[C4D] Bug Reporting / Loop Crash during Interacive

« on: 2022-05-23, 11:27:16 »

Hello, Corona user since the first release.
I'm experience for the first time a loop crash in this scene: https://we.tl/t-9KRR45W3Ij

iMac latest OS with R25 with Corona 8 (tried on a MacBook Pro as well)

When I start the interactive rendering or simple view render corona crashes...If I restart Cinema4D...sometimes stop to crash but after some actions I got a crash anyway...
This scene come from an Old Corona Render (maybe 6) but I tried to clear all settings, component and converting material...nothing works...
Thanks, the Apple Dump file has been attached...

[C4D] General Discussion / Reflections in Physical material

« on: 2021-09-21, 18:07:36 »

Hello all, name's Alex
I using Corona since V4. Now I'm play with v7 Physical Material system, I've a question:
How can I dim the reflections on a GLASS Mat as previously materials?.
With previously GLASS Mat (legacy) when I turn the Refractions and reflections on I can dim the reflection layer by using the IOR....now all has been "merged" on a unique IOR parameter.

E.g. I create a GLASS Box on a bathroom, and I see that the reflections are to much...now with only one IOR is very hard...
Thanks for any tips!

[C4D] General Discussion / C4D Picture Viewer slowdown C4D with Corona

« on: 2021-05-06, 11:31:49 »

Hello, I noticed a strange behaviour with Cinema R23+S24 and Corona 6 hotfix2 + BigSur. No problem with Catalina that I used until now.
if I start an high resolution render (around 4000 pixel picture) to the Cinema4D Picture Viewer and leave the window on Cinema4D foreground, all Cinema4D become unresponsive with a two or three seconds LAG. If I close the window (without stop the rendering) all become responsive.
Seems that the Picture Viewer with Corona Render make the whole C4D totally unresponsive.
This behaviour was not into Catalina system but only with BigSure (clean installation).

I have this issue to all my Office Mac with BigSur (two iMacs 2020, Macbook 2016 and Macbook 2018)
Anyone got this issue?

[C4D] General Discussion / Standard Stereoscopic Camera

« on: 2019-10-17, 09:28:59 »

Hi Guys, I noticed that Corona can handle stereoscopic render into the TAG settings of the corona camera. But seems it can be set only for special camera as spherical or cylindrical or cubic.
I would like how to set a standard stereoscopic with corona...but I think is impossible :(
I need to render a simple video but I don't want to make a 360 panoramic stereo movie, I need only a simple stereoscopic...
any tips?

[Max] General Discussion / Corona Activation under Proxy

« on: 2019-09-10, 11:52:57 »

Hi Guys, during next October I will teach on a school where Corona Render will be used as main render engine with Cinema4D. Last Year I was on the same school where a Proxy server gave me some activation problem for Corona Demo. All school computers are behind a proxy.
The school  IT man told me that I can give to him some internet addresses for better web surfing or something else.
How I can give to him the activation server address to avoid Corona staking on every cinema4D session? Where I can get the real address?

[C4D] General Discussion / Corona and same name materials

« on: 2018-06-01, 09:07:07 »

Maybe you noticed that Corona (and not only Corona) doesn't recognize if in your scene you have some materials with the same name. If you paste in the scene some object with same name material (es: mat mat mat mat mat) when you paste it in other new scene with mat mat mat mat, it issue drive you crazy.
To avoid it, our software developer from c4dzone.com, created a simple script that check if you have same name materials and append a number. So before paste object in the scene, give to all mat the same name (es: boing) and the plugin give to all materials boing_01 boing_02 and paste object on your scene without problems. (you must move manually your texture to the target scene as well)

Hello guys, I’m try to test on a render farm (not mine) the corona render on c4d.
All is fine but some machines doesn’t render denoised image and the result is different on some frames.
The farm replay to me that all machine are the same.

[C4D] General Discussion / Corona on different processors

« on: 2018-05-23, 17:45:11 »

Hello, I'm Alex...
I'm using corona (lates beta available) on two different machines:

1) iMac with intel i5 quad core
2) MacBook Pro i7 quad core

The iMac and the macbook have the same "cinebench", around 700 render points so when I use other rendering engine it takes the same render time. I noticed only a couple of minutes of different render times. I assuming that the processor calculate in the same way.

On corona I got big different render times.

The MacBook seems to be three time quickly of iMac. :-O
How is it possible if both machine have identical Cinebench???

thanks!!!
Alex
