Floor Plan 3d Section Lighting

[georgeworton]

Hi guys,

 

Im new to vray rendering. I understand the basics but I'm having trouble getting the right lighting for my model. Im tring to render a 3d floor plan of a public toilet but cant figure out how to show whats there without it being to bright or dark.

 

Would a sun be better than a light? ( I dont really want shadows)

 

Thanks

Why don't you post a picture? A light should do it - you can turn off shadows in Global settings and you can adjust the brightness

of the light up or down.

Hi,

 

Yes absolutely use Vray sun and about the camera go for V ray physical

Yeah thats what I do, but is it an idea to play around with the colour of the sun? And which attribute mostly affects the powerfulness of the sun?

Without getting too technical : The Vray Sun / Sky combination automatically affects the light colours to correspond to the angle of the sun. So a low angle more closely replicates dawn dusk colours and at a more vertical angle (like mid-day) the colour will be more blue. There is control that can be exercised over this by various means but perhaps until you're confident with it's more general usage it's best not to go there just yet.

 

Light intensity can be controlled by the sun intensity multiplier and the sharpness of the shadows by increasing the size of the sun size multiplier. The larger the sun, the softer the shadows of course.

 

With a Physical camera set to normal SLR camera type aperture, shutter & film speed settings the sun should give you a reasonable starting point with an intensity multiplier of 1. You can of course thereafter adjust the lights to suit and there's a book in the options for achieving various lighting effects but I'm just concentrating on a starting point.

 

Generally it's considered good practice to achieve a reasonable balance of lighting between the various light sources and to use the camera settings to achieve your correct overall lighting levels, but - each to his own - there's plenty of ways to approach lighting your scene and many posts and tutorials to give you more fuller guidance.

 

If you want no shadows though.... you may be better with just vray plane lights and no sun - unless there are lot's of windows visible.

I can't tell if C G is being serious or not. This is a floorplan of a public toilet, right? You are using Vray with GI and sun/sky system active but don't want shadows?

Seriously, import it into the free version of sketchup, switch to a top view and call it a day.
