architecture first interior scene...

[itschriswebb]

hello everybody. i'm giving this interior architectural visualisation stuff a go but have come across a few problems! this is what i've got so far...



i'm trying to get the shadows to stand out more. under the windows there is a ledge where you'd expect a shadow to be too. but its as bright as the rest of the floor! any ideas? below is the scene detail setup:

daylight system (only light), mental ray, final gather (draft at the moment) with 2 diffuse bounces, global illumination multiplier 0.8, logarithmic exposure control brightness 100, and the exterior daylight box ticked.

if any of that means anything to you give it a shot!!!

thanks!

It's a good start, with a few changes to the settings it will be a lot better though! First of all, with draft final gather you won't be seeing all the nice and detailed shadows you're expecting, it's fast to render but that's why it lacks detail, try setting it to medium, it should already be a lot better.

Furthermore you shouldn't tick the exterior daylight box, because it's not. You might need to set the diffuse bounces to 1 so it's not too bright and make some more adjustments but generally you don't want to use the exterior daylight when you have an interior scene.

Looking forward to more renders, don't forget to add some furniture to make it look more interesting!

Great start,

You could try assigning an Arch & Design material to your ledge, with Ambient Occlusion turned on, that might help alittle. And as Jelmer said, once your FG settings get better, so will all those small detailed areas (and render time)

I like the floor, it has solid potential. But you might want to play with the reflectivnes of the ceiling, I think its slightly to reflective.

hey guys. thanks for the useful suggestions. i have since fiddled with a lot of the light and shadow settings but with not much luck. it took a while by i have finally nailed the problem! it's im the material. i used an arch & design matte material i think and it was relfecting the light off of itself like crazy! have a look at the image below;



the walls are no longer bouncing the light off like before... i have left the ceiling as it was to show the difference. look at the irregular colouring and the lack of shadow!

And dont forget the reflection on the wall causing a reflection on the floor. Ahhh... the wonderful world of interior renderings.

Not too bad looking tho keep working on it =)

hey hey! right the house has completely changed! but i think i've made an improvement with it. it's by no means finished but i thought i'd throw it up for you to critique.



there are certain things i want to improve on but i'll let you spot those!

Looking really good Chris......really good.

Only 2 things stand out at the moment.....the corners between the ceiling and the walls looks, well, harsh. Difficult to describe but the two don't seem to be joined just because of the way it has rendered.

If the 'sun' you are using spills onto the upper surface of the ceiling, and the ceiling is just a plane then this can cause this effect. Strong light can and will 'bleed' through the corners....it's to do with the light illuminating the non-normal side of a poly. Easily solved though by adding some arbitary geometry to cover the outside, just another plane with the normals facing upward would do, just to deflect the spilled light.

This effect can also be caused by seperate objects, ie, the walls are one object and the ceiling another. Not knowing how you've created this I'm just trying to cover all the bases....LOL.

Apart from that and the fact the clocks wrong, (this is really nit-picking but check the hour hand position if the minute hand is nearly at half-past ), the rest looks great, and as you say, it's not even finished yet!

Regards.

thanks very much MrTom for the comments! have changed the clock now. funny because when i put that in there i thought to myself "i mustn't forget to change that"!

yes the ceiling does have issues. i have the feeling that what's happening is the black cornice board on top of the wall units and oven/fridge units is boucing black onto the ceiling. you can see that the ceiling is darker above these parts. not entirely sure how to solve this although i have to look at the black material anyway. i might also do a render with no bounces to see if that really is the problem.

[itschriswebb]

mmm now this is interesting. i tried turning the bounces down and got little difference with the dark ceiling. i have just rendered it without the kitchen and look what i still get!?!?

[MrTom]

LOL....no probs, the clock is just one of things that will give the game away!

As for the black 'bouncing' well I dunno about that. It's more likely that the ceiling isn't being illuminated because the 'black' does not reflect any light. Before you go changing materials try the top of the units with the same material as the ceiling........use 'Region Render' to just re-render that part of the scene....it'll be a lot quicker.

If you find the same thing happens then you can rule out the material, and maybe look into what's lighting that part of the scene.

Anyway, enough rambling.

Regards.
