Hi
IR updates every time when any maps are loading to Material Editor.
For example if IR started and I open SME, IR starts to update picture continuously wile all visible in SME’s field maps are loading. After all visible maps are loaded, IR continues to render normally. But if I pan in SME and some new map starts to load, IR updates again and again every time something new appears in SME field.
Finally I found the object, which somehow causes this issue - it’s Forest pack object. In this example scene FP object doesn’t have any linked objects but the fact that it is in this scene is enough to get this issue. To see it, please, start IR, get any material to ME/SME and every time when this material updates, IR updates picture too IR-material_update.max (340 KB)
