Burn problem and clip planes problem

[Dave Buckley]

guys, i have two problems in this image, the room is tiny in terms of getting a camera in there so i am using clipping planes on my vray camera, however as you can see i am getting this cutoff effect in the bottom corner, i can't reduce the clipping plane anymore as the wall will then come into shot, is there any ways around this???

 

Also i am getting way more burn around my window then i would like, i am using reinhard colour mapping with burn set to zero.

 

at the minute there is no glass in the windows, if i put glass there, will it control the burn a bit, as i believe i can't get any less burn than zero

To be honest, I'd fix the clipping problem with Photoshop. As for the burn issue, put the glass in and see what it does, then approach it from there but always remember that burning occurs in photographs as well as CG and it isn't always a bad thing...

because the direct sun isn't that obvious, i've just turned the sun so it is pointing away from the window (no direct light) there is nothing in my brief that says they want the sun shining through the window. i also think it will disappear when i get correct materials on there.

 

so clone stamp for the clipping issue right???

 

what do you think to the composition of that shot, i'm finding it quite difficult with the kitchen being really small

[shaneis]

Clip - you could use the clone or marquee around it and scale it to the left, or marquee/copy/paste, or marquee and smudge, or.... you get the idea. it's a small fix, so what ever's quickest and easiest.

 

Burn - if you think the overall shot will look better without direct Sun, then move the Sun. If you think it would look great with a nice bloom of light hitting the bench top, then leave it as it was. Don't compromise your composition because you think a bright spot is a bad thing. That's why I linked to Fran's images - without the "burning", it wouldn't be as beautiful an image as it is. Personally, I think the lighting would look much more dramatic if the sunlight was lower in the sky and was cutting across the room to catching the corner of the wall on the right-hand-side... but that's just my opinion.

 

Composition - You're right, it is a tough room to sell. If it's just a render to show the space, then I think what you have is OK, maybe move a little to the left and the pan a few degrees to the right? It might also be a good idea to create another camera and set it up for a portrait shot just to see what that looks like.

nah dont use clipping planes, model the room bigger / push the walls back. much easier

 

as far as the burn i wouldnt worry, it looks like you have a pure white material so some burn is to be expected, get textures and glass on and it will be fine - then use camera to expose.

[Dave Buckley]

it is for a website to show what the rooms will look like in a proposed building.

 

i will post an update with th sun as you said to see what you think. i do prefer it with the sun,

 

as far as the clip goes, i will be photoshopping it but is there a way around it in vray???

[kippu]

i prefer the burn ....its good thing to have and just make the room bigger , you cannot notice it much anyway

[Dave Buckley]

ok guys i have lowered the sun, the default material at the minute is the defualt greay vray material. i know the update is full of noise. and the background image isn't great, what do you think to the sun angle and the bloom though

[Dave Buckley]

i'm at the point of putting glass in the windows guys, however, i have applied the 'window glass' material from vraymaterials.com to a box. it has made my scene a lot darker, i assume becuase my light is now passing through a box instead of free space (makes sense) do you guys advise adding the material to a plane instead of a box, or just re-adjust my exposure to suit???

 

i'm not sure how thick to make the box you see with it being double glazing, will it look more realistic if i put both glazing panels in?

[Dave Buckley]

heres the problem guys and its baffling me

 

attached is the render with the glass in the window (box with glass material applied) it appears that no sunlight is getting through the glass although the sun is in exactly the same position as it was in the previous render (no glass) however if no light is passing through the glass then how is my scene so well illuminated???

 

there is only sun/sky/physcam/plane light at window

 

Nothing has changed between renders apart from box with glass

 

its making the scene look really cold which i don't want and it now looks like an overcast day rather than sunny day
