small mesh object vanishes when camera is close

[Rhys Goode]

I made myself a small disk, about 4 cm diameter, 3 mm thick.  When I look at it in world, I cant get a real closeup view, it just disappears if I get the camera too close.

What's going on?  is this a feature that I did not know about?

Thanks!

It's the camera cutoff... sometime in the past LL has made a change that moved the render cut-off a fair bit in front of the avi. I've noticed that myself but never found a way to fix it.

Yeah, you would think that sometime in the last five years, I would have noticed it.  Behaves just the same for a vanilla flavored prim cube as for my little sculptie.

It's a relatively new change... I don't know exactly when that changed, but it was somewhere between the release of v2 and now. Not longer than a year ago.

The word you're looking for is nearclip.

Every camera in a 3D simulation has a nearclip and a farclip.  Anything in between the two will be visible.  Anything outside them won't be.

In SL, we can control the farclip, via the draw distance slider.   Unfortunately, there's no way to control the nearclip.  It's a very annoying omission from graphics preferences.

Camera near clipping has been in SL since I started 5.5 years ago.  Find the oldest viewer you can, and use CTRL-ALT camera movement to put the camera just behind the avatar's head, and part of the head will disappear.  Experimentally it appears to be set to 0.2 meters or so.

NearClip (thanks for the term, Chosen) is a fact of 3D rendering. However, the value/distance has most definitely changed. It's now further out than it used to be.
