hi, while rendering animation.. i accidentally minimize the Lumion application.  After restoring the application, the screen suddenly become white. Lumion is still responding though.

Any solution for this problem?

Hi Bogz, that's a known issue - the exposure in Lumion is being reset when you minimise the window.

However, if your version of Lumion supports background rendering, you can use other applications while it's rendering without any side-effects.

There's more information in the Tips, Tricks and Shortcuts thread (Search for "Background rendering"):

If the screen is white when you start up Lumion it sounds like your graphics card isn't powerful enough for Lumion.

Did you compare your hardware with the minimum requirements?

Rendering a large sceen with LOTS of trees, water and 1024 textures...

I'm getting a Lumion white screen while rendering still images... (was in and out during the rendering of a movie last night).

It's just the Lumion window and not the entire monitor screen... AND the images and movies are rendering, but I'm wondering if something is not running correctly?

I'm running the newest GTX 680TI gpu, but my machine has a slower rated processor - could that be the problem?

Or what else could it be

It does that sometimes for my GTX 660 with a basic i5-3570 CPU, mainly when first starting the render, then after a little while the screen redraws when Windows has some free resources to refresh the screen.  CPU could be a bit of a bottleneck. For mine I know it is not the motherboard.

Are you running any other apps at same time?  Does it do it for the scene if you try a render from a clean re-boot of the system.  Are there many other background and start-up tasks being run at same time?  Sometimes pays to get rid of lots of (unneeded) start-ups.

How many trees (approx. will do)?

LOTS of trees... 1000+  they will utilize LOD in the far background right??  lower poly count on the ones in the way back?!

I have lots of geometry in the scene although it's not usually being rendered... will I save render time by turning off layers that are not being rendered?  That sounds silly but does Lumion need to calculate all the geometry that's NOT being rendered?

Thanks!
jimmy

Any recent movie making tutorials on the web??

Cheers!

Trees do use some LOD.  But also depends if you have F9 on or off.

Layers could help.  It will calc the whole scene, although for final render it's only the camera frustum that's used.  Certainly for something like lights it is definitely useful to have in layers and turn off. 

If you definitely know some geometry is not in or going to be within the camera view then placing in a layer so hidden would affect render time, but by how much I don't know.  Probably not that much, things like drawcalls from having too many little textures have more impact, but if the object is complex with lots of texturing then it may be worth exploring us of layer (if you have enough, max 20).

Are you still getting the white?

But if I have F9 off the trees still render high res?  ... and jst don't show on the monitor??

Only using one light right now... the sun.

Yeah, will render next round using layers on/off

Are you still getting the white?

Yes... just ordered new 8 core processor

  ? 680Ti or 780Ti?

780Ti

(Trees and plants are always rendered in the highest level of detail. In Movie preview and in Build mode, low/medium/high level of detail versions are used - unless F9 is turned on)

ok, that's what I thought.

btw - approx 4000 trees in that particular resort area... more in other areas

38.1 million points last i checked

Hi claricampa

Your post has been spit to a new topic, see Overbright Scene and Renders

Hi jimmy

Just a follow-up on your earlier post, has the white screen been resolved or still happening?

Hi jimmy

ongoing... could be maxing out the GPU and CPU maybe.

Still renders fine.
