Hi
Something seems to have gone seriously wrong with CoronaUvwRandomizer map. Plugging the the same output to different slots yields different randomisation values. This is bonkers. Or am I going mad!?
without CoronaUvwRandomizer map:

with faulty CoronaUvwRandomizer map:

Is there a fix for this?
Thank you,
Marek

Hi, something does indeed seem wrong here. I tested this myself with both corona 6 and 7(hotfix 1), and it seems that displacement "ignores" the CoronaUvwRandomizer map.
However I can see that the "Autobump" part of the displacement is being randomized correctly.
This is leading me to believe that this is an order of operation sort of deal. Aka that Corona calculates Displacement before the randomizer, and the Autobump after.
Weirdly enough I did get it to produce expected result when using "Primitive" on the randomizer "Mode". But this is a pretty weird way to randomize something so not really helpful.

Yep, see:

Ah, yeah this is apparently not a priority. We'll just have to hope!

Hi everyone, I will see if we can bump this up.

Hi George
Yes, please see to it that it is fixed, if you can. For architectural viz firm, dealing with lots of displaced walls, UVW randomizer map is (or was) a daily bread and butter. It is hard to accept, that something that worked great right off the bat when first introduced, got subsequently cocked up beyond use. What are you doing Render Legion? trying to outdo Autodesk in their own game? Chaos trying to grind you down? C'mon. That's not what Corona stands for, right?
I am not even going to comment on Corona converter messing up conversion of simple corona legacy materials to physical ones. that's too much. leave it for some other rant. For now could you, pretty please, fix the uvw randomizer displacement issue?
Hopefully,
Marek

1) I haven't checked this right now, but I think this is not working correctly only if the UVW randomizer is set to "mesh element" randomization mode. Isn't it?
2) "something that worked great right off the bat when first introduced" - has it ever worked differently than it does right now?
-
Hi Maru,
1) Yes. It fails only in mesh element mode
2) No it has never worked with displacement since it has been introduced. Went back until v5.2
Good Luck

Good to know. I'll keep an eye on this.
