White Room Rendering

[conceptdesign]

Morning guys - I have been asked to do an all white room for a trade show booth image and would like to know the best way to proceed - The room is a basic office space but all materials are white and greyscale - Any tips on how to light such a space to get a clean crisp look - Also any tips ofr material setup would be great since grey materials usually lead to a cold lifeless space - Thanks

Initially, my basic interior lighting approach wouldn't change from the norm, except perhaps no colored lights. Once the general lighting is good, it would be fun to use Vray/GPU to adjust the materials and lighting until they look they way you'd like. I don't know if you can use any color at all, but warmer greys are on the yellow side, as opposed to cold/blue -- apologies if you already knew that.

For the lighting I would emulate the way in which most office spaces are lit in the real world - a grid system of fluorescent luminaires. Create an array of rectangular Vray lights roughly similar in size to common light fittings (1500mm x 200mm should do it) and space them apart 3m or so. The crucial thing is the colour temperature, set it to about 5200 if you want a slightly warmer feel or 6000 or so for a cooler crisper light. Alternatively find an image of an actual T5 lamp or diffuser (switched on!) and map it onto the vraylight as this should give some subtle colour variation in the lighting.

Thanks for the tips!!! I will post some results -

Without seeing a layout i think trying to help light an area is going to be all over the shop....

Basics -
At the windows - vray plane lights - either a value or skylight portal with vray sky (sun on or off)
- IES lights if there are ceiling downlights. colour temps 3500-4500 for a warm yellowish - 5000-6500 cool white / careful with the intensity value on 6500..It can be overkill..All dependent again on Vray Cam Settings.....I do alot of interiors and from learning all these values mentioned work perfectly with an F4 - Shutter 10 - 100...test each one till you like.Film ISO 100

Im presuming a gamma 2.2 type setup - Reinhard burn value of 0.05 - 3 should help control the burn on the whites - adjust the levels after in photoshop or VFB to boost the saturation / colour balance

My main point of advice but i may be wrong..is set the lighting up on a typical 200 RGB colour Override.Once you have a nice balance in the colour temps, this is obv dependent on the scene and the look required..Adjust your Override material up to a white in increments until you start to get a white you are starting to feel looks right.

Or get some samples online and im sure there's many that will advise
