grainy aluminum

[noobert]

Percy, you are da man!
I just set the lights inside the blinds and it works the grain dissappeared,
There is still a very little bit of grain but I think with more refl. gloss. subd.
this will go away too.

I can't say how much I thank you!
I never would have realised that the blinds were the Problem, I could have reseted vray twice and tweak every param. in the mat/render settings and surely would have gone crazy about that!

I want to thank all people that posted here!!!
and especially Percydaman!!!

Way to go Percy!

What if you just exclude the blinds from generating GI and leave the light outside? Was there glass in the windows? Sometimes that will cause noise if it generates GI.

glad it helped. I tried alot of tests but could never get rid of ALL the noise, which was annoying because that doesn't seem right. Its gotta be something with the lighting, Im not sure. Definitely strange. Adjusting the QMC parameters, helped a little, but the render times jumped alot.

thats true!

I've tried that and it seems to eliminate the noise a lot! But of corse it is much darker and the rendertime seems to take a good bit longer!
No there is no glass in the windows yet.

Greetz People!

I LOVE THIS FORUM!

haha, how do you think I found the problem?

First thing I always do is use the Override Mtl in the vray global switches, and give everything a nice gray vray material and then rerender. Having done that, thats when I saw that bad black mange. Thats when you know its not solely attributed to glossy reflections.

Replaced all geometry and rerendered, still bad. That tells me its not necessarily geometry related. Hid the blinds and it went away. That pretty much told me what was causing the issue.

Didn't happen that quick of course..lol played with it for a few hours while watching the world series.

Hi there!
Here is my last render of the shuttles (still WIP):



I am happy with this and I would like to thank you all for you help!

maybe someone could use this office chair I've made for the scene it is not the cleanest mesh but it looks like an office chair

If somebody has suggestions what i could do better with the barebones please let me know it!

Greetz and thanx again!

wow good work! turned out great!

[Trapezium]

Looks great! I wonder if those little guys would be a good solution for a render farm?

they are certainly small but have disadvantages.
like i have a damaged shuttle here that wont boot and i have no idea how to fix it because the mainboard and psu are not standard parts. they are also quite noisy under load.
for a render farm they are also too well equipped, they have a lot of stuff and connections onboard.

[Trapezium]

Good points Well taken. I'll probably still check around to see if there are any less equipped/ more stable brands though.

@plastic_: let me be a clairvoyant - your dead shuttle has an nvidia chipset hasnt it ? If so, you are one of thousands of people who had the same problem (me too) What I found out is that it has to do something with the nforce chipset and it is not shuttle related, I have an ASUS A7N8X-X (atx motherboard also with nforce chipset) that died in the same way. In both cases my dealer exchanged it without any comment cause they already knew the the problems. Have you tried to get a new one for your dead shuttle?
Loudness: thats true for old revisions but new versions are realy quiet
for example sn45g v3.
too well equipped: thats absolutely true! but they have two quiet simple versions, without this horrible nforce chipset, the sk41g(athlon) and the sb51g(P4) they have onboard graphic ( who needs more for a renderslave?), lan (thats useful!) fire wire(not needed) optical in and out (also not needed) onboard Sound (also not needed) on the other hand they cost only 170 Euro! add 100 for the CPU and 80 for 512 Mb ram (no harddisk cause you can do network boot) and you got a cool looking and fast renderslave for 350 Euros. I've got a computer room now ( )
where all computers have their place but if I had to put my renderfarm in my living or office room I would always take a barebone again!

greetz and sorry for the bad english!

Could we have a summary on the exact settings that should be used for smooth, soft reflecting metals. Its a little unclear what I should be doing. I always have issues with this grainy metallic appearence, and I don't have blinds to move the Vray light in front of!

I just created a chamfered box on a Vray plane and applied a soft reflecting metal material to it. When rendered, with various settings, I always get grain.

Any tips?

[noobert]

what are your refl. subdivisions?

[ezrhythm]

wait wait wait!!!

LOL

sorry, great IMAGE! luve the work!

but DVD drives are way out of this world? were they polished? they never reflect like that... thats the first thing punched my eye... ouch

innnit?
