Shadow Insanity!

[Poll]

I must admit, that shadows are a b*tch, but this time I really don't understand what’s happening.

 

In the attached image you see an object that should cast shadows on the wooden floor, but it doesn’t. I thought, well maybe the object doesn’t cast shadows, or the floor doesn't receive them, so I added a dummy object. This one casts shadow and RECEIVES shadows from the problem object.

 

So the case is an object that does cast shadows, and a floor that receives shadows, but not from each other?!

 

Anyone.. please..

 

Thank you in advance!

Hmm.

 

Can you replace that floor with a new, solid plane and see if the wall then casts shadows?

[Poll]

Hi, well.. i did that ... it gives the same result. I added a solid box, with standard vray material

 

I don't think it has anything to do with the material, cause I tried several.

I'm losing my mind here :S.. It seems that when objects reach a certain height they start casting shadows, so I thought maybe it had something to do with the vraysun target? .. its a standard light setup (Vraysun linked to daylight system).

can you post the file?

Hi friend! try this:

 

First, check the bias parameter in your sun light. It should be in 0,2 meters(near or less).

Second, check the object properties to verify if the option "cast shadow" and "receive shadows" is enabled for both objects.

Third, Good luck!

Fourth: Good Bye!

you can also try to use "single frame" in irradiance map. and reset the current irradiance map saved before you start a new rendering..it happen to me once.

hope this helps

[thierrybauwens@inpix.be]

maybe you should return the faces of the wall, if it is single face material...

[Poll]

Thank you for your help Brandon, Claudio, Wimpy and Thierry!

 

But my friend Claudio, you hit the spot! It was the bias in the sun! I had it at 1,0 meters thinking the shadow bias only affected the hardness of the direct shadows, and not whether or not to cast it at all! When I changed it to 0,2 it worked like a charm!! So Thank you very very much!

So here it is:

sometimes a bias of 0.2 is still too high for me, so i am getting "floating" effects.

 

i usually set it to 0.05 or lower.

Just a quickie..

 

Where did you get those people from in the final image.. the silhouetted ones..?

 

Been looking for some like that..

 

As for that sun bias.. all makes sense now..

[Poll]

a quickie right back at ya

 

The people are photoshopped, just a cut out silhouette with a white outline stroke

 

sun bias.. aahh

Ah.. cool.

 

I like that idea.....

that tree looks awesome! great leaf material

Yeah where did you get that tree from?

[Poll]

Wow thank you, well the tree is from Archmodels vol 31. Nicely modelled trees and foliage that I don't have the time for to do myself.

 

BUT, I don't like the supergreen textures that come with these models, so it has a HUE shift of minus 10, and some desaturation. This trick works great on all too green/plastic trees/foliage.

 

Here is a render without the hue shift and desaturation (see the difference with the first one)

and a bonus (not really nice to post it here I think) the interior of those appartements in the background
