Repeatable bug for Soft Cloth Dynamics:

I think I know why Soft-Cloth dynamics needs an unacceptably large Collision Margin. It appears to be down to the greyscale values of the Weight Map applied to the objects. Here is an easy way to test it:

-Create a Floor and make it a Rigid Body
-Create a Sphere and make it a Soft Cloth
-Give the Sphere Self-Mesh Collision
-Give the Sphere Weight Map a solid Grey colour
-Drop the Sphere onto the Floor and note the gap between the Sphere and the Floor
-Adjust the solid Grey colour of the Weight Map attached to the Sphere
-Drop the Sphere again and check out the gap between the Sphere and Floor (it's changed)

In a nutshell, the greyscale value of the Weight Map is influencing the Collision Margin as well as how the dynamics are applied. Been playing with dynamics all day, trying out Cricky's suggestion (thank's Cricky) and just noticed it. As an additional note, Soft to Soft dynamics is soooooooo bad it might as well not exist, but I have a feeling it might have something to do with the Weight Map influencing the Collision Margin - so fingers crossed on that one!

I haven't read all the problems and hope I'm not repeating a bug or problem. I just finally got my computer working right after buying a new 8GB Video card, power supply, then a motherboard, upgrade to Win 7 Pro, to have 32GB of memory. It works like a charm now. Here's my problem, I loaded one Audio program, Cakewalk Sonar X3; and looped it for 2.5 hours to make sure it didn't freeze up like when I first got this R9 290X video card, before buying a new motherboard. The chipsets on this MB seem work with this card AMD doesn't want to tell you there is a problem with 290 video cards and 700 or 800 chipsets. You know, buy first then you'll have to buy a new MB or overclock the older chipsets if you are lucky that method works. I got about 20 minutes of working with Wordpad, before it froze sometimes. Anyway now I can be certain of a problem I mentioned on here that I'm certain of now. I closed Sonar, and loaded iC6.1; it loaded very slow. I loaded in a project, and the project started jumping frame rates, and was not running smooth. I rebooted the computer and only loaded iC6.1, it loaded faster and when I loaded the same project, it now ran normal. I do not remember this with iClone 3-5 that you needed to clean boot to run the program properly. Re-booting is not a problem, but I don't expect this when you have 16 or 32 GB of memory. Not a programming expert at all, but this will be the first Windows program I've probably encountered where you need a clean boot to function normally. Also no one seems to be answering why with the modify panels, I cannot right click to copy and paste values, I have to highlight and use the control, "c" and "v" keys? Have a great weekend.

OK, I don't know if there is a reward for the weirdest bug, but I believe the following is a good candidate:

This is a torus that is placed on a plane, both at [0,0,0]. The torus casts the usual shadow and then 3 additional "ghost" ones. You can move the torus underneath the plane, and the 3 ghost shadows will remain.

The only thing unusual about the scene is that the objects are  very large: the scale of both is "5000", so the camera is at quite a distance.

This is with the Shadow range set to "Auto". If you set it to "Manual" you don't get any shadows.

It's a very small project, so I'm attaching it here for verification.

@Job
I think that's down to the way Shadows work in iClone and the fact that you have it set to such a large scale. Don't quote me on this but I think Shadow Blur is created by casting multiple Shadows in slightly different positions and then blending them to make one softer-looking one.

It looks like due to the scale, your extra Shadows aren't lying on top of one another like they would with a small scale. I'm amazed the Shadows still look like that, I think they're supposed to work a bit different in DX11.

Hi,
There's a problem with your file Animagic. It has no extension. Therefore, it is not affiliated with any program. This is a zip file? IProject?

@Agonos: Thanks for trying. It is a ZIP file with an .iProject file in it. I just tried to download it, and it worked fine. I wonder why you don't see the extension? 

@pumeco: I found this problem when rendering an IC5 project, which has a large city in a desert.  In the beginning the camera moves towards the city following a car. I was rendering it in iClone 6 and suddenly noticed part of what turned out to be a huge shadow. I never had this in iClone 5.

EDIT: Here is a still from the scene which had the problem:

The unwanted shadow is in the lower left. It is actually independent of any blur settings.

+1 on that.
It really costs time to test, animate again, test, animate again and so on. Especially, if the collison of a char works strange and often how it wants and when it wants. Please check this system again. It appears really buggy!
And: Motion-plus animations are no more "auto-deletable". You get the message, that is linkend, and no chance to delete it. Only help and ok. Then you must delete it and then you can animate. That costs time!
And please, please check the engine! It has big problems with highpoly content. Daz is difficult to animate - anything bigger near to impossible. V5 "ate" all without serious problems. What for does v6 need all this power of the machine? It doesn´t seem to use it, really!

I was having a strange shadow artifact show up on a scene I was working on...

I had created a large wall to act like a land mass across a large body of water - I placed it as far away from the camera as possible, in fact it was right on the sky sphere itself ...spanning from left to right.....

for some reason the water and sky ( used a modified version of sky tool ) started reflecting spots of black that didn't exist on my prop....what was stranger was that one of the black spot reflections popped up in mid air and looked like it was refecting in the sky - but it wasn't , I had hidden the sky just to inspect, and the spot was still there .....it was the water reflection emitting it .... I played around with the settings and adjusting the water transparency was the only thing to soften it up.

The prop was beige, to imitate a sand mound across a lake / bay - but the reflection spots were pure black. it looked as if it was reflecting dark crevice shadows....which didn't exist on the prop.

Animagic : Watch this video. The option "auto" triple shadows. In "manuel" mode there is only one but only if we are close to the object. Still, the closer the object, the more we perceive that the shadow is cut. And the shadow of the object is cut when we move away :D

PS : Any resemblance to your scene, is not accidental ;)

Love to see an example Ricky!!!!;)
