Lumion Draw Distance

I've seen several Issues in the forum that sort of dance around my problem but that are never quite the same. A few screenshots from the scene are attached. (rendering out a 1080p HQ video has the same results as the screenshot) A Link to the rendered video can be provided through a private message if helpful.

I'm having a problem where the geometry in the scene is not showing up for the camera until it gets a certain distance away, similarly the shadow do not draw on part of the scene unil they are also nearly as close. |:( The shadow draw distance is not a huge deal, but I can't have geometry not showing up at all then popping up in the last second. The Scene is a sketchup DAE file and while geographically large, the file size is somewhat small 23mb. The Lumion File is about 22mb. The Computer does not seem to have any problem rendering out any of these files or animations, and at any given moment is providing about 50-59 fps. Turning on low memory mode does nothing except make everything run slower. (F9 is on)

Any suggestions on causes, solutions, workarounds, or anything of the like?
In this case, the only thing I can think of is to create a decal type texture before I export it into lumion, but having some shadows from the 3d text would be prefereable.  :-\

Computer Specs:
Xenon Quad core 3ghz
8gig Ram
Geforce GTX 680-4gig

Thanks.

Hi wraarchitects, regarding shadows, did you already adjust the Range slider in the Shadow effect?

Regarding the disappearing geometry (I'm guessing you're referring to the Farmersville logo?), did you adjust the Depth offset slider for the sign material?

If so, please read the HOW TO PREVENT SURFACES FROM FLICKERING section in this thread:

Morton, thanks for your response,
See below.

Hi wraarchitects, regarding shadows, did you already adjust the Range slider in the Shadows effect?
The only lighting source currently in the model is the "sun source" Is there a way to adjust the shadow range of it? I am aware of how to do this with placed lights but not the sun.

Regarding the disappearing geometry (I'm guessing you're referring to the Farmersville logo?), did you adjust the Depth offset slider for the sign material?
Yes, I am refering to the logo in this instances. The logo is modeled text that stands off from the surface a few inches, and there are no flickering issues, that has already been adjusted in this model.

(Yes, I described how in my post above)

The information in the Tips, Tricks and Shortcuts thread not only applies to flickering surfaces but also to surfaces that disappear as the camera moves away:

What is the Depth offset slider value for the logo material?

where is the shadow effect for the sun can you screen shot it?

Set it to -.3 instead of -.1 and it apears to have solved the logo from disapearing at distance.
Thanks for the help.

The Range slider in the Shadow effect only affects the sun. Spotlight shadows can be adjusted via Edit properties. There's more information here (search for 'light'):

I guess I was looking somewhere else.
That appears to have fixed the issues I was having.
Thanks Morten

I've had this problem before.  It's really not a Lumion issue, more just something that occurs in all 3D modeling programs.  The further away you are from objects that share a coplanar the more the objects will combine.  Sketchup is really bad with this, for example, if you have columns underneath a floor slab the further you zoom back the more the columns will begin to poke through the slab.

For 3D text in sketchup I make sure to do two things.  One, always have the component a few inches away from the surface it's attached too, and two, make the text a little thicker than it would actually be.  It looks a little odd up close, but since the movie never gets right up to the sign you'll never notice the difference.

Hope that helps, that's all always been my issue when objects "disappear".

I've noticed that before in various programs but never thought about it that way, thanks for the insight
