CineRender Roof Standing Seam

[Brad Elliott]

Have a couple of days to start learning the new CineRender so I'll probably have a few of these.
I am trying to create a new Standing Seam Roof surface. When I look at it in the library it shows this nice standing seam in the middle of the rendering ball. When I select it the seam disappears and I get the round ball only and a flat roof in my rendering. How do I get the seams to show? When I select the corrugated roof that pattern remains as shown even though it is way too shiny.

Instead of using the displacement map, have you tried to use Roof Accessories to add the standing seam an render as usual. Normally that is what I have always done.

[Brad Elliott]

In the past I have had a hard time getting that to work right on more complex roofs but I'll give it a try.
As I mentioned earlier I wouldn't mind a close fake either. I don't understand why I can get a decent looking corrugated roof that renders in a reasonable time but not a standing seam which seems like it would be simpler.

Also did you tried using bump maps? They will give a reasonable "fake" to the roof.

See Karl's example here

Another option is to use the Roof Tool to create one standing seam, then Multiply. This allows accurate placement, and will show in elevations as well as 3D.

Karl's link uses the displacement button that sends my render time effectively to infinity. But does look great on a very small sample roof. If I could figure out how to make the bump map work I might be fine.
The standing seam roof accessory worked pretty well in my test and rendered quite nicely and quickly. I'll have to remember it. However a lot of these renders are during design when I'm moving roofs around so I'll have to delete and regenerate quickly.
I have realized part of my difficulty is that the fake lines show up in the Open GL view and are ok but disappear in the CineRender view.

Ummm... The roof surfacer should stay LINKED to the roof that generates it.. so making changes to the roof plane would follow thru to the surfacer piece(s)...

Yes?

[Brad Elliott]

I appreciate you guys hanging with me on this.
Yes, as long as both layers are on. If you hide the accessory layer, say to make the roof easier to work on or you want to see a different roof finish or your plan layer set doesn't have it turned on and you forget and make a change you lose the link. Over the course of the project in the past I have found that I loose the link a large percentage of the time.
But at least this gives me work arounds. But is this typical that adding the displacement on a relatively small roof turns a simple render in to an all day plus or in my case a crash inducing ordeal? Also does anyone else have a bug that the preparing process which can take seconds can also hang.
Is it reasonable that a very simple shell model renders in 14 minutes at Outdoor HDRI Fast does not render at medium or high?
It seems like several years ago before lightworks someone put up a standard model and people rendered it to see what a reasonable time was. Maybe we need to do that again.

[Eduardo Rolon]

For 90% of the time the Fast setting is the only one you need to use, provided that you turn on "Ambient Occlusion" 😉
Which I could tell were it is but then I would have to kill you.

This took about 10 min render time on a 2008 MacPro 8 Core while working on other AC projects.

[Eduardo Rolon]

and a white model were nobody misses the standing seams on the roofs.

[Brad Elliott]

OK fast with ambient occlusion is nice. Why is this not the pre-set? I don't know that I will look at anything else at this point.
As for white I really like the idea but this is what I get. Very moody which is not how I want my clients.
