Loading lights from multiple scenes

I'm working on a 3d app that is split between multiple scenes. I have a single master scene that contains common objects like the camera object, and several environment scenes that each contain their own lights. In my app I'm loading the master scene with scenes.load() first, and then loading one of the environment scenes. The trouble I'm having is that the b4w runtime isn't loading the lights from any scenes loaded after the initial scene. Is it possible to load the lights from my environment scenes?

If you have a look at the Cartoon Interior example project in your SDK, it loads a number of items dynamically. These have lights. The blend files can be found in blend4web_sdk/blender/tutorials/cartoon_interior/



*Edit*
After doing some checking, these loaded lights don't seem to effect the scene.

Actually, lamps cannot be loaded dynamically. The only solution is to have them all in the initial scene and turn on/off at a proper time by using the set_light_energy or hide_object/show_object methods.

Good to know Ivan, thanks.

Pedwards, if you want to try what Ivan suggested, here is a post about hiding and showing lights using logic nodes with examples you can download.

Thanks a lot for your answers guys!

Hi,

I'm new to B4W.

When I'm using from

while is being called after scene has finished loaded:


the seems to work fine but when I'm trying to use it after the scene has finished loading doesn't work.

Can anyone please help me with this one?

Hi Ranbuch,
In order to debug code, I need to see the complete project. Or you can make a small demo project that has the same issue. Use the "Export Project" function in your project manager to export a project zip file that I can then import.

O.K. I'll give it a try.

In the meantime, can you please refer me to some online demo with lights change if you have one?

What is your ultimate goal? Maybe if I knew what you planned to do, I could suggest something.

Here is an example of a light being turned on and off.

I need to allow the top Window alter the light energy of the scene within the iframe.

I can alter the scene with a function that I've wrote with but unable to do the same with a button click or a event from the top Window.

It's the same function The

this

is always the

window

object I've tried to invoke the function with

apply

but it doesn't seems to work. When debugging the

set_light_energy

method, in both cases it looks pretty much similar.

Thank you for your help.
