Title: UVW Randomizer Bug ?
Post by: brr on 2021-06-08, 09:37:38

Dear Corona-Renderer Team,

I have a scene, where I am using Corona UVW Randomizer for a bunch of objects. (Some stucco and stone tiles etc.)
If I simply rename this object, then Corona UVW Randomizer makes new variation, which is pretty strange... When I change the object name back, then the UVW Randomizer map generates the image like it was before.

Maybe, for most of the projects it may be not so important, but in my case, it completely ruins the flexibility, because if I let say want to make later object naming more logical, then I will have another visual result.
I am making one 360 degree tour Project, where I have almost 20 high-res panoramas, and it is really important to stay consistent in rendering results. (Especially for later region-like edits).

Please, see attached images and scene.
Max 2019 SP 3.4, Corona 6 hf1

Best Regards

Hello

Sorry for bumping this. It will be really helpful if devs or forum users confirm that this problem exists. Or maybe I am simply doing something wrong and have this issue ...

Thanks a lot in advance

Hi,

So I can provide a bit on info here.

This is in fact expected. "Instance" randomization is based on a node name and will change when the node is renamed, unfortunately there is no way around this.

Thanks,

Rowan

Oh, thanks for the info !
Now I see that for instance mode in corona 8 we have a nice tooltip with a note about exactly this behavior .
