Everytime I make a sphere, even if I restart illustrator and make a new document, I get that ugly dark spot in my image. I don't know what the heck it is!
I've tried everything I could think of to get rid of it, but I can't seem to.
The way I made the shere was by taking an elipse, making it into a perfect circle and then using the scissor tool to make it into a half-circle, then using the Effect>3D>Revolve Menu option to generate a sphere.
What is wrong here?
I followed just for fun this tutorial:
Everything works as expected, but I'm using CS2.
Plastic shading (default) works as well, but looks ugly.

Not sure, but there might be something wrong with your construction method.
Have you tried constructing your half circle another way?
Draw a circle using the Ellipse tool with Shift held down.
Then direct select and delete the left-hand anchor. No need for scissors.
I know what ius causing this and how to fix it but I am surprised you haven't figured it out because you would have had to deliberately added a new fill and use the Effect>Convert to Shape>Ellipse somewhere in the recent past.
First go the appearance panel from the fllyout menu check New Art Has Basic Appearance. Then stay with the Appearance panel select the that you have the 3D revolved applied to andd delee the top fill. Tou definitely have two fills applied and the top one has the Effect>Convert to Shape>Ellipse applied to it. Otherwsie this would not happen.
With the top fill deleted
That's not it. See my included screenshot, my appearances panel contains none of that.
Could it have anything to do with size? I'm working with a 2000pt diameter sphere (I do require that size though).
What the heck have these two examples in #3 common with a
rendered sphere (plastic or diffuse rendering)?
That's just graphical nonsens, in my humble opinion.

They are 3D shpere renedered in Illustrator that s what they have in common!
To the OP please select your object and then show your appearance panel while the object is still selected.
It would bee hard to tell what your appearance for the object is if it is not selected
Like such see the pth is selected that shows the actual appearance of the object.
Do you undersand now Gernot?
You clearly have the 3D Effect applied to the layer and not to the contents of the layer.
look a little deeper and you will see the problem click on the contents whie the object is selected and see what you have there.
Nictra Savios, others,
This may be irrelevant, but the black spot is a bit irregular and off centre; the highlight is also irregular, and there is a blue square a distance to the right from the centre (inside the edge of the highlight (lower right)).
The effect being applied to the layer or to the path itself makes absoluely no difference in this case. I have tried it multiple times, in many configurations. One of which was applying to the layer itself (Which is where that shot came from) while the rest were on the path.
Needless to say, the effect remains the same.
To the rest,
Did anyone try and repilcate it at the same size I did? 2000pt by 2000 pt on a 2048 by 2048 artboard.
Yes, using your dimensions I get the same result. CS5 Mac 10.6.8.
Edit: The phenomenon kicks in at 1866 pt.
Edit: Except when it's a higher value than that. The shape of the spot varies. Spot grows toward a circle as diameter increases.
I got the same behavior on Windows with CS5. Changing the perspective to anything but 0 fixes the problem.
edit: In dedicated 3D programs this happens when the size of the object extends beyond the camera position (point of view) which location becomes inside the object. The weird spot is a cross section of the object with the plane of the camera.
I want to see a screenshot of the object slected and the contents of the olayer visible in the Appearance panel, I say you havce another effect applied at the object level and not at the layer level.
It kicks in at 1866 pts Really in orderr to get something the size of the OP's screen shot it would have to be something like 60 Inches.
I say hey have another effect applied.
If not then they haven't told us much and it seems odd that they showed us in the OP the 3D window without the preview checked and the Appearance panel with out a selection.
Then they show us a sscreen with it selected but only show us the effect applied to the layer but not what is applied to the object and then the reponse to you query is evasive.
So I have doubts about this if you can see my point.
Let them post the dimensions along with everything else and then we can see what is causing this rather than hide the info we need.
Thank you Emil! you solved my problem, but what an odd work around. I wonder why this happens, is it some sort of limitation? If so, do you know where I could find information to help me understand it?
I did state I was using a large image in my very first comment, I am sorry you are unable to read. But then again, maybe you just didn't see it? It wouldn't be unreasonable considering throughout this entire discussion you have accused me of hiding information, offered idiotic solutions and demands that did not solve the problem at all and only made me sure that you have no clue how illustrator works on a non-superficial level.
Any Illustrator user worth their weight in vectors can tell you that applying it to a layer applies to across all objects in that layer (meaningless when there is only one object).
You told me what I should do for you because you were unable to diagnose a problem that somebody else could, using the same information, since they knew what they were doing and actually replicated the steps I stated and did not try to replicate the result without using the same method and then go on to crtisize me that I was doing something which I never once stated I did anything close to!
Furthemore, your tone of discussing and additon of useless information is unsavoury and very troll like. I would like to ask you to please, do not comment on my thread and get an attitude check as well as toning down your ego before posting on other's threads.
I got distracted by Gernot's comments and did not notice the 2000 pt dimension.
I believe this is a known issue, however even if you pointed out that you need a 2000 pt size I think your first comment made me think this was not just this time but all the time regardless of what size you use.
So true I could have read it better but perhaps you could have clarified it as well.
You will find on the forum that some of the contributers relate to soem posters and not to tohers this goes for the two that were able to asisst you as well, it is just a question of how each individual understands the others.
I often relate to users that the other two do not and vice verse. Just the nature of the internet.
And thaat does lead me to the same conclusion it leads you too I would be of little assistance to you as I will probably always read your posting in a different way that you intend it to be read.
No doubt in my opinion that you are correct avbout this I will definitely not comment on your postings regardless of the nature of it. I will post to threads tht are not posted by you even if your are contributing.
All the best to you
