OctaneRender® 1.025 b2.56 Test release [obsolete]

[PeterCGS]

There is a annoying incontinuity between how two different machines renders a frame. If I render out a animation with frame step two, and let two machines render odd and even frames, the animation I get in the end has alot of light intensity flickering. The machines are mixed between multi and single GPUs, so I guess this has something to do with it. It would be good to know why this happens though, because my plan of setting up a larger GPU renderfarm will not happen if this isnt fixed :O

Are you using the same camera and imager settings on both machines? Given the same settings Octane should render an image with the same brightness.

Emissions don't work for me in this release. I opened a scene created in 2.55b and none of the emitters work. Even if I re-create an emitting material in 2.56, still nothing.

Did anyone else (on Linux) experience such behavior?

We checked on Linux, and emitters work as expected. Do you have a scene you can send us which exhibits the problem?

Yes that what I hoped aswell. But after testing several scenes, I notice that it flickers for all scenes with large emitters like blackbodies etc..

[roeland]

I tested it here, and given the same settings Octane will render an image with the same brightness.

Does the flickering occur if you render all frames on one computer? (or does it occur if you make a movie with all even frames which are rendered on one computer?)

If you save you scene as an OCS file, and render this file on both computers, does it yield images with the same brightness? If not, is it possible to send us this scene, so we can see what the problem is?

Can we have this little improvement in the future release;

* the option to box select a group of nodes (which constitute one logical material) and save them together into an .ocm
* since they are selected, we could move them around together, not just one node at a time
* right click -> import nodes at cursor location (instead of global coordinates at which the nodes were saved into ocm)
* we would really need the option to save an .ocm without embedding textures. Saving 4k / 8k textures uncompressed is so damn wasteful without reason, and brings the problem of unacceptably long saving times for .ocs projects when you have imported nodes with embedded textures.

Yeah the node graph editor needs some attention. We will include some of these improvements in our next release.

Hi, I tested emitters on the preview ball and a new simple scene and they indeed work in 2.56. But when I open some project in 2.56 the emitters don't work. So I stripped that project scene down to only the emitting planes and tested it in both versions. The scene is attached below.

Hi Roeland. I will send you the scene files, and some tests. I got one machine with 2x480GTX, and one with 2x560 and one with 1x580. I render out frame 1,4,7,10 etc on computer nr one. Frame 2,5,8,11 on computer no 2. And 3,6,9,12 on computer number three. When rendering like this it flickers like crazy (the feeling is that it looks like a old projector). If I render out frame 1-4 on computer one and 5-9 on computer two etc, the problem is there, but not at all so visible because the illumination changes are minimal because it only happens when between frame 4/5. Anyway I will pm you with attachements! Thanks!

Hi, thanks for sending the test scene. We could find the problem, and we may do an update to 2.56 solving this.
