Sorry, missed your reply. I'm just curious how you're getting the metal on the screws and the plates to look so good. In terms of the brushed look, and what what spec/roughness you have, if you are using a fall off done etc.treddie wrote:I'm a fan of standalone apps.

Here are two jpg's showing how I handle white and anodized aluminum. Curious that using the published IOR for aluminum does not work very well. So I drop down to 1.0 to get the really metallic look.
The linear brushed metal texture is a snap to build that's been around forever...Just make a Photoshop file with a medium gray background, add noise, then do a motion blur on it. Do some Brightness & Contrast adjustment on it to get more of a white black effect. To get a smoother style look, I have actually built my streaks in Illustrator by hand, which is time consuming but looks great on the side of a cylinder. The only problem with using a brushed metal texture image is that it needs to be fairly high res to hold the scratch detail or it just goes to a smooth streaky look. But there is no other way to do it unless Octane would create a procedural for that one (which would be great and REALLY cut down on memory usage I would think).
Unfortunately, trying the same thing for a circular brushed metal look where you replace the motion blur with a radial blur does not work very well. So I built that one by hand as well in Illustrator with a bunch of random circular lines that do not complete full circles.
For something so simple to build, the effect is pretty awesome.
Oh, remember to use a normal map instead of a bump map. Bump can't hold the reflection angles very well. Getting from a grayscale-height Photoshop file to an RGB normal file is a snap with NVIDIA's free normal map filter for Photoshop.

That's great info. Thanks for the pointers. I've used them to create my own version, using procedural nodes. Not a circular one though 
Would welcome your comments.

That's awesome! If I break up meshes into tops & bottoms and sides, that will work great for a lot of stuff by just doing the basic texturing right in Octane. Thanks for sharing that!
If you look at the top of that big white aluminum plate, that one has a more complex brushed metal pattern...It is just a linear brushed metal duplicated as a separate layer on top of same and rotated to give a two-direction brush effect. That could easily be accomplished in Octane I would think with a Mix material using your procedural twice, one over the other with a slight rotation on one of them.
What procedural nodes did you use to get the effect?

Cheers. Messed with it a bit in Standalone, and on an object that looks a bit like part of yous. No UVs or anything or different surfaces. Think I got it looking a little better.
I don't know how to save materials in Standalone. How do I do that, and I'll upload the material for you to mess with. It actually seems to work as a circular one too (I discovered by accident)

That's REALLY nice!
Hehe...I haven't even tried saving materials yet and I've been an Octane user for a couple of years now! Attaching it as just an .ocs file would be fine.

Here you go.
It's very fiddly, and requires tweaking for almost every situation it seems
Hopefully you'll see how I've got a useful pattern out of the procedural node. But those settings change when you change the projection mode. Best way I've found to modify level of the effect is by altering the Gamma in the Correction Node.
Have at it though and hopefully you'll be able to get some practical use out of it.

Many thanks! I'll experiment with it. I'm really curious what will happen to my memory usage. I think it could be a perfect solution for most of the parts, but I will still have to break my meshes up...The direction of the scratches is different for different sides of the parts. I just wish Octane had visual tools to help figure out what the orientation is for the projectors, but I suppose that's down the road.
The Gamma makes sense, since it's sort of like a Brightness & Contrast adjust in PShop. I always make the brushed metal bitmap a little on the contrasty side to give sharper falloff to the scratches.
