Release Notes
=============================================
RELEASE 2023.1.0.0 (Current stable)
=============================================
* PLUGIN FEATURES AND FIXES:
- Added support for saving images in TIFF and JPEG formats
- Added "Postfx Media" Auxiliary AOV
- Added curvature visibility object layer parameter
- Use extension patterns for file selection windows in the plugin nodes

Reworked how the plugin handles tonemapping/colorspaces:
- Added "Default for file type (sRGB/linear sRGB)" color space setting in the ROP which will use linear sRGB for EXR and sRGB for other formats. It's the default option now.
- IPRs now don't get any tonemapping settings from the ROP, instead they use imager settings
- Saving images from IPR now use correct colorspace (srgb or linear srgb depending on file format) instead of getting colorspace from the ROP. This way the saved file looks the same as in the IPR. We are considering adding an image save window similar to the standalone.
- Added "MPlay Use sRGB color space" setting in the ROP which is on by default. Disabling it would switch MPlay color space to linear.
- When "MPlay Use sRGB color space" and "MPlay bake color correction" is enabled, MPlay preview now should look the same as the actual image file saved from the ROP.
- Removed MPlay gamma setting from the ROP.
- Unified the way how plugin obtains tonemapping settings for the ROP to remove inconsistency. This should fix some tonemapping issues.

- QT5 IPR is now the default one on all platforms
- Changed default value of ROP's image file name and added hint for it ($HIP/render/$HIPNAME.$OS.$F4.$OCTANE_PASS). Previously it didn't include $OCTANE_PASS which would output all the passes into the same file name.
- Display error message if multiple passes were saved in the same file (after the rendering from the ROP is complete).
- Sliders for postprocess changed to logarithmic
- Fixed bug when "Beauty" pass couldn't be selected in the AOV menu when "Show denoised" was enabled.
- Fixed upsampling not working in IPR
- Fixed potential crash on linux in render target python code
- Renamed nodes Projection linear => Projection XYZ to UVW, Projection UVW => Projection Mesh UV
- Updated facebook group link


=============================================
RELEASE 2023.1.4.0 (Beta 4 SDK)
=============================================
* PLUGIN FEATURES AND FIXES:
- Added new "instances IDs from" option: "point number". It will use index of a point and will work without having to manually add any attributes. Also it's now a default option.
- Directional and Analytic Lights feature is added in the Octane Spectron node
- When opening scenes saved in previous plugin versions, now version conversion will be executed. It is required to ensure that new properties added on the existing nodes and that the scene render visually looks the same as the old version. It will show a prompt asking what exactly to convert so it can be skipped in case there is a bug in the conversion.
- Added post processing lens and volume effects
- Light IDs and Light Pass count increased to 20
- Added new composite texture layers
- Default Spectron Light changed to be Quad
- Save orbx and image dialogs now use corresponding extension mask (e.g. *.orbx or *.png)
- Save orbx and image dialogs now have pre-populated file name in the dialog, e.g. mySceneName.orbx
- When overriding existing file, confirmation dialog is shown
- OCIO view/look in the render target imager changed to be more like in standalone - one dropdown for view and one for look. Added previously missing ability to select "None". If a view/look is missing (e.g. another config is loaded), the label should appear with a "missing" message.
- Toon material and Toon Ramp nodes are moved to the Materials section
- If plugin is loaded in Houdini version with unsupported ABI version, an error message will be shown. It means it's now easier to check if a new Houdini version is compatible with the plugin - just run it and if there is no error messages, it should be good.
- Fixed Spectron Spotlight "Throw Distance" freeze/crash.
- Fixed Saving the render from the QT Render Window gives errors. (No OCIO configured)
- Fixed the wrong default value for OCIO view/look
- Missing OCIO view/look now should render with no view/look instead of triggering OctaneRender error
- Fixed compatibility mode behaviour for nodes that didn't have compatibility mode in previous version
- Fixed composite texture connections bug (disconnecting of reverse-ordered pins)
- Fixed Adding Adjustment Layers (Math Binary) or (Saturation HSL) freezes Houdini
- Fixed Packed Geo Instancing on Object does not use AOV / Render Layers correctly
- Fixed incorrect behaviour in Gradient nodes
- Fixed scatter on mesh node that wasn't working correctly
- Fixed bugs in loading of some LocalDB shaders
- Removed underscores from octane light digital asset names
- Removed "composite output AOV on gpu" setting
- Only one imaging gpu can now be selected in the settings. Imaging GPU is always enabled for rendering.

