New Interior Render

[JakeMM]

While I'm still improving my external render from the other thread, I thought I'd give an interior render a go.

This was saved as an HDR and then Tone Mapped in Photoshop.

On the whole, I'm really pleased with it. There's just a few small issues I've got;

1) What preset should I use for fabric? (I'm currently not using any)

2) The cushions seem to have picked up some green pixels and I'm not sure why that is?

3) The ceiling and picture on the back wall seem to have become quite blotchy, how do I fix this? (The frame is a piece of glass over a picture, the ceiling and walls were set satin paint. I've changed the ceiling to semi gloss but so far, it looks to be quite similar - it's currently rendering again).

Any other tips or improvements you can suggest?

Thanks Jake

It's great, but the floor looks too rough and too shiny for its roughness.

I agree the bump on the floor is too strong.

The couch cushions must be smoothed in SketchUp and then grouped or turned into a component. Then they will render properly.
Check some of the already-made render scenes in the Resources Master List for settings for furniture and other materials.

Thanks for the replies.

I think the issues with the floor were how I tone mapped the image and not necessarily how I set it up in Twilight.

This is how a JPG looks straight from Twilight (although I've changed a few parts from the last version). I used an HDR to bring back some of the brightness, as the scene is quite dark. I'm guessing however that I should probably just increase the power of the main light and probably change it from a spot light to an omni light?

How should I correctly setup a photo frame? I've modelled a frame and kept a small gap between the picture and the glass. I've kept the glass as purely one face, but set it at realistic glass. Is this the correct glass to use in this scenario and should I add a thickness to it?

I've changed the central light in the room to a Point light and it has now given the scene enough light when exported as a jpg (no post pro).

I still can't work out what is causing the circle light blotches over the ceiling and photo frame. Any ideas as to what could be causing it? I've found that the issue doesn't occur on Easy02, but does on Easy07.

Hi, let me remind you that this kind of lamp shades let light go upwards too. Point lights or IES files will do the trick.

Easy 07 has some higher caustics settings, while Easy 02 has none. My guess is that the caustics settings are causing the "circles"... meaning that actually the caustics quality is too low and should either be cranked up significantly or caustics turned off. I would choose to turn them off in this scene. So create your own render setting copy of Easy 07 and go in and turn off caustics. If you need help, let us know.

This lamp shade is mostly closed at the top, however I have changed the lights within them to point lights, which has evened up the spread of light coming out of them.

How do I create my own rendering setting?

Here's my latest and hopefully final version of this image. I decided to use Easy 09 for this version.

Wow, great evolution. Now it's getting close to a real life picture I love what you did with the pillows, they look excelent.

Very nice, Jake!
