Studio Lighting in Vray by Géza Kádas, Budapest Website: www.techtron.extra.hu

It is important to uncheck the "Affect Specular" slot, we don't want any specular reflection from that light ,only diffuse light.


As we can see the bounced light reaches to the bottom of the chair too. Now the lighting and the shaders are finished so lets move on to the next topic. I will discuss the settings of the final rendering.

Setting up Vray for Final Rendering

At this point of the workflow it is very important to find the balance between speed an quality. I will talk about the settings globaly, because some problems can't be solved with only changing the value of an option. So lets see the Renderer tab in this light:)



-Change the resoultion to 900x500 -Set the Adaptive rQMC image samplers min dubdiv to 2.Now thinner lines can be rendered correctly.

-Change the preset of the Irradiance map to Medium from Low.Set 50 to the HSph subdiv to achive higher quality GI.

-Use value 1200 for the Light cache subdiv.Change the Sample size to 0,006 ,now small details will be more visible. Use value 1000 to the Pre-filter option to reduce noise.We have a lot of glossi rays so check the "Use light cache for glossi rays" option./it will speed up rendering/ For the Filter use the "None" possibility.

-At the rQMC sampler use value 0,005 for noise treshold. Set the Global subdivs multiplier to 4 ,it will increase samling quality everywhere in the scene.

-You can find the Light properties in System>Lights settings. Changing the diffuse subdivision of the lights wil effect the number of the traced photons.

-Change all the vraylights subdivison to 15 or 20 to avoid noisy parts.

-Change all the materials subdivs to 20 in the Reflection section. With these settings the rendertime will increase a lot according to test render settings. Now hit F9 and wait until the calculation finishes.



This is the final rendering, no noise ,artifacts or any nerve-racking rendering trouble. A picture would not be complete without the postwork so lets move on.

Postwork

Launch photoshop, and load in the image. Because of the saturated colors of the exponential colormapping type. We need to add more character to the colors and play with the levels to achieve better contrast. Go to Image>Adjustments>Color balance.



Than Image>Adjustments>Levels



And here comes the finished picture...



Congratulations ! you finished the tutorial... I hope you liked it. ;)
