Loft Bedroom WIP

Floor looks way too glossy but this could be a killer scene! Have I seen this rendered somewhere else before? I'm sure I've seen this model before, but maybe i'm wrong.

There's a roughness setting that controls glossiness

Here's a quick video covering some setup for polished floors.

And a couple new stills with fixed wood grain and reduced floor polish. Thanks for the feedback.

wow Adam, that looks really great! Those controls are quite comprehensive.

Nice work. Like the video too. I have one question on this render. the ceiling appears to be floating above the trusses, and this appears more pronounced on a couple "boards". What's causing that?

@peter

Are you referring to the back left corner where the ambient occlusion is more pronounced in two areas.

[pbacot]

The (AO?) shading of the ceiling at most of the trusses makes it look like it is floating an inch above the trusses instead of sitting on them. See the second truss in. Maybe it is the lack of the same AO on the trusses themselves.

I used the floor plugin to build the timber siding but SketchUp appears to have eaten a triangle there.

One thing is that raytracers tend to have quite aggressive AO cutoff by default - a few inches away from the surface and its full white - whereas LightUp defaults to a few feet.
Using the Custom cutoff distance, you get quite different results. These AO with no color bleed ('clay render') using increasingly large cutoff distances:

Adam,

Thanks for the demos. I am not sure what the answer would be as to whether I'd like the results in Lightup. I have to try it again. It looks to me like the AO is too pronounced.

Peter, the amount of AO is controllable by a Multiplier, so you can tone it down, change the blend colors, change the blending with direct lights. Lots of control to get the look you want.

I turned it up to full whack just so you could see the difference of AO cutoff.
