Render times: Lumion 2.5 vs Lumion 3

hello,

I noticed that the time of export is longer between  2 and 5 times  with animations.

Is this normal?

In lumion 2.5, the export time was much shorter

Thank you so much.

Jonathan

Hi Jonathan, what do you mean by 'export time'.

Do you mean the time it takes to render a movie in Lumion 3 compared to the time it takes to render the same movie in Lumion 2.5?

Render times are a slightly longer in Lumion 3 but should definitely not be 2 to 5 times longer (unless you have added new effects such as the Reflection, Volume Clouds or Global Illumination effects in Lumion 3).

1) Can you post the exact render times per frame of this scene in Lumion 2.5 and Lumion 3 please?

2) It would also be useful if you could run "DXdiag" in the Windows Start menu -> Click on "Save All Information", and attach the dxdiag.txt document to your next post (Click on "+ Additional Options" below the text field). This allows us to check which graphics card, Windows version and hardware you are using.

3) If you would like me to investigate the render times on my PC, please export the full scene in .LS2 format in Lumion 2.5. Then zip + upload the file to wetransfer.com (my email address is morten [at] act-3d.com).

Thanks in advance.

Hi Jonathan, you sent me a scene saved in Lumion 3 which I can't open in Lumion 2.5.

In order to compare render times, I will need a scene made in Lumion 2.5 which I can also open in Lumion 3.

I'd be grateful if you could upload the scene in LS2 format (for Lumion 2) instead of LS3 format (Lumion 3).

By the way, I tried to load the LS3 file you sent me (375Mb).

Windows stopped responding while loading it, and I waited for 25 minutes before I lost my patience and had to restart my PC. In other words, your scene is too complex (and/or uses too many textures) for my PC and graphics card.

Please click on the i button in Settings. Then go to Build mode, zoom out so that most models in your scene are visible within the viewport, and let us know how many vertices ("Verts") your scene contains. A k means 1000, so as an example 6000k means 6,000,000 vertices.

I have been doing some tests just yesterday between v2.5 and v3 due to issues with my poor performing GPU or just whole system (just looking for excuse to upgrade to a nice GTX680  :-D ).

Seems on tests of sample scenes (Living Room with lights on) that v3 is actually a little faster even at 3 star than v2.5.  However once you add in GI and then on top of that reflection planes those 2 jump the render times per frame up from massively for example 25fps, 3star, no f/x Lu3 4 sec/frame, add in GI: 7.2 sec/frame add in 2 reflection planes 14 sec/frame.

Hey !

I found the cause to my problem
it comes from the lights and special effects
removing some lights that I made​​, I divided the time to export by 10, I assure you.

thank you very much

Nice to hear than, Jonathan :)

If anybody else experiences long render times after adding lights, please read the Tips, Tricks and Shortcuts thread (search for Light properties).
