Hello Everyone,

I recently purchased a new workstation with an  AMD Ryzen Threadripper 3970X CPU.

In the task manager it's indicating only 85% CPU is being utilised but when I look at HWMonitor it says 100% whilst rendering. I'm just a little confused to why that is and what is the actual utilisation?

Any help would be appreciated!

Here are the rest of the specs of the workstation

-AMD Ryzen Threadripper 3970X  32x 3.7GHz
-MSI Creator TRX40 | AMD TRX40, E-ATX
-128GB Corsair Vengeance LPX DDR4-3000
-NVIDIA GeForce RTX 2080 Ti 11GB ASUS Strix OC
-Corsair H115i RGB Platinum + 2x LL140 RGB 280mm
-6x 120mm Corsair Light Loop LL120 RGB
-Windows 10 Pro 64bit

Hi all,
I have been recently having an issue where I suddenly get really long calculation times for computing secondary gi since updating to corona 4. I actually had this issue some time ago when I switched from corona 2 to 3 but never really found a solution.

My scene was only needing seconds to calculate secondary gi but suddenly it's estimates an hour(i quit after 10 mins). If I restart my computer and render at a lower resolution it eventually works, but I have to restart my computer every time I change the camera and can't render at 3000 pixels or above.

I thought that this is a RAM issue but I'm not getting any RAM warnings. Also I tried it on a scene that was working before installing corona 4 and the scene just stops rendering after about 30 passes with cpu usage going down to like 5%.

I also tried checking the conserve memory box to no avail. Also I have a back up system(crashplan) running at the same time, could this interfere at all?

Has anybody else experienced this kind of issue? I would appreciate any help. Cheers!

Here is a personal project titled “Pumpkin Harvest” that was my entry to the CGMood autumn competition.

I was inspired by still life photography by both Ustina Green and Anatoly Che.

Nearly everything in the scene is photoscanned using Agisoft Photoscan.

I need help / Long computing secondary Gi times
« on: 2019-01-09, 11:52:32 »
I have been having an issue since installing corona 3 with long calculation times for computing secondary gi. I switched in the middle of a project from corona 2 to 3, the scene was rendering fine in 2(like 30 secs to calculate secondary Gi) but now it often estimates over an hour.

-This problem is not scene dependent as it has occurred on two scenes now. These scenes have a number of high-res textures(8k) but I know its not a RAM problem as I am using only half of my RAM(64GB) on each scene.
-If I restart my computer and start a render it calculates in seconds. If I work on the scene and try to re-render then the issue occurs.
-If override the scene with a clay material also no problem.
-The problem seems to mainly occur at rendering higher resolutions like 3500-6000.

I have the newest NVIDIA drives installed for my machine.

Here is my machine specs:
Intel Core i7-5820K, 6x 3.30GHz, NVIDIA GeForce GTX 980 Ti 6GB , 64G RAM, Windows 8.1

I would appreciate any help, as I am not sure where to get started on fixing this issue. Cheers.

I am fully aware that christmas is long gone but here is a project I meant to get finished last year with some swiss related christmas food. I created all the food assets using agisoft photoscan, cleaned up the models with zbrush and rendered with corona 1.7 putting the new sss shader settings to good use.

If your interested in the food products, I have made them available here.

Full res images here.

C&C welcome!

Hello everyone

I have been seeing the string shelf system being present in a lot of interior images lately and decided to do a small personal project featuring it.
Rendered with corona 1.6 and post production with Arionfx.

Hello everyone,

I have been working on some 3d assets using photogrammetry. You can download a bread for free here:

Hope you like it and can use it in your scenes! Below some other assets I created.

Hello everyone

I would like to share a personal project "White Haze" rendered with Corona 1.5.
The aim of the project was to create a simple apartment and model the majority of the assets within.

I used Agisoft Photoscan to create some of these assets.

I hope to add some more images to this set in the future.

C&C welcome

Hello all,

Here is a personal project of mine where I decided to create some “still life” images based on some Swiss foods. I used photogrammetry to create the models in Agisoft and Corona to render the images.

C&C welcome!

Hi everyone,
I would like to share my first project with corona:) This is a personal project, based on an existing house in Japan called "Slit House" by Eastern Design Office architects.
Software used was 3ds Max, Corona 1.2, Groxfx, Arionfx and Photoshop.
