Octane preview window stalls. Tweet

[asher]

I have this issue, the Octane preview window stalls upon trying to finalize a render and save via the LW saving formats. ( i have reported this before, but it has come back )

However:

1.- Octane preview window still can save via "preview image" correctly. but only manually. Say 8bit PNG.
2.- It behaves as it everything stops at arround 97% or so ( with ALL projects ), but is NOT a CRASH, as if i click abort+cont, the next frame renders, and then stops again at 90 something percent. ( frame is actually finished, but no green bar appears as the Octane plug attempts to save frame though LW, but never does )

3.- On an animation at say 4K, it will render say 5 frames OK, then it may stall at frame 6 or so. CPU, RAM and GPU ram all ok. GPUS stop working because the frame is actually finished, the issue is that LW or Octane plug, has trouble saving the LW file format ( tiff24, or any other one )

I suspect there is a bug with LW or Octane for LW were the buffer that attempt to save though the global LW settings is halted. I monitored RAM, plenty left on both System ram, and GPU ram.

Secondly, another huge issue is that on SOME projects, not all, the png saved from the Octane preview window is perfect, just like the preview shown on screen while working.
BUT, when the frame is finished, and the image is saved though LW global settings, ( say tif 24, tif 32, etc ) everything goes to hell, gamma, exposure, saturation, very, very different. Unusable.
LW is set to LINEAR colour space, any other settings that i may have missing? I bet i am not doing something right.... I just want a tif file that looks exactly as the preview window. I would not mind PNG, but i have to manually monitor and save before frame finishes!

Request: the Octane render status window does the job well ( regardless if there is preview turned on or not ) ......can future version of the plug save AUTOMATICALLY? ( bypasing LW )
AND saving in regular sets of time? say: save at 25% completion, then 50% completion, etc.

Thank you.

Hi,

Regarding your first problem, you should update your plugin to the latest 3.07.0.1 build, or at least to the 3.06.4.1 version. In this version, there is a bug fixed probably related to your preview window freeze problems.

About your second problem, if you have issues saving the images from LightWave (using the LightWave save functions), why don't you save the images directly from Octane enabling the render passes node options? Even if you only need the beauty pass, you can save the images from the render passes node. These files are saved directly from Octane, and should match any preview that you get in LightWave (if all the LW color space functions are disabled)

Thanks,

HI Juanjo,

I am still experiencing this problem after many months. I have the versions you recomend above.

How can i actually bypass F10 render from LW?

I have the render passes on, it saves ok, but since the only way i know to render in LW is via f10, if F10 window halts, so does the render passes as well.

Please help!

Thank you.

Hi,

Have you tried the latest plugin build available, 3.08.2.0, or the new 4.00 RC5 builds?
viewtopic.php?f=36&t=68207
viewtopic.php?f=36&t=68879

I remember a problem like that, but I supposed that it was fixed, because I have not any recent report about it.

Thanks,

I am using 3.07.0.1 build

will try the new 3.08

Any way of bypassing F10 rendering?

[juanjgon]

Hmm, nope. How are going to render the scene without starting the rendering with F10? What you have is an option in the plugin options panel to disable the image preview, leaving only a small window with the rendering statistics, but I don't think that your problem could be related to the preview window.

If this problem is not fixed while working with the 3.08.2.0 plugin build, please let me know to further investigate.

Thanks,

OH Juanjo, no ofline licensing on 3.08 ??? this is unusable!
I see version 4, also people complaining about animations stopping, no ofline licensing??

So 3.07 is the last usable version and has this major bug!

reporting 3.08 also halts randomly
