Vray2Sided Lamp [attached]

[40th]

For a while I wanted to create a lamp like this. Finally I found time to make it, and thought why not to share it. Enjoy

Re: Vray2Sided Lamp [attached]

I have noted you have Vray version 1.6.16. Is this now official download? If it is how do I upgrade?
It seems I have 01.05.30. as last version.

Thank you all for your kind words. Hope you'll find it useful.

That isn't a VfSU version, but a V-Ray core version. I also use the latest VfSU, 1.5.

Re: Vray2Sided Lamp [attached]

That number is actually what 40Th, that is the version of the main core program that we received from Chaosgroup . The current VRfSU version is 1.05.30.

Best

thanks for sharing!!! you're the best!!!
Do you mind save your model to SU6?? or could you share the lamp fabric material setting?
Thankyou!!!!!

Nice job 40th!

I've got a few questions, it would be nice if you could explain some settings:

-The lampshade seems to be a little transparent but I can't find any transparency into the material settings!
-You set the fresnel IOR of the chrome material to 24. Isn't it simplier to set the reflection to "none" insted of "fresnel" to have a perfect chrome? Can you explain this choice?
-How did you determinate to set the noise threshold to 0.008 for both Image sampler and DMC sampler? And why DMC sampler is better than adaptive subdivision for this image?
-Why did you set only 3 prepass insted of the default 4 ones in the irradiance map settings.
-Why do the omni light is set to "inverse square" insted of the default "linear"

I'm sorry for asking all this question but I try to understand really how all this "mess" (because it's pretty complicated) works.

Thank you very much for your explanations!

Re: Vray2Sided Lamp [attached]

Inverse Square is how physical correct lighting works.

The lampshade is a two-sided material - it's a special material that acts as thin translucent materials.

Hey Artchung,
I uploaded SU6 version, look at the original post.

Hey WANER_GAROUCHE,
I'll answer all your question sometime soon, I'm just a bit busy with a project O'm working on. Sorry.

-The lampshade seems to be a little transparent but I can't find any transparency into the material settings!

The lamp material isn't standard material. It's Vray2sided material, which fakes (behaves like) thin translucent material. I use it also for curtains.

-You set the fresnel IOR of the chrome material to 24. Isn't it simplier to set the reflection to "none" insted of "fresnel" to have a perfect chrome? Can you explain this choice?

I don't in this too much. The chrome mat. is the Chrome_shinny which comes with VfSU. I know if you set reflection type to none it behaves as perfect mirror.

-How did you determinate to set the noise threshold to 0.008 for both Image sampler and DMC sampler?
And why DMC sampler is better than adaptive subdivision for this image?
-Why did you set only 3 prepass insted of the default 4 ones in the irradiance map settings.

I used settings that won't be long on rendering time, but still look decent.

-Why do the omni light is set to "inverse square" insted of the default "linear"

To tell you the truth, except of making this lamp I also tested all three Omni's decay types. And "inverse square" decay was behaving the closest to what I wanted.
