Advice needed on Vray Interior Scene

Recommended Posts

Hi there

 

I am creating an interior scene of a joint living room/dining room.

 

I have a few windows and doors as well as a skylight but am having a problem with the sun creating really strong bright rays on the ground and the wall when it is coming through the windows, which seem out of place and don't seem to blend in well.

 

Currently i have the vray sun set too:

 

Intensity - 1.0

Size - 5.0

 

Everything else is default.

 

I have attached a render to show you what i mean.

 

Any advice on how to reduce the strength of those rays to give it a more realistic look would be great.

 

Many thanks

Yes - put vray sky portals on the INSIDE of the windows and set them to SIMPLE.

Lower the intensity of the sun to around .55 (youll have to play with that)

 

Then, I would use reinhard as the colour mapping between 0.1 - 0.3

 

That should give you a solid base

I put sky portals in front of the windows but it still seems to give quite sharp lighting.

 

The first image is with an intensity of 1.0

 

The second image is with an intensity of .55

 

I kept the color mapping with exponential because it seemed to spread the light out a lot more.

 

Would moving the sun have an effect. As you can see from the scene images sunlight rays are going to come in from at least one angle?

 

Any other ideas?

 

I've also attached some screenshots of the scene as well.

that looks better - just change your white balance on camera. Put a white sphere in middle of room and set colour to 255. Do a quick render and then go to camera settings and do custom color balance and color pick the ball (try and pick the most common diffuse colour on it if that makes sense) and then drop the whiteness value about 20%.

 

It could also be your scene units. Are they correct?

 

This is with the burn value 0.1 and intensity of .55

 

It seems to work if i decrease the multiplayer to less than 0.1.

 

Problem i have then is the scene seems to be a lot colder but can probably adjust that in post.

just check that your building is the right size (ie that the heights of the room are right, ie 3000mm not 300mm) - if its out of scale it will cause you problems.

 

Yes, with skyportals, you dont even need the sun on. You can leave it off to simulate an overcast'ish condition. so if you leave it on 0.1 or even lower - it will be fine.

 

NOW - you must do tests in colour because it will be different when you use solid textures.
