[HOU-1461] IPR refreshes too often. It should only refresh when the change effects the pixels.

[stevejjd]

Hi guys, just reporting that the IRP refreshes way too often. It should only refresh when the change effects the pixels.

For example, renaming a node should not cause a refresh but changing the color should.

Also, when I use the region render with IPR there is a bug. I use render region then stop the IPR then start the IPR, it doesnt use the render region.

Hello stevejjd , I've reported first issue, about IPR restart on name change, but couldn't reproduce second one. What are your OS, Houdini and V-Ray build numbers? Or if you can send me a scene where region ignore issue appear.

Houdini 17.5.360
Windows 10
VFH [Info] * Build number:6048 hash:507ddaf from 13 Dec 2019 04:16

This happens on any scene including ones that have not been saved.

Thanks stevejjd , I've reproduced it only with new scene and only after the first render region selection. HOU-1465 is the issue number in our system.
