Gallery / AXIS Kitchen

« on: 2016-05-05, 15:29:45 »

Hi all, this is my very first post in the Corona gallery. As many things happened the last 6 months, I had no time to post some images I created while I was working and representing Delta Tracing in the past. Since September 2015 I moved from Nvidia iray to Corona and these images are my first attempt which I produced a month later, October 2015. I have others too which I will post in the near future.

Final resolution was 5.500px and the rendering time was about 3 hours with 3 hexacore PCs used via DR.

Thanks,

[Max] Resolved Bugs / DR Servers - Initial Pass

« on: 2016-05-03, 11:27:29 »

Hi guys, is about a week now I am seeing a strange behaviour with DR.

When I sent a job with Backburner to a Master PC which then has to use DR with another server, the server task always shows Rendering Initial Pass and not the effective passes is calculating, if it really does. How is possibile after 3hrs and 49mins we are still in the Initial Pass process? Is this ok or something is wring with DR?

I attach an image to show you what's going on...

Thanks in advance.

[Max] General Discussion / Resolution for GEAR VR

« on: 2016-05-02, 17:02:20 »

Hi guys, a simple question here, what's should be the final resolution to render the Spherical images to use in Gear VR? I guess 4096x4096 is the minimum but for a real great experience and clarity what do you suggest? I don't want to render a 12000x12000 for nothing.... -.-

I search the forum but didn't found an official info about it.

Thanks in advance,

[Max] Resolved Bugs / Hi Res images and strange DR behaviour

« on: 2016-03-22, 12:50:41 »

Hi guys, I am using the final daily build 13/02/2016 and every time I use Backburner & DR with high resolution images (over 5.000px) I notice some issues.

Here what happens:

- The scene (around 10.000.000 polys and rendered at 6.000px) is sent to a server here in the office via Backburner and DR turned on.
- The server starts to loading the scene and do all the necessary tasks.

And here start some strange problems:

- The main server starts the rendering process and the initial pass I think takes too long.
- In the meantime, the DR server starts the process too and even there, the initial pass is a bit long to be processed.
- When the passes finally start to go on, the DR server seems always to be stuck at the 2nd pass. The rendering process bar goes on and when it finishes the second pass, instead of going to the next one, the information shows to start the second all over again.
- The main machine seems to go on with all the passes without any issues. Only the DR one has a strange behavior.

Here is the log:

What do you think, is this a bug???

[Max] Resolved Bugs / DR doesn't work - Build 06/03/16

« on: 2016-03-07, 11:49:45 »

Hi all!

Is it me doing anything wrong or there is a problem with DR and the latest 06/03/16 build?

So this is what happens:

When I start rendering with my main workstation everything seems going fine and the first passes are calculated. Once the DR server machines start to work, my VFB deletes automatically the image calculated at that point, and seems to start all over again. At that point when the DR image information arrive to the main workstation the final result seems always the same! At the end, the image is grainy and I guess the DR doesn't work perfectly. There is a kind of bad synchronization of the passes I think.

Actually, the same image calculated with my workstation is way better and cleaner than the DR one.

Can you confirm this?

Thanks in advance,

[Max] General Discussion / Albedo - Proposal?

« on: 2016-02-26, 09:40:45 »

Hi all,

I used till last September Nvidia iray in my professional workflow and I decided to start using Corona and personally I am very excited and happy with the results! Is a very powerful engine! Something I really miss and I bet all of you too, is a simple tool where we can set the correct Albedo values to our RGB colors and textures. Back in the iray beta testing cycle, I asked at the dev team to add the Reflectance Values & Transmittance Values which you can find in the material editor to their shaders too and they made it and it always worked out!

So, why we can't do the same for Corona? Those values are extremely useful and they work with both RGB colors and texture maps. Also I remember the iray team told me that the Reflectance values was calculating also the Reflection values as well!

What do you think?

Thanks in advance,

Dionysios -
