Since I'm not sure what all the controls do.. I may have some totally wrong settings here, and it may well be the cause of my problem...

I was doing a fairly simple scene in Poser 8 to try out if IDL was faster or not. And also testing those new shadow samples.

But I got some annoying artifacts or shadows or whatever it is. And I have a feeling it's related to some setting I have wrong. Probably shadow bias or something. But I've tried with much higher and much lower settings in the shadow bias, and the artifacts remain. They've been worse than this, but I'd like to see them gone for good.

Here's the pic:

The arrow points at my problem. Ryan with Tomo Shiny texture, default Poser 8 hair. Poser primitives Stais with the Dull marble procedural shader on them. And the studio backdrop. One point light - and IDL.

Here's the render settings. They're probably hopeless...
 

 Hmm, I think some Mr. Clean and a mop and a rag could take care of those marks.

In 8.0, whichway and others were taking Irradiance Cache in the 99's. There was even talk about if it dropped below 99 and what the effects were.

However IDL was changed a bunch on 8.1, so I don't know if what they were saying is true any more and I have not tested enough yet. 

Uhhh. How shall I put this. I must be delicate.

You can't make that artifact go away. It's not an irradiance caching problem. It's not a Samples problem. It's not an Intensity or Bounces problem. It's a ... shhh ... bug.

It's fixed already - but the fix got done too late for SR1. It will be in SR2. I really wanted SM to postpone the SR1 release to get this fix in, but there were soooooo many people complaining and so many bugs were already fixed.

These artifacts appear where two surfaces meet in a corner at or near a right angle, and they change if you move the camera around.

For now, you'll have to touch those up with Photoshop.

So...when is SP 2 coming out?

pending the release of the fix, those occlusion errors near the intersection of two surfaces can be decreased if the two orthogonal surfaces are welded.   those occlusion errors also occur at the intersection of a sphere and a planar surface bisecting the sphere, which is harder to weld AFAIK.  as mentioned above, increasing sample number and decreasing sample size doesn't help in an example such as trekkie's first image.

Quote - So...when is SP 2 coming out?

it would be so funny if people would now start complaining that SR2 is not realesed.

he he .

I may of jumped the gun, I should have waited till people complained SP1 ruined their lives.

SP1 has ruined my life & I want SP2 NOW!!!!! only kidding! :b_grin:

 Heh ok. And here I thought that SR1 was the cure for all (well..except the decimal point L)

But in a way it was good to know that it wasn't because I was doing something stupid that they persisted. *And siunce each render took somewhere between 28 minutes and 1½ hour depending on settings (the original was wider than this one - it fit on my hdmi monitor) it became a little tedious to re-render this over and over just to see it this setting would help. Especially since I don't really know what the various settings does :)

And we'll get SR2 - and possibly SR3, all in good time. Remember Poser 7 wasn't really properly finished until SR3. I can wait as long as I know it is being worked on.

Looking back over my many render artifact bug reports, I think I got this one mixed up with another. It is not fixed yet, which is why it isn't in SR1. A different bug I found was fixed on the day after SR1 was packed and set up for distribution. However, I'm sure this one will be fixed for SR2 anyway.

Well, I, for one, can wait till all the bugs (well as much as humanly possible to get rid of) are fixed and Poser 8 is a stable version like Poser 7 was at the time of Poser 8 release... :lol:

If I look very close, and please correct me if wrong.

The front of the stairs is on the ground. Correct?
But the back is OFF the ground.
There is an opening between the stairs and the ground....
I can see light below the rear left bottom corner of the stairs.
I have seen this happening before if walls and floor where not exactly aligned. (gap closed)
Indeed, gluing or welding them together would get rid of this "opening", and "touch wood", the artefacts would, should, could, (be careful here) go away.

check and try it please.

**TrekkieGrrrl:
Are you using the mac version of poser 8?
I am asking because i like the menu you are showing for the rendersettigns.
(and mine looks completely different  using the windows version of poser 8, or did i miss something else :))

greetings

 Vilters: I think it's becaiuse the backdrop is a little uneven. The stairs are in their default flat position, I didn't move that on the Y axis at all.

And xuu4u - this is Windows. That enhanced Render menu is available through the Python scripts menu. Partners -Dimension3D -  RenderFirefly.

Much better than the default. I wish there was a way to substitute the normal one with this. Nine times out of ten I forget and just click Ctrl R...

Well, as a test I would "drop " the stairs a bit, to be sure to close the gap that is evident and clearly visilbe, and redo a test render.
(or move the backdrop up  a  bit, same thing)

Hi,

I'm getting exactly  the same artifacts on a skirting board running round the floor edge of a room, I tested by moving the floor up so that it's intersecting the skirting board, closing any possible gap that might be between them both and it still creates the artifacts, so it doesn't work for me. Also to add that (as said above) changing any of the settings doesn't make any difference either.

But, if SM are aware of it, as it seems they are, then I can wait for SR2.

I think I'll send them a picture anyway, just to be sure :)