Common Issues and Solutions
- If the plugin doesn't work at all, set HOUDINI_DSO_ERROR = 2 in houdini.env and check for messages in the terminal.
- If you're missing libglut.so.3, install the freeglut package.

Happy rendering,
Your OTOY Team

Hi!

Thanks for the new release.

Upgraded today. The Windows machines are happy.

All linux boxes crash on image saving with the following log. Not sure if there's clues here or we need to diagnose ?

EXR is our output format; the scene is the same as we've been trying to render recently (on the Betas) so this looks like a new issue on the Linux 19.5.773 build ?

Renbry
Thank you for reporting!
Could you please DM me the command line how you run Houdini?
The call stack helps, I have an idea why it may happen.
There was a change in how ROP image format work, there is a chance that you'll have to manually set the image format in your file again. Can you please open you file, go to the ROP -> Output and make sure your output format is set to EXR? Just set it to EXR again, save the file and try rendering please.
Another problem here is failed assertion crashing the app, which should not happen in release build.
Sorry for the inconvenience, I'll look into better testing of linux builds.

[Renbry]

In fact, you're right. I just checked the output format and the EXR files were set to PNG format. Funny that Windows was fine but now the Linux + Windows machines are happy = I'm happy!

Better, is that I can do batch-frame rendering now to get a LOT more speed out of the rendering.

I'll report in if anything new pops up but this seems great right now!

[lavrenovlad]

Thanks for the update! Finally some real work is done on the plug-in.
I wanted to mention existing bugs:
1. When there are a few ROPs in a scene and you just opened a HIP, choosing one of the ROPs in the IPR ROP menu leads to an error.
I usually just start the IPR with the "play" button it launches the first ROP in the list and then I switch without errors between them.
2. Sometimes there is an "out of memory" error when using Region Tool, from my experience it happens in any sort of heavy scenes and when I use the zoom feature in the IPR.
So basically if I zoom in with the scroll wheel in IPR and after that I use region tool I get this error. It's pretty general issue, I have it in every project.
3. There is an issue with lights, basically render flag affects if they are visible in render or not which is wrong.
Sometimes I wanna turn off some lights so the viewport is cleaner, but I don't want to turn them off in Octane as well.
4. Also sometimes when I wanna move/rotate lights with Octane IPR on, the IPR and Houdini in general stops like it's reloading something even though there is no need to.
Especially happens in scenes with instances. I need to turn off most of the scene objects that cause the reload so I just can move and rotate the lights in real time here and there.
5. And entering MAT context while IPR is on makes it reload too. Is it supposed to be like this?
Let me know, thanks!

[lavrenovlad]

Weird that Position pass doesn't work in my existing project anymore, it worked in the previous beta.
I tried new scene, there it works. I don't know why, I updated the ROPs and RTs with "match current definition", I think I am not gonna use position pass this time then .

[ricky_otoy]

Thanks for your feedback @lavrenovlad!

I will double-check which are already reported in the system and follow up. For no.2 on your list, I have yet to get such an error with the region tool - but will keep prodding.

Please PM me the scene with the Position Pass not working if you can. Thanks!

[lavrenovlad]

Okay! I'll prepare the project file later and send it to you this week.
BTW check that #5 too that I updated, about IPR reload when switching contexts. Thanks!

[lavrenovlad]

One more thing. I think it's always been broken. But there is no way to export undenoised and denoised beauty together. It seems to work in IPR that you have both, but when I export to EXR they both look the same.
AND! Ai upsampler now working, but in IPR only. When I try to render to disk, it doesn't work.

Hello - I dont seem to be able to get complex ngons rendering. Previously i'd click the 'Tessellate NGons' button under 'Tessellation' on the Geo Octane parmeters but it's not having any effect?
