LumenRT 2 Released
-
Livecubes are great, but for me hardly any clients would be able to run it nicely
However great for in-house virtual product showrooms... -
The quality looks really good
-- but the cinematography of the video made me seasick. 
Best,

Just downloaded the trial. Opened a model and exported to LumensRT - got a warning:
What I don't understand is how this model is large... it's to scale and it's just the building. How come that is too large surface area? I mean - Lumens is made to be a viz tool for architecture...
-
Hmm, that was the issue when I tried it first 18 months ago, I hoped that was an issue of the past, too bad as most of my archvis projects are now commercial and pretty large.

Also, the LumenRT 2 pre-processing time depends strongly on the total surface area of the model.
A warning will appear whenever you try to process models with a total surface area over 4,000
square meters (roughly 40,000 sqft) as the time required to process such models may become
prohibitive. For very large scenes, you should consider using the Auto-scale lighting feature (see
page 29).My model I test is just what you see in that screenshot - it's about 60x24m ...
-
Oh - surface area... ...but... this is a small model... only 25K faces... and this is too large?
Currently been processing for 23min...
-
One hour... cancelling... end of office day.

I think something like an export video feature (such as in Lumion) would be good, so you get the option of having a fixed flythrough that is a nice resolution & has AA etc.
Edit* also artificial lights
Edit again* also can it make me bacon sandwiches every morning and run my baths? just realised I'm asking for a bit too much possibly
-
I'll give this a try with my last project which was made for real-time using Unity 3D.
However before I would every be truly sold on LumenRT it would have to support web playback (WebGL without plugin) and the ability to freeze the real-time lighting such that the file can be played back on a normal PC instead of a super computer.

Thomthom, sounds like the option to Auto-scale lighting is not ticked. If you disable the Auto-scaling, LumenRT computes lighting at a very high definition, and if your model is large (in terms of surface area), this could take forever and generate enormous amounts of data.
The Auto-scale lighting option lets LumenRT automatically adapt the resolution of the lighting maps to the size of your mesh.Bottom line, make sure Auto-scale Lighting is enabled.
I hope that helps. Thanks for giving LumenRT a try

Hi Dizain,
You need to be logged in as the admin user for the machine to install LumenRT. It puts the .reg file in the All Users/Application Data/e-onsoftware folder

Hi Dburdick,
i'm admin user for the machine to install LumenRT...
All Users/Application Data/e-onsoftware folder is not created.
Thanks -

I had a go again with Auto-Scale enabled - still taking ages to process. Seems odd.
A model with four times as much faces ( ~100K ) processed much faster. It was also many times larger in size. -
That's weird indeed, Thomthom. Is it possible for you to share the model that takes so long to process?
-
No - not publicly. Privately I could. Email or dropbox?
Another thing - navigating a larger models is very difficult. The camera moves so very slow - hardly moved in some cases. On a smaller model, of a small house, it was ok.
-
What times should one expect for processing?
I dug up one of the smallest and simplest models I got. On Draft it went pretty quick - couple of minutes. But on Standard, with Auto-scale it takes so much longer. Granted it will, but it's going beyond what I'd expect. In this case the model has only ~8000 faces and currently the processing is at 45% @ 8min. The leap seem to be very big. I've not even thought of trying any of the higher qualities yet.
What kind of model does the time indicated refer to?
Any special preparation a model should be put through first? (Or am I just too impatient...?)I have a Quad 3Ghz, 12GB, Win7 64bit machine.

Hi Thomthom,
I bought LumenRT at its beginning and just upgraded to The version 2 a few days ago. I expected a lot of this version as I excluded lumenRT V1 of my workflow for many reasons, and time spend to export models is maybe the main one...Even if there's improvements in material edition and export and quality, I'm still confused about those export times...We have to consider that after the export, the model is ready to use for instant rendering. So export with LumenRT is equal to export+render in another software...maybe less. But for a software that claims to be realtime rendering, I'm still disappointed by this product. No offense to eon team that worked on LumenRT, but I think the message you try to associate to your product is wrong, even more today where Instant rendering engines are blossoming everywhere...I'm pretty sure that if I spent a few more hours learning It, I'll take more advantage of LumenRT, but I'm still not convinced of your realtime thing !
Quality is here, really better than in the first version, but I'm still waiting for realtime.
Best regards.
Edit : Mys specs : INTEL EXTREME QUAD 3ghz, 8G of ram, WIN 7 64 Bits, GEFORCE GTX 580.

77% @ ~25min for the ~8000 face model.

Panga, yes, you are right that LumenRT "export" includes the physical simulation of all the lighting in the model. Obviously, if this simulation is accurate, it is going to take time; But once it is done, you can view your model from any angle, in real-time, with full physical lighting quality.
We'd love to be able to do this lighting simulation in real-time, but physical accuracy does come at a premium. If you are not willing to wait, you could always fall back to the lower quality modes.
Best regards
