Interior. Feedback please?
show user profile  alexnomore
Hi everyone!

I am struggling with this interior scene and I would like to get some feedback.
Linear workflow is new to me, so please be patient.

I used an sunny hdr image in the exterior, a standard direct light with vray shadows, a standard light to get the volume effect (all excluded exept windows and outer wall). And of course the interior lights are on, which looks strange I am afraid, with vray spheres lights inside.

The rendering took about 5 hours in 3ghz i7 and 2ghz i5 distributed rendering.
I think it is a bit long, so I am giving you also my vray settings to check them out if you feel like.

My question has to do more with vray settings and post compositing than 3d max.

Thanks in advance. I will back to you after 12 hours or so.

Alex.

So I am not great at rendering, but from what I do know try this.

Adaptive DMC
1 min 8 max

GI
IM
Preset set to low
Hsph 80
Interp 60

Light Cache
1600
Scale - World

DMC Samp Noise I usually use .005

Set dynamic memory higher (depending on how much ram you got to play with)

Also make sure your lights are 24subd or higher

I could also be completely wrong and look like an idiot, so yeah... lol

Thats an excellent scene - lovely modelling and lighting.

The main issue you've got is the NOISE. I keep posting this link up, but it is MASSIVELY important if you want to get good results with Vray. Watch, listen, digest and repeat:

Turn off use DMC colour threshold, so you can adjust the antialiasing separately from the sampling of lights/glossy reflections etc. As redstar said, DMC sampler to 0.05. Light Cache is usually fine in "screen" scale but with a small room like this "world" is fine too. Minimum samples can be set to 2.

my personal whines:
The blue stuff in the ceiling could use some extra attention, right now It looks like some kind of stone texture out of proportion.
The wood in the ceiling looks too perfect, could use some large scale bumping and discoloration to age it a bit.
The lamps are way too powerful, especially noticeable on the one between the windows.
If the metal on the chairs and tables is supposed to be cast iron, it should be just a touch darker.
On the floor the tiny tiles(right?) could use a bit sharper bump definition. Also the way the tiles transition to the wooden floor looks a bit unrealistic, I'd expect a tiny uneven gap at least.
The curtain holding thingies have a very stiff shape, maybe if they folded a little and sank into the curtains more it would look more immersive.

Sudden unexpected bump map above the pillar.

Nice render.

curtains look like they've been sliced rather than gathered

With your environment, I would go about it a different way.

You can use the Vray sun and sky (daylight system) or you can us a vray dome light with an hdri.
by using the dome light in this way, you will get true shadows and colors from the hdr image.

Detail enhancement might be able to be unchecked. This makes the renderer switch into bruteforce mode on difficult areas, increasing render times.

for the DMC image sampler, I usually go with min-1 max 4-8 (depending on scene) This prevents extra sampling on large flat objects (walls)


You are not showing the Color mapping rollout. For linear workflow, This should be set with
Gamma=2.2
Affect background=checked
Don't Affect Colors = Checked
