How to make a Chandelier

[pradipta]

I have made a chandelier for an interior scene but is not glowing properly as it should be. either it's going too flat and white or looking blackins.

what setting are required for the shaders when i am using vray. can anyone help me out on this? Thanks

I set chandelieres to NOT cast shadows, only the ceiling cap. It reality, the shadows are so soft and broken up that they aren't noticeable. And if you would have a strong shadow its going to look awful in a rendering. So I put a few omni type lights in the model and leave it at that.

Thanks Ernest, i was trying hard to make one good looking chandelier but rendering was not coming up properly. i also made the shaders to lok like crystal but still it was coming dark... i will try once more now as you mentioned.

Ernest, tell me onething regarding vray. can LC or IR setting give same output in different resolutions? for example i am doing draft renders in 600 resolutions and for final can i use those same settings for 720 resolution? or i have to make some modification in the LC and IR setting? i am confused little bit

Pradipta,

I am not the most versed guy in this issue, but since I had that same question a few days ago, let me tell you what I found from Cristopher Nichols in the chaosgroup forum: "every time you go down on the min/max setings you effectively cut the resolution of your irradiance map by half, so techincally speaking the Irr maps of these would be identical:

 

min/max -2,-1 at 400x300

is equal to

min/max -3,-2 at 800x300

is equal to

min/max -4,-3 at 1600,600

 

and so on and so forth.

 

As far as the lightcache, I've been using lightcache maps half the resolution of the rendering I want. Bue I dont know if this is correct.

 

Hope this helps *And hope I am right about it!

Lightcache is resolution independent. More on the subject:

Ernest, tell me onething regarding vray.

 

OK, vray is a very popular product.

 

I don't yet use vray, I was just commenting more generally about lighting from chandeliers--I'm working on one right now, and also the project before that.

LOL nice one.

Bayvan:

i will read the manual on lightcache in a minute, but maybe you know: if the lightcache is resolution independent, why would I want to render any lightcache beyond say 640x480?? No reason, right?

I'll read the manual anyway, which I did a year ago, but didnt understand much:confused:

Check the link it's not exactly the manual but some examples that can give you prety good idea why and when to change the settings of the LC. My English isn't very good and maybe the thinks i wrote don't explane the concept as clear as it is in my head so that's why i put the link for the examples. But never the less i still hope that i can be helpfull to the vray users.

Best regards,

bayvan
