are you rendering only with max or any plugin?

[Ky Lane]

Up your GI and lower your sun light... and up your camera exposure values.

[odouble]

What Vray settings are you using? Are you using Vray sun and environment also? My hunch is that your setting should not be as high as you have them.

[manta]

try this one...

hi,

i feel there is a problem with your light , try filtering all lights in your scene and delete them. then try from the begining to add one direct light instead and observe its reaction.

[odouble]

I don't think there is much wrong with your settings. It just might be your geometry that is messed up.

I have attached a simple scene with a 1 camera, 1 vray plane, 1 skydome with vraylight material mapped to it and a 1 vray light (sphere) as the sun. This setup is easier for me to control when doing exterior lighting.

I used irradiance map (low) changed HS.ph subdiv lower to 30 for primary bounces and light cache (see file settings) for secondary bounces. This is a good test setting and took only 14 seconds to render on my computer.

I also attached the rendered image.

[manta]

Are you using vraysun ?

Are you using Vray physical camera ?

[Ky Lane]

For the sake of sounding stupid, have your right clicked a viewport and gone to "convert scene to vray" - just incase theres some odd non-vray happy material or light in there?

[Ky Lane]

Have to say, Im not a fan of vraysun. Id kill it, and remove the environment map too and make your own. Use a Direct light using Vray shadows, for your sun and just use a gradient for your background.

 

At the very least, drop back the intensity of the sun a bucketload, and drop your color settings. Set them to exponential, drop the light and dark multimpliers to like 0.75 and the gamma to 0.8? See what happens.

[Ky Lane]

You dont seem to have any GI... whats your environment settings under Vray?

[Ky Lane]

Shadows look alot better though.

 

Drop the contrast settings for the dark multiplier.

 

Update : try using/understanding the attached files.

With that attached scene... if you want lighter shadows, up the environment GI, and lower the direct lights intensity... if you put GI to 0, the shadows (unless theyre receiving a light bounce from somewhere else) will be black.

[Ky Lane]

Did you try my file?

[Ky Lane]

Anytime mate. You just need some more GI, but watch that youre overshooting/saturating the image - its a juggle between GI/Sun/Exposure.

[Ky Lane]

Ah. Im on Max 2008... Ill see if I can save back...

[Ky Lane]

No I cant... Ok...

 

Attached is the settings file.

 

Open a new max file. Merge your current file into it, excluding all lights.

 

Open the rendering flyout, and load in these vray settings.

 

Create a direct light, set shadows to Vray... set its intensity to 0.8. This is your sunlight.

 

Hit render, and lets see what happens...

[Ky Lane]

problem...

my file is full of vray proxies... if i merge the file, it only loads the trees.... ill just try the preset in my original file...

 

 

Darn...Ok... Good luck.

[Ky Lane]

Geez man.. someone doesnt like you

 

Im jsut finishing a big job. When done Ill shoot you a JPG with all my settings.

 

Shoot me your email in PM. Quicker. Ill post the eventual solution here for others.

[odouble]

Hey, my file is max 2008 so that's probably why it didn't open. I will post some basic test settings for you soon.

[e_cbautista]

sometimes max messes up with the lights & shadows, select all the lights and delete them, start afresh installing lights starting with standard direct light (vrays shadows on)/ or vray sun. your environment (press 8) is too dark for an external scene.

 

try doing a test render with the lowest setting- say GI on, Vray Image Sampling: Fixed/ Area, Pri & Sec GI using LC. you could also tick "Dont Render Final" from Global Switches, save map for the LC. Just uncheck it back from Global Switches and use the recently saved map when you do a render to check lights & shadows.

 

hope you have asked for an extension of your deadline.

[IHAB]

sometimes max messes up with the lights & shadows,

yes, it happens.Be sure of your model scale(generic/metric....whatever),just a thought came accross.

[Mike.]

you should not engage you in a work with deadlines with a render engine you don't know at all....

the problem seems to come from your environnement settings.

[odouble]

Use a vray light (sphere) instead of a standard max target light. I would make the light color a light yellow/amber. Are you using any environment light/skydome? You should probably have just 2 lights for a simple exterior setup like this.

 

Can you post a wireframe of your setup from an orthographic view (right or left) with your whole scene and light setup?

 

What are your unit settings for this scene?

 

I have attached an image for basic vray light settings. You can adjust them as you need.

[odouble]

Can you take the same wireframe and put a helper tape object to measure your scene across I am curious to know what size and units the scene is? Post a shot of the modifier panel after the tape helper has been created so we can see the length. If that turns out fine, I would redo the entire scene with no proxys. Just load the buildings and landscape with no trees and then render.
