When you choose a short update interval and a render node needs longer to calculate the Sec. Gi, the node will send its greenish "Light Cache Image" to the master which will bake it into the beauty... not sure if this is correct...

Looks kinda strange :)

Sorry, forgot to mention:

Hello,
when I render in Cinema 4D Particles, the error message "Scene bounding box is too large, some shading artifacts may occur" appears.
In addition, the artifacts mentioned are also produced.
Scene scaling etc. is fine.

This error occurs as soon as the first particles reach the end of their lifetime and "disappear". Does anyone know if there is a solution for this case?
The particle system is currently unusable :(

Within the Cinema materials there is a checkbox "Animated Preview" under the point "Editor" to show the animation of a texture sequence in the viewport.
Unfortunately I don't find such a checkbox in the corona materials. Am i missing something?

Would it be possible to add something like this?

Hello,

we are evaluating the Demo-Version of the C4D Plugin right now and it seems to be pretty unusable when using the Interactive Renderer :/

Its crashing all the time and i was able to narrow down a nearly reproducable bug.

1. put a Corona LightMaterial with an animated texture on an object
2. animate the objects position or rotation
3. scrobble or click a random position in the timeline while in Interactive Rendering
4. enjoy a crash

The possibility of a crash increased when using a animated texture, but we also had crashes just with a plain light material assigned.


Reproducable on two different PCs.

Bug appears with the Corona 3 Hotfix 1 and also with the Daily Build 2019-02-20.
Cinema Version is R20
Windows 7

Edit:
created a ticket. #17392

I need help / Sampling Focus, Lights
« on: 2018-10-25, 16:25:16 »
Hello, I have a little problem here.

It seems that the "Sampling Focus" is especially strong on and around light sources (e.g. front lights of the bike), while other noisy spots never become clean (area above the front lights, helmet reflections). I know there was an oversampling of dark areas in the past, but now it seems to behave the other way round in some scenarios.

Does it make sense to turn off the adaptivity in such a case?

I don't know why, but I have the feeling that the good old "bucket mode" used to do better on "DOF highlights" and other special cases than the "new" adaptivity mode.
It was said that it will never come back... so, are further improvements of the adaptivity algorithms planned for future releases? :)

Resolved bugs / Strange Artefacts with Sharpening
« on: 2018-01-31, 17:08:16 »
i just discovered a strange bug when using Sharpening/Blurring:

Framebuffer looks great but the saved EXRs show some strange horizontal and vertical artefacts when there is a bright light source...
if i disable Sharpening, everything works fine.

Edit: Corona 1.7 Hotfix 2

3ds Max 2016

Create a Free Camera
Enable DOF

Enable Auto-Key
Start IR (i used the IR in the Quad View)
Animate Target Distance
