Gloss material again?

[radimek]

I am completely perplexed by way to achieve glossines in vray renering.
I was watching thread here, created vray materila with light gray reflection, 0.8 glossiness. It loks good in material editor but in the rendering it is just flat. The i tried standard with glossiness and specular reflection, sae result. Could anyone post material/ setting to achieve gloss floor (wood, tile) and or chrom/aluminum?

Perhaps there is some setting in the rendering which makes it not working....


Thanks, Radim

Make sure you have some environment (image or real geometry) to reflect into your glossy object.

[losbellos]

vray free or demo/advanced? or which one you use?

Well, if u use vray free...>
standard material, add some flore texture in the diffuse slot, then
go down to the maps tap click on reflection, add a vray map to it, in the vraymap rollout set REFLECT down you'll find glossy I think 100 (default) is sufficient for start, then set the subdivs to 5 - will be fast. So then come out of this and set the reflection 30 in the maps rollout (where you add the vray map)
this should be a good start, you can then increase decrease. I made a testrender of it. Wil be fine.

sorry for the popup, I choosed a wrong site.

Thank you all for reply. I use advanced version. I will try the standard materila. I have also downloaded some vray materials of other users and they are reflective in the scene, which means it is a problme of material setting. BUt I can use those as base to work from.

Thanks again.

woah woah. if your using advanced then dont use a standard material
use a vrayt material. turn up your reflections using the color swatch. closer to white is reflective. then take the glossyness down rather than up. something like 0.8 is nice. then lower your subdivs to something like 3 and then start raising it till you get a nice result. and voila. you have glossies

[radimek]

To Da_Elf. Thanks. You sort of answer my question before I could post it. I was wondering about speed of standard versus vray material. This image 1024x768 took 1 1/2 hours to render with glossy floor and column ( no glass in the scene, one light with vray shadow, P4 2.53 1GB RAM. Seems much longer than the time you guys posting here.

vray: irradiance map, direct comps for seconfd bounce, medium preset.

Oh, I forgot, which of the parameters in vray material influance the blur of the reflection? Is that the map percentage or the glossiness factor or the cuttoff?

It's the glossiness.

radimek, I'm still in the very begining and put too much lights on my scenes and that makes rendering slow and can get the efect that I want.
My qustion is how do you put ONE light and get this efect in this scene that you posted here?
Thanx

well if you are talking about getting an external light into an internal space, you need good openings and a nice strong light, and you have to bounce the light round the space, the more bounces the more light will affect the internal surfaces. and then you can use colour mapping to get the general brightness up....... well thats what i do any how

That's how I do it. I pick up viz sun, change shaodw to vray,s et up medium set and voila. This is a beauty of vray, it works most of the time very well. Originally I was using high dark and light multipliers but I leraned here that's what causes extense color bleed, so I just bump up the sun lux value.
(I removed glass from opeinings prior to irradiance map calculations)
