Weird wavy lines and streaks
Weird wavy lines and streaks
Attached is a crop of an outdoor/night scene I am working on.
If you look at the entrance doors, the aluminum mullions are all wavy looking, and there looks like an overlay of some sort of little lines instead of noise.
Hopefully this makes some sense when you look at the pic, most noticeable in the wall and the car.
But it is throughout the whole image, and all the mullions are wavy like that. The material is the Aluminum preset in Skindigo.
Any ideas?

thanks Suvakas-
the scene is 2000x1000.
I did this scene before, daylight scene, and it had the wavy line things at the mullions, but not the streaky things covering the whole image.
I am using the "Thin Glass" preset that Whaat came up with, maybe it's just weird reflections or something.
On another note, there is something really satisfying about making a cars headlights!

pixels-
it's how the camera is set up in skindigo, not sure about other programs.
I was hoping to get a good exponent map on the asphalt to get some of those little highlights, but no luck. just a render for fun anyways.
the streetlights aren't near powerful enough though. and I'm using a night time exr map, but it isn't coming through at all.
oh well.

I meant like how high/wide is your building in Sketchup? In meters for example?
Here's the link to the thread i was talking about.

Check the image Whaat has posted. Some strange AA issues there too. But then again..not very similar to what you have.

crc,
I have had the wavy lines problem too. See the golden gate bridge render in this post: http://www.indigorenderer.com/joomla/fo ... c&start=15
I don't see how it would be caused by Sketchup or SkIndigo, though. If you reading this, Ono, do you have any idea what would cause this??
You should be able to see your EXR map if you keep increasing the gain.
@suvakas: Obviously, crc is referring to the image dimensions, not the scene scale. I would guess that his model is drawn to real-world scale unless it was imported from another app.

Yep, that's the same thing.Whaat wrote:crc,

Increase the gain in Violet? OR? not sure if I know where to do that.Whaat wrote:You should be able to see your EXR map if you keep increasing the gain.
oops, yes, drawn to real-world scale.Whaat wrote: @suvakas: Obviously, crc is referring to the image dimensions, not the scene scale. I would guess that his model is drawn to real-world scale unless it was imported from another app.
Whaat -have you ever modeled a scene, than scaled it down? Hadn't thought of that before, maybe faster render times?
You can increase the gain in Sketchup in the 'Set Environment Map' dialog.crc wrote: Increase the gain in Violet? OR? not sure if I know where to do that.
I have never tried this because, I believe, it would not make a difference.Whaat -have you ever modeled a scene, than scaled it down? Hadn't thought of that before, maybe faster render times?
Re: Weird wavy lines and streaks
Are you using v0.8? if so the artifact could be caused by RQMC used in v0.8. Try v0.7 and see if the same artifact appears.crc wrote:Attached is a crop of an outdoor/night scene I am working on.
