Hi guys

I did a simple heavy test.

A cliend of mine gave me a 3d model modeled in Autocad and then renderized in XSI.

He gave me 16 obj parts with textures, unfortunately all polygons were random flipped and overlapped. I tried to convert all obj blocks with Deep Exploration…but not all polygons were converted to double side, I donno why.

From DE I exported the obj scene in Max then in Lumion with the dae exporter.

Then In Lumion I aligned all the 16 parts and changed some material. The terrain was modeled in XSI.

I added the water plane and some trees and objects.

At this link the video:

Many sequences were slowed in Premiere Pro, you will notice drop frames, it's better to slow with After Effects, it uses interpolation.

Attached here the stills.

 

My conclusions are:

Lumion is a fantastic tool but needs improvements:

- Clip speed affects birds and moving objets. I noticed that the clip speed effect sometime stops the flying birds of one frame. Check yourself.

- Clip cut in-out must be repaired

- Flicker problem: all videos generated by Lumion have flicker, in shadows, overlapped polygons, camera clipping, etc. Lumion staff has to find a solution

- Reflection maps has to be improved. Look that poor reflection on that large openings under the portico.

- When the camera pass orthogonal through the water plane the deep blue disappear in one frame.

- Impossible to drive a car on curves or inclined planes

- Impossible to attach two clips with the same camera position in the same place because on every clip there is a sort of dissolve effect, the luma changes. Check yourself. Is it an auto exposure effect? Is it possible to disable it?

BTW,

Lumion now is a good promise

Great test.

Critical note: the white is too white, its burning out too much. ( in your movie)

A little bit is natural by hard sun light. but its so much that make's your scene overexposured.

Picture 5 is a nice photo!

 

See these 3 test images.

It is the bloom slider by weather if you have turned on advanced mode.



Pic. 1 Bloom=0

Pic. 2 Bloom=0.5

Pic. 3 Bloom=0.7



Thanks for your post en note's! Laugh

Good work!

"Clip speed": This effect should not affect the animated objects ("Move Items" and people/animals). I have responded to your bug report yesterday, as well as amended the entry on the wish list so that users should be able to turn this on/off (Search for "Affect animated objects").

"Cut clip" effect: As I wrote to you yesterday, I have not been able to reproduce this problem. Please follow the instructions I have provided for you in the post where you have reported the problem.

Flicker problem: I replied to this request in the post where you originally reported it.

Reflection map: This is a known issue and has been discussed a number of times already. We have also registered this request on the wish list a while ago.

Water transition: I'll add a request for a better transition to the wish list, e.g. a fade effect.

Animated cars on slopes: This has also been discussed a number of times and the appropriate request was added to the wish list some days ago (after we made the wheels spin when moving cars).

Clips with the same camera perspective: I'll have to look into this.
IMPORTANT: Please do not send private messages and emails to members of staff - unless we specifically ask you to send us sensitive information, for example License Keys.

"Clip speed": Don't expect the feature to slow everything down soon.

Reflection map: You can set a new reflection point which solves some issues. We might add plane reflection at one point and maybe antialias some reflection at really big render speed penalty cost.

Water transition: The water transition is actually a really difficult issue to solve so don't expect this quickly. The only thing we might add is that you get a quick go underwater bump.

Animated cars on slopes: Currently not high on our priority list

Clips with the same camera tonemap: Tonemapping has a slow addapting to the current brightness. You will need to add a fadein to not see the effect.

Good work! But look at 3:20 of video. Here we see some problems of Lumion that are very important at my type of works. Very difficult task is to fit surface to the model of levelled road. So road junction decreases in the mountain and somewhere grass grows through asphalt.

Second, we can not grow wood on the big surface, so we have mountains thick with grass instead of trees and pitiful groups of trees instead of groves.

And for north or temperate climate areal there are no trees at all (except bad birch and unlike pines). No Maples, no Rowan, no Lindens (free or cutting), no Chestnuts, no Alders, no normal free or forest Firs and no Oaks that looks as oaks! How can I create scene with landscape of wood or park in or near town district without that trees? Put in palms and baobabs?
One might say that Lumion cuts off regions where they do not want to develop a market, but how about Canada and Alaska?

The different climate trees are more a time problem than that we don't want them.

Enough work ahead for us I would say :D I think you can agree with me that it's difficult to have content for every place on earth from day one. The current tree library is the Speedtree Library.

photoshop retouch

Levels and photo filter cooler?
Looks pretty!
Nice angle with the trees infront. The water also looks very nice.
You have your phantom yet?

waiting for the first Phantom, should arrive March 15
You measured the thickness of the board? Do you think is possible to assemble a 4 way GTX 580 in a EVGA SR2 motherboard?
I want to build a monster machine for 3 reasons: Vray RT, Lumion and Crysis 2... :-D

For the retouch I use Nik effects with selective color correction. The final png sequences will be retouched in After Effects.
The final animation will be stereoscopic too.

I had to place mine in my 2nd slot cause on slot1 it just couldnt fit :(
2-way will be possible for sure of course, it seems like a pretty sizeable MB so, if they designed it with some sense, perhaps it will fit...barely.
You gonna build your own nuclear reactor to supply it with power and cooling?   :-D

What's the rendertime of a single frame of this model atm?

Edit: I'll meassure the thickness of the board early this evening.

Hi guys,
one question, what are the minimum requirements and specs for a pc to use a phantom gtx 580 , 3gb??(motherboard, processor,etc) I am asking because I am about to build a brand new computer...... thanks in advance for your help!,,
