Interior Render

[alejandrofernandez]

Hi, I always seem to have this problem with my interior renders. The ceiling always looks darker than the walls, I`d like to know how to lighten up the ceiling. Im attaching the image so you know what Im talking about. I always fix this in photoshop, but Im sure there has to be a way to fix this in 3DMAX with vray. Help!

 

Thank you!

I think darker is correct because your walls are receiving more light. You're probably never going to get it right (to get the effect you want artistically) so I always composite. I also find lighting it separately with a light shining up gives a nicer tone.

Sorry for hijacking the thread.

@hani30: for the stone wall on the right next to book shelve, did you use displacement or geometrically carved it? :-) you got a nice surface texture there at the meeting point with the window frame & have a well corner joint. How dis you do that?

I just googled "office" to find an image to illustrate my point. I thought it was a photograph.

The top of the chair fabric has wrinkles.

Here's another shot but with the desk a different color.

I just saw them on smartphone, so it is hard to really see whether its a photograph or a CG. But i'm pretty sure it is a CG render based on the mouse cable wrinkle there.. (It is identical :-))

Agreed. I´m going to try adding light shining up and see how that works out. Thanks!

It is true, that sometimes depending of your light situation you will need to use hidden fill lights, just like a photographer would do. but it is also true that setting correct materials also will give you better light bounce in your scene, try to not use pure black or 100 white materials. Also several materials that seems to be 100 matte in reality they are not, this will also give you extra punch in the light.

Check your light intensities and exposure.

I do a lots of interiors for schools and hospitals, windows and open spaces are limited in most of them and still is very strange when I have to use a light pointing the ceiling to compensate lighting. actually I can't remember when was last time I used. My fill lights are more to create color variation of fill dark corners in the building.

If you are rendering your room alone, not with the rest of the building, remember to place a big plane under your room as a ground, this will help you to bounce the sun light up to your room, portal skys also will benefit from this. If you are using V Ray, using a V Ray infinite plane will work great.

The infinite plane worked! Thanks! About the hidden fill lights, do you just use Plane lights or spheres?

[Francisco Penaloza]

it depends the light that you want to create, if you need to fake a window light, then a plane light will do, or a soft box light.

if you need to fake a accent light, or lamp then a sphere or omni light will do fine.

remember is you are using omni light to check decay and V Ray area shadows.

Do it in post....

[inpow watir]

By the way, the ceiling looks pretty much natural to me

[alejandrofernandez]

Do it in post....

 

I did! It ended up looking much better thanks to all this suggestions, I´ll put it up here soon.

After doing some research I finally found the right way to make my ceilings look lighter. The problem was that the flooring was reflecting on the ceiling, so what I did is, selected my floor material box in the material editor, clicked on the VRAYMTL button and select VrayOverideMtl, in the GI tab I created a white VrayMtl material and done

You can also use a vray wrapper to boost the gi received by the material. That's what I do in these situations.
