Problem with 3D sphere in Photoshop Extended CS6

Jul 10, 2012 12:40 PM

Tags: #cs6 #3d_objects #cs6-3d #photoshop_extended_cs6

Here is a still from what will be a trade show video. The problem is that the longitudinal lines are a bit wobbly, especially near the poles, for instance in the top right quadrant, between the orange and yellow earplugs.

I created a new 3D object with the preset sphere from a layer that is a grid of my client's products.  As the sphere rotates, the black edges of the grid straighten out as they come around to the front, and then get wobbly again as they approach the edge of the sphere. At first, I made the black part of the grid from a bitmap mask (which had caused a problem in an earlier 3D file) but no, same problem when I made the grid from a vector mask.

 

Pretty sure it is not a hardware issue as I have gone thru all the optimization steps for using the Mercury Graphics Engine on my quad-core iMac 27" with a supported video card, and the latest version of OSX.

 

Can anyone tell me what I might be doing wrong?

 

Thanks!

    That looks like a possible "scalloping" bug that could be related to the one being discussed here:  http://forums.adobe.com/message/4460728

     

    It seemed to me that with relatively large objects curved lines between mesh points were being curved the wrong way, as though someone got a sign backwards in the software.  Adobe is working on it, but there's no sign of a 13.0.1 update so far.

     

    Not sure if this is the same issue at all, but it did trigger my memory of talking about it about a month ago.

    Hi Carol,

     

    I think you are seeing a limitation of that Sphere mesh preset. I sent you an email note for a download link to another preset that hopefully will work better. You can just replace the existing preset with the other one, or rename one of them so you have each to use.

     

    The thread that Noel brought up is a separate issue. It only happens with extrusions, and not existing presets.

     

    regards,

    steve

    Thanks, Noel. That was not the issue this time, but I was pulling my hair out over that one last week! I was trying to make an extrusion from a bitmapped selection, then I realized I could make it from the path I already had--world of difference!

    Steve, much better! Still a tiny bit wobbly, but MUCH better! Don't know how well you can see it in this little pic. I'll put it at Flickr, too.

     

    I have spent a very intensive month teaching myself 3D and video editing In Ps CS6. It seems it is so new, there is not much info out there, so I am really glad I stumbled across this forum--VERY helpful! Thanks!
