Now that almost 80perc. of my materials feature Randomizer and Triplanar, often both in row, that is not nice news. I did want better representation in viewport (just by taking any bitmap in chain), but if it's causing performance issues now : /

https://forum.corona-renderer.com/index.php?topic=41834.msg221045#msg221045I am sure it was scene/object/material specific, so no worries.
I have bunch of scenes and in 99.9% of them all materials are set with Triplanar, MappingRandomizer combination, many of them with CoronaColorCorrect. The mentioned combination is present for sure. None of them has ever caused slowdowns.
I even, just to be sure, dared to open one of the current production scenes of mine and applied to all objects the mentioned material with bad combination. Guess what - the viewport 40-50fps (heavy scene), with bad combination material became faster.
So, really nothing to worry about. I really believe this was scene specific, as tested and confirmed.
