Just came across from cgarchitect.com and found this info , I think this program has a potential as a new contender for lumion even thought they are still in alpha stage right now, check their website at :

Oops! ii was wrong section here, I supposed to put it on general discussion. Admin would you mind to move this topic there?

(ADMIN: Merged this post from a separate thread)

Has anyone seen this?

Looks promising............

It's a program made with unity. They use the runtime fbx import feature to load the model and then you can assign materials and add lights. Looks quite good, I think the spot light are more or less similar to Lumion. The rest is missing though. Another thing you can't see directly is that the fbx workflow is broken. They import from revit but from revit all materials are encrypted so you will end up with a white model. That's why we created the special exporter. I think the idea is to quickly have a walk through while Lumion is a program to quickly make movies.

Yes, you are right. For the present moment. But they work hard. And agree that their instruments to tune light more precise and more easy then Lumion's.

By the way.. We're working on the new quest3d5 and with it comes a reference project which is similar to this application. The good part is it't open source so people can customize it. You can import objects and fly trough them. If someone publishes this project from quest3d you basically have a free walktrough creation tool :)

It supports dae and fbx out of the box and we're currently figuring out if we can release the framework with deferred shading so you can add lights and have really good materials. That would be awesome!

Program looks nice, seems to have a good material system, exe-web publishing.
Major thing that's missing is Content. That's what makes Lumion so powerfull in my opinion.
Drop in a model, put in trees, cars people and you got yourself a nice visualization in a couple of minutes. Sure there is room for improvement (reflections, materials, publishing) but at this moment Lumion is still the best choice.

I agree. If you now count just the plants (even without the extra plugin); to get such a pack of 3D plants to use in another rendering software, you would pay about as much as Lumion costs. And then we have not talked about the LOD engine for them.

In what regard actually? From what I could see there are the exact same settings for a light. There's color, range, cone and angle. The only difference I saw is the abilitly to fade shadows in and out.

I think we can improve the point light GUI. With that I mean that the lights switch to a point light when you go beyond 180 degrees. A better approach would be to split each effect and assign it to a slider. So in theory we could have the following sliders:

Basic controls:
1. Colorpicker
2. Cone angle (in degrees)
3. Light Type (fades between a spot light and an omni light)
4. Photometric profile (IES)

Advanced controls:
1. Shadow depth
2. Indirect shadows amount (which is ssoa)
3. Transmission (how much it ignores the surface normal)
4. Shadow cache
5. Specular amount
6. Show/Hide light fixture
7. Range

This would give you the ability to define almost any light. We can add other light types later like an area light or line light.

One important addition would be the ability to switch or even load IES profiles for an already existing light. With that we would probably also have the possibility to change flag textures because in essence another IES profile is nothing else than selecting a new textrure. So if we could make someting to replace textures on objects in the content library that would be awesome.

Remko: all IES lights are basically the same, they are all text files. What distinguishes them from each other is manufactures text information encapsulated in [ ] brackets. meaning that there should be no reason for Vray IES lights produced in Vray for SketchUp not to work in Lumion.   :)

yes I know because we made a IES loader but right now it does not work on all IES files. A simple IES file contains only the intensity for each angle. This is perfect for 90% of the lights. More complex lights have an assymetric photometric graph so we need a bit more work to support those. Normal spot lights work perfectly though. I hope we can someday offer the option to load your own IES profiles in Lumion.
