OctaneRender 2022.1 for Houdini production build 2022.1.1.0

[Midphase]

Sorry to double post, but my IPR in Houdini is not displaying any image.

I'm running on a Mac Pro with OS12.6.3 on an AMD 6900XT GPU.

In Houdini, I can't get any image to appear in the IPR, and I'm sure it's user error but I was wondering if anyone had a clue as to what I'm doing wrong?

I have followed the instructions in the manual for the basic scene, created a ROP in the OUT context, created a Render Target in the MAT context with a couple of Octane Materials and assigned the materials.

I hit IPR and I feel like I should be seeing something, but it's completely black.

Thanks for any help you guys can provide.

PS

FWIW - the Octane standalone works fine, so I know it's not something with the GPU or my machine.

So it's pretty weird, I didn't manage to narrow down to a specific issue. The first time I opened up Houdini and submitted a sequence render, got a crash after 4 frames. Opened up again, same scene, same settings and manually stopped the render at 60 frames - all went fine, no crash.

Not sure what might cause the issue, will investigate with a few other scenes, will keep you posted Juanjo.

Yeah, this is the main problem. This crash has been there for a long time, it is a core issue while cleaning the scene. I've tried to fix it on the plugin side several times but without any luck so far. With this latest plugin build I can render thousands of frames without getting the crash, but sometimes the scene cleaning functions crash after rendering only a few frames. It is something really hard to reproduce.

Check if you have a DisplayName/ViewName selected in the RenderTarget node - should be on the Imager tab.

Yes, you can have a problem with your OCIO color config.

Here's what it looks like in the settings you mentioned. Doesn't look like OCIO is enabled, or anything for that matter:

Hmmm...okay. Are you using a Daylight or Texture Environment to light the scene? Main tab on the RenderTarget --> Environment

Hi, I had several issues in the pass with the OCIO settings, I can see in your image that under the OCIO settings, the ocioDisplayName and ocioViewName the selector values both are in bold despite not having different values from the default ones. I couldn't export images before because of this. Try resetting these two values so they don't show in bold (ctrl + middle mouse), this solved my problem. I hope this helps.

Perspective correction in universal camera doesn't do anything.

Hmm, how this option works in Standalone? From the tooltip, it works if the camera up vector is vertical.

-Juanjo

Sorry for my ignorance, but how do I change the camera up vector in Houdini?

I believe the up vector is set to Y axis by default. If you want to play around with it, you'll have to enable a few hidden parameters on the camera parameter interface.

Hey Juanjo,

still have random crashes when rendering larger scenes, tried using command line for the latest and managed to get some sort of crash report from Windows. I'm not sure if it helps, but this is what I got (nvidia 531.61):
