Debugged your Level-Of-Detail?

September 9, 2009

RenderVol-1I’m sure many of you already know about this issue, but I am also sure that many don’t. Since the release of Bax Prestige Boots, they have been blogged quite a few times. Thank you very much for that :). But in many of the Blog pictures that show Bax Prestige Boots, we recognized lines on them between the foot and calf part. Of course we immediately investigated on that, the result was that the pictures were taken with the camera moved away and then zooming in with ctrl+0, witch is  perfectly right. Though zooming in closely requires also to Debug your RenderVolumeLODFactor in your personal SL™ viewer settings. This issue is not new, but it seems that now it has become even more important, even with all settings on ULTRA you may experience that your sculpties are somehow borked, thanks to the default Level-Of-Detail settings. Sometimes less, sometimes more obvious. So we thought it definitely wouldn’t hurt to draw some attention on this matter, as it is a very common issue with an easy fix.


NOTE: After you increased you RenderVolumeLODFactor and you change your settings for example lower them for Model purposes the changes you made to RenderVolumeLODFactor are reverted to default settings witch is either at 1.00 or 2.00. This means after each change you make in your Graphics tab you have to also Debug LOD again for a flawless view. Same procedure when you update your viewer.

Debugging LOD

Debugging your LOD settings is something that will force all your sculpties to keep their correct shape. This is how to do it:

1. Show the “Advanced” menu with Ctrl-Alt-D, or Opt-Ctrl-D on a Mac (top bar of your viewer).
Select “debug settings” from the drop down menu (almost at the bottom).
3. A new small window will pop up.
4. In the blank space, copy and paste the word:


5. The preferences slider range sets this value between 0 and 2, set it to 4-5 here to get all your prims looking great. Then close the window.

NOTE: Unlike increasing your draw distance, this will NOT create much more lag for yourself or none for those around you! And it will improve the look of all objects.

  1. You know, I had done this in the past but didn’t know I had to always do it! Thanks so much for putting this back out there!

  2. ty VERY much Bax i had no idea and have been fiddling with my draw distance etc doh

  3. Actually something else you should fix is RenderMaxNodeSize was changed to a lower setting in the last viewer update you should have it at least to 6000

    by only changing only the LOD you may effect other sculpties from rendering

    but i do support taking the LOD to 4 at the least

  4. Thank you Kate for your input 🙂
    We tested through different “RenderMaxNodeSize” settings and it doesn’t really make much of a difference with higher LOD, unless you have a huge amount of sculpties in your view, then maybe some do not appear
