OTOY Forums

nice renders roubal, but there is aliasing, have you tried the trick i describe in the resources forum ? (rendering good images for our competition)

Radiance

Hmmm, I have not seen this topic... I'm going to. Thanks !

Edit : well, topic read. I use this method in Blender for my videos when frames are not too long to render.

On my current scene, I can't add a single triangle or a texture without crashing, and it's a miracle if I can render this scene. I haven't exited from octane for 2 days because I have the fear of getting a corrupted ocs and having to setup the scene from scratch one more time, so I'm not confident in attempting to render at 2x the current resolution.

Octane is currently rendering an image. I will try if it shuts down by accident, not before !

why should you get corrupted OCS files ?
just save a copy, restart, load the copy, up the resolution and click on the node.
if you have enough memory it will work fine.
if you run out of memory, just open your ocs again?

I'm not sure that ocs files are really corrupted, but when I load an ocs, I have discovered after many deceptive attempts that I have to take strong cares after loading the ocs : I must wait several seconds before I can click on the Mesh node, and I must click only one time, otherwize I get a white screen , a freeze with window displaying in the low bar that Octane doesn't respond, and finally a file loaded without any texture and materials messed up.

After clicking on the mesh node, I have to wait maybe 5 minutes without touching anything before having my scene loaded, and even with so much care, it doesn't work each time.

So, when a scene is loaded, I render as many images I can !

After rendering the image below, I decided to do a trial with your method, with resolution set to 2048x1152 instead of 1024x576. The last proof screen shows what I got. Sadly, but as expected, as soon as I moved the mouse, Octane has been closed.

I attempted to reload the ocs 3 times with the same result. I must say that the numerous fireflies are moving on the screen at high speed, like noise (snow) on a TV set.

Opening Blender, I notice that the same fireflies were dancing on the screen. Something has probably been corrupted in Open GL. After rebooting the computer, the fireflies disappeared.
After reading an advice in a post, I have installed EVGA precision, to see the temperature of my GPU : 74°C when rendering (62° when idle).

You can notice that textures are moved to weird places : the license plate is inside the door, from outside, the wood texture of the dashboard is mapped on the sides of the tires, and I don't know where the red color of the dashboard comes from. All the textures of the surrounding are lost.

So, I can't reload my scene. I think that Octane accepts textures added one by one when the original scene works, but that loading everything in one time is too much for my GPU or memory.

On this new image, I got many fireflies on the top of the steering wheel, and they have been hard to kill with the one pixel clone pencil.

ok this one new entry for the contest is my camaro
render time aprox 50 min with 250gts
for look the scene shot and progress check the section work and progress.
thx.

Hi,
This is my project for competition. Its waterfall. Model has 1 698 727 triangles. I make direct light via Hdri. I don`t use Octan direct light (opacity is not supported).
I use my GTX 260 and rendertime is circa 30 min.
I include picture from testing water in octane. My base inspiration is this photo

Other scene for this competition
Classic coast. Scene has 1270371 triangles. Renderd in octan. I include these images from modeling etc
Rended on GTX 260 - circa 20 Mins.
In picture 01 is sample of stones in coast

Very nice lukashanak.eu. What did you use for creating waterfall?

Cheers,
n1k

Wow, Great images Lukashanak ! My prefered is the waterfall. It looks more natural.

I have got a question : How many objects in you scene ? Did you use few huge textures ?

I ask that because your mesh node has only 8 input. My own mesh node for my car scene is larger than the screen and I can't even count how many input it has !
