Interior daylighting

[akinlolu olugboji]

First shot at interior daylighting since AR3, 60 passes and still going, will those dining chairs ever resolve? Being at it for two hours now. Latest build, default light settings except for the colour tone down to 0.5.

Any pointers at this stage is highly welcomed.

Looks really good, actually.  Send the chair material and I'll have a look.  60 passes is not very much for interior daylighting.

Here it is.

The curtails are another issue

Sky as HDRI and tagged curtails as daylight portal and thin (really it is a solid) and light links in. At 70 passes.

The chrome should be just a straight, shiny metal.  Using angular blend here is unnecessary work and may be causing some problems.  Curtain material is ok-- doesn't hurt to tag it as a daylight source unless autodaylighting is off.  Check your refractive bounces-- you may not be getting all the way out the window.

After 128 passes this(lounge 2)  is what I came up with but looking forward to achieving some thing like this(living_room_by_diegoreales-d3eg9tu). So I added the striped down autocad for kind folks out there to help set up the lighting.

Don't use HDRI with interior renderings. Sun and daylight will be quicker to resolve and give you a better result.

Tag window glass as daylight source, not curtains.

As Roy said, try to keep your materials simple.

If you're using daylight only, you may need to increase the number of indirect bounces.

If you're using daylight only, you may need to increase the number of indirect bounces. To what amount do I increase the indirect bounces?

[Peter Milner]

One immediate thing I notice with the model is that your viewpoint is from outside the building looking in through the window.

You need to move inside the room.

With flat materials such as emulsion paint and vinyl wallpaper, add a bit of glossiness using the glossy shader.

Very few materials show perfect reflections, so I would suggest you turn down the reflection sharpness on your floor and wood materials.

Make window glass perfectly clear and perfectly reflective. Model it as a region and tag it as thin.

For the curtain material, I would forget all the masking etc. Just give it a tiny bit of transparency and a lot of blurriness.

I'll post a render and updated model in a short while.

Great tips to have in mind in the future, Peter. A big thanks from me!

[akinlolu olugboji]

Thanks looking forward to it.

A couple of other things:

The architrave round the edge of the ceiling doesn't fit properly.

The skirting round the edge of the floor is partially enclosed in the wall and has the same material as the floor.

The glass in the double doors isn't tagged as a daylight source.

I'm not sure why there are odd reflections round the edges of the floor. I'll see If I can track it down.
