Hiya,
Sorry if this is in the wrong section.
If I merge in a tree from Archmodel trees 176 (for example), and use the Corona converter with the 'Bitmap to CoronaBitmap' option enabled, my viewport becomes quite jumpy/laggy/hiccuppy after the conversion. Even if the material is removed from the scene, the problem persists. Merging an affected model into a fresh scene doesn't help. Quite strange.
I think I've narrowed it down to the vray2sidedmaterials within the multi/sub-object material that comes with the model.
It also seems like the more of these materials that are present in a scene, the worse the jumping/skipping.
Using 2016 sp4
