction is inverted compared to what is happening in macOS. The vertical scrolling direction is right though.

- I can't modify the text of the note under the stored images


Hi everyone,

I've added the support for our beloved render engine to Quixel Bridge.

Details are on my Gumroad page, let me know if you have questions but it should be pretty straightforward, it just works.

Quixel Bridge Importer for Corona Renderer (C4D) on Gumroad

Features in v0.3
- complete Megascans maps support including even metalness, translucency, transmission, fuzziness
- combo channel map support ( AO+Albedo, Normal + Bump )
- decals support, loaded as Corona Decal
- exact displacement scale, acquired from the asset's metadata
- new settings added for greater control over the material creation process and to improve displacement management

[Scatter] Cinema 4D - Bug Reporting / Vertex Map
« on: 2024-02-20, 15:11:31 »
Hey guys,

Not sure if it is something only on my side, but does the Vertex Map supposed to work in the Scatter Distribution channel ?



When IR is running, changing the Max Limit value in the Config tab is making instances disappearing from the rendered image.

EDIT 1: In fact it seems that altering any value during IR is making instances disappear ( tried with Count and Per Square values )

EDIT 2 : OK, I've found the culprit. This is happening only when the instanced objects are Corona Proxies. The thing is that I was using a preset from the Cosmos Library, so it's kind of the default behavior, not the best first impression. IR works fine when they're converted to regular mesh objects.

Hey guys,

New script !

Batch Load HDRIs
Simple but effective, it allows you to load several HDRI at once, with some control over the way its done.
It can be useful to quickly iterate during the look development and dust off that "HDRI" folder stuffed from the last Black Friday deals.

Files are attached, docs are here, demos below !

Enjoy !

Default Mode

With the select shader

It can load the files as Corona Light materials

Hey guys,

Here are some custom scripts for you, just in time for Christmas !

- C4D Bitmap to Corona Bitmap
- Corona Bitmap to C4D Bitmap
- Update normals filtering
- Sort Corona Materials by Type
- Select Corona Materials by Type

I wrote them a quite some time ago but with the perspective of releasing more scripts next year, I've improved them in many ways and while they're not perfect (details here), I hope they will be useful to some of you.

Read the docs

Convert Bitmaps Scripts

Pretty self explanatory, convert all the bitmaps shaders in the material in one way or another ( C4D Bitmap >< Corona Bitmap )

Update Normals Filtering

Change the normals filtering method to Roughness Modulation over the selected materials.
Note that Roughness modulation comes with some limitations, mainly when mixing Corona shaders with Cinema ones. More info here :

Sort Corona Materials by Type

Sort all Corona Materials in the scene by type using dedicated layers

Select Corona Materials by Type

Select all the Corona Materials of the chosen type

2024.01.17 : Original scripts updated, two new scripts

[C4D] Bug Reporting / Filter Shader and bump
« on: 2023-12-15, 11:59:26 »

Another one related to bump channel, I don't know if it has already been reported :

Doesn't work in IR and in final render.

Note that I'm using the Filter and not Corona Color Correct because the latter is missing few convenient settings ( gamma, brighness/lightness, working contrast )

EDIT : Colorizer doesn't work too. Will the bump channel will be fixed one day ?

[C4D] Bug Reporting / Corona Tile Map - Gap bump
« on: 2023-12-15, 11:14:29 »

I can't get a bump effect on the gaps with the Corona Tile Map, in IR and final render. Is it supported ?

[C4D] Bug Reporting / Anisotropy orientation UVW override
« on: 2023-12-04, 11:06:56 »
Hello again,

Just checked on the v11, the UVW channel override for anisotropy orientation also isn't working, I don't know if it was already been reported.

Hi guys,

Sorry if that was already asked but I haven't found any topic regarding this subject. Would it be possible to have a setting to choose the type of the bitmap shader created when performing a dragndrop in the Node Editor ?

Something like this :



The new "adjust resolution to VFB" feature is cool but often I need to use IR in full res to check textures fidelity in the final resolution. In this scenario it would be handy to have access to this setting directly in the VFB, with the VFB reacting to it on the fly (without the need to stop / restart the render).

In general it would be nice for the VFB to adapt instantly to resolution / format changes from the render settings, like in some other render engines.

Hi, the title pretty much says it all. It may sounds niche but in retail I use extensively .ies light in Cloner to reproduce spot lighting, and I found this bug.

- Create a Corona Light
- Enable ies and use one .ies file from the Asset Browser
- Parent the light to a Cloner
- Start IR = works
- Start a production render = Corona get stuck at "Preparing Scene Data" forever, using between 30 and 60% of CPU.

Its only Corona which get stuck, C4D is still working in this scenario although I can't closing because it is waiting for Corona to stop the rendering process.

Note that unfortunately making the Cloner editable and get individual instances doesn't change anything, BUT changing the path to the .ies for something absolute is working ( copying the .ies somewhere on the disk and using the filepath ).
