Hi there, I recently started using the MPlay IPR instead of the Custom OpenGL one (camera movement updates are more responsive there for me) and I'm wondering a thing: why does MPlay become unresponsive and use a ton of CPU when I try to stop a render there (using ESC or the big red X)? The CPU usage shoots very consistently to 28-29%, which is a weird amount I feel as I'm on a 4(8) core i7 CPU.
It would be very helpful sometimes to be able to pause or stop renders but still have the (partially) rendered image left in MPlay, but right now I have to kill MPlay using Task Manager to later be able to start rendering again. Wondering if this is a current limitation of the plugin (platform specific maybe? using win10) or a result of something weird I'm doing? Perhaps there could be Pause and Stop buttons in the newly introduced Octane IPR -shelf?
MPlay IPR pause/stop question

Hi,
It is weird what you say about the OpenGL responsiveness. Do you have only one GPU, used also for the monitors? In this case, you should try to set the render priority to "low" to see if this helps.
I'm not sure why MPlay has this behavior when you stop the rendering, but this is not something related to the plugin. I suppose that MPlay is doing something in the background, like store the image in the cache, or something like that. Anyway, I'll investigate it.
You can stop the MPlay IPR rendering using the "Esc" key or the "Halt current render" top icon, but later you are going to need to click the "IPR" icon again to start a new IPR render session and continue rendering. I could check if the OpenGL IPR pause function can be added to the MPlay IPR.
Thanks,
