Good day.
While practicing on the bottle tutorial > http://moi3d.com/forum/messages.php?webtag=MOI&msg=4439.1

I came at 3 problems which I cannot fix and or understand.

1. Attached a pic of some artifacts after lofting the shapes. How can I get this smooth so these will not show up if I want to render this?

2. In the tutorial where the cap is being made of star shapes it is not straight it is tapered but with a curve.
the way I made is with 4 star shapes with different sizes and then loft. Is there a better way of doing this? this is not shown in the tutorial.

3. On the cap where it changes shape from star shaped to circle I could not get a smooth transition either. Loft will end up too sharp.

How can I accomplish these?

Thank you!

3. seems the Blend Tool works fine!
(don't forget to erase before the "curves linked" for have only "edges")



For the Top :
(don't forget to erase before the "curves linked" for have only "edges")
Move first the top cap for a more easy selection of the "Edges" make the Blend again
then move down the Top Cap as you want! ;)

I had trouble with blend ..as I always do..

What I was trying to do is to select all the pieces of the star shape join them together and then blend to the circle ...which end up in calculation failed.

When I tried without joining them together it worked.

on the cap with curve I made a new one with 3 pieces this time > loft > scaled the middle one.

Now only the artifacts needs improvement.

Thank you!

Hi Matadem, the artifacts you were noticing here:




are just artifacts in the real-time viewport display where there happened to be not quite enough triangles generated
in some areas.

You don't need to do anything about those artifacts, just ignore them. They are just a display glitch and not a problem
in your actual model structure.

When you go to export to render your model just generate enough density in the output and you won't have those:



It doesn't even have to be cranked up too much at export time - the display mesher and export mesher are different
the display mesher is heavily focused on being fast and takes shortcuts in various areas. The export mesher does a
more thorough job and is tuned for quality over speed.


If you want to have a quick check for this type of thing, set up a shortcut key with this as the command part of the shortcut key:
SaveAs c:\test.obj

Then when you push that shortcut key you'll go directly into a mesh export without needing to enter in a filename
and you can do a quick check with a higher density mesh. Then cancel the export.

Got it!

Thank you!
