Flickering?

[St Cana's]

Hi guys... and gals

Any ideas why the brown texture is flickering? I'm not actually sure it's flickering in the 'GI' sense of flickering (looks more like 'crawling'), but it is a flicker of sorts. I think it's something to do with bump as the yellow texture is stable and that has no bump. Love Vray, but why so many controls!

you used a noise for bump, right?

Could it be that you set the noise to World? Because then you are "driving" through the noise.
Another pitfall, by default a slight noise movement is turned on.

Hi Walli

Yeah, the bump is noise but it's set to Texture not world. I thought you were on to something there for a moment!

I thought that 0.001 of movement that's set by default didn't make a difference as the speed is set to 0%. I shall try another test with that set to '0'. My only suspicion is that it seems like a very small amount of movement to cause such a lot of 'crawl'.

Thanks for the reply.

Nope, wasn't the movement thing. :(

Has anyone else had any problems with noise as bump? If, indeed, that's what it is...

[Walli]

have you tried to set to object? does this make a difference? Does this flickering also happen when rendering with C4D default renderer?

[St Cana's]

I'll try that.

Thanks Walli, perfect answer! Seems so obvious now - I feel a little bit Duh...

I am not sure , but actually I would claim you shouldn´t feel Duh ;-)

As Texture is child of the object, it should move together with the object - at least that´s my understanding.

In this case this would be a Vray problem. But I would have to dive through the manual ;-)

I'm looking forward to the day we get just one big red button that says RENDER so I can get on with making art instead of worrying which drop down or dialogue I've missed!

Thanks again

sorry for picking up this old thread. it's more of a general c4d question. is there a chance to edit such default settings? make them 0.000 forever?

P..:

[St Cana's]

It wasn't the setting that was the problem, it was that the bump was set to 'Texture' when it needed to be set to 'Object'.

EDIT: Actually, I didn't answer your question. I'm not sure if there's a 'by the book' way of doing it, but you could save a new master file that had a material in there with the settings as you want. Then just use that material as your starting point every time. Although, as I said, that wasn't what was causing the problem.

As far as I know, this is not possible.
You could save a material preset, though, and load it with specific settings whenever you need that noise.
