IPR Workflow *FIXED

[daryl.dunlap]

Testing against Mantra ROP behavior:

• When Rendering to Custom OpenGL - I cant see anything (intuitive) to stop the IPR render. When Rendering to MPlay, the Halt Current Render button and its HotKey (Escape Key) stops the IPR render.
• Mouse Scroll - When rendering to MPlay, the IPR responds very smoothly to Mouse Scroll and does not lag when Mouse Scroll events are created quickly. When rendering to Custom OpenGL, the IPR is very laggy and seems to que the Mouse Scroll events sequentially - such that, if you close the Custom OpenGL window PRIOR to these Mouse Scroll events being processed by Custom OpenGL, you receive the following popup:

Hi,

I suppose that in the OpenGL window you could use the "Pause" button to stop the rendering. Internally probably from the GPU point of view it is the same that stop the rendering.

Let me check why the OpenGL IPR has this behavior, perhaps it is a side effect of the raw OpenGL window running over the Houdini OpenGL viewports, but I'm not sure.

Hi,

The slowdown updating the IPR while interacting with the camera in the viewports should be fixed in the next 2018.1 plugin build.

Thanks,

Hi Juanjo,

I can confirm the slowdown of camera movements in the IPR window as compared to the MPlay one. Coming from the C4D plugin, I have to say that things are almost realtime there. Any chance to make things as responsive in the Houdini plugin as well?

Also - probably a super-noob question - is there a way to dock the IPR/MPlay window somewhere in the Houdini interface? In C4D that works. Having the window floating around in Houdini is OK, but having it part of the interface would be a bit more elegant.


Thanks for letting me know!

This camera IPR performance issue has been already fixed, and it will be included in the next upcoming 2018.1 plugin build.

About the dockable IPR window, this is a feature that will be available once we have the whole IPR window system refactored from the current raw OpenGL window to a Qt5 window, something that is a planned feature to be done along this year.

Thanks,

Hi Juanjo,

Thanks for the update! Looking forward to the new IPR window then. In the meantime, is the Houdini 2018.1 update available for use already? Would be great to try ot out.

Not yet, probably I'll release it once we have the new 2018.1 RC2 core build later this week, due to the large number of issues that have been fixed on it.

Thanks,

Fixed in 2018.3
