I wondered if anyone else have had any trouble with imported objects disappearing in advanced animation. Basically, some of the objects just fly off and disappear when I try to animate the height. Its not all the time, but quite frequent. They do not disappear from the building mode, but are completely gone from within the animation. Only way to get them back is to delete and reinsert. Sometimes it seems moving the object sideways before adjusting height can affect whether the object decides to fly off, but mostly not.

Im running 3.0 on a GeForce Titan, so all navigation and everything else is smooth as silk, but I do have a huge model (1km x 300m - airport terminal) imported from Revit, with quite a lot of other imported components; if that would make any difference to why this might happen...

Appreciate any answers or experience with the same issue!

I sometimes have that, but that's due to fact I'm still using an old mouse that needs replacing as Lumion is getting excessive values for the mouse distance.

One thing that might fix is to adjust your mouse settings so everything is much slower, just to do the animation work.

Which version of 3 are you using; 3.x.x ?  The problem you are having used to be an issue with an earlier v2 for change position, but was fixed.

Thanks for quick reply!

I will try with your mouse trick. However, my mouse is not really producing any excessive values, rather the contrary actually; I have to run the mouse 3-5 times quick over the mouse pad just to get values of 10 meters. Also, the object doesn't disappear high up or far down, it just disappears completely from animation while still being in place in the building mode.
Feels more like the program somehow is not too fond of imported objects... :)

Running 3.0.1

Hi raske,

Perhaps the Titan is just tooooo fast  :-D

Anyway  :),  sometimes I notice if I just hold the mouse button down for a long enough period on the object icon, say 3 seconds, then do the mouse move it seems to help, as well as moving the mouse up or down very slowly at first.

The issue is not one previously reported so I think Lumion is happy with imported and other objects, even larger objects such as yours.

Rather than use the mouse, you can always use the position input values to alter height.

Hi raske

This is just a routine check as you do not seem to have any Lumion license(s) attached to your forum account. 

If you have a license or are working for a company with a valid license, I'd be grateful if you could forward the license or the company name/email address to info [at], so we can verify that everything is in order.

Thanks in advance.

TIP: If you are working for a company, you can use 1 license key for multiple staff members, as a way to get full access to the forum.  You get access to the Commercial Users Forum section, and we aim to provide faster support to users in that section.

All that you need to do is to ask the person who manages the license keys at your company to go to your Account settings and enter one of the license keys. You will then have full access to the forum.

NOTE also for information:  there is a Free version available for people to use and trial.  It's not time limited and provides all key features and functionality but with a reduced Library.  People are welcome to use this version to trial and learn how to use Lumion, provided our legal requirements are met.  All Free versions also have a watermark.
