Hello everyone.
I am newbie in modeling Smile

and have simple question.

How does directional light work? I've tried to put it in direction of a wall, then CTRL+ALT+L but there is no light.

Can I use it on a wall (with jpg as texture)? I know that for lights important thing is normal vector but couldn't find anything in editor.

In order to see the reactive of any light(s) you have to render the scene first. You can do this by generating lightmapping from the Edit menu. Not only will you see lighting effects, but also shadows.

some of these may help you:

I am not even sure that Ctrl+Alt+L actually do anything. Ctrl+Alt+R will add the current scene view for the raytracing queue. That is best done after applying the lightmapping.

Many thanks guys Smile

I have to admit to indulging myself in looking through the DeleD forums at peoples work, there are some truly skilled artists here. I have gained so much from this community.

I also noticed more recently, that the last model I made was almost one year ago :O Will have to fire up DeleD again. Never know, I may even finished the Christmas scene I started almost 18 months ago.

Hi again. Thx for response and links, I've looked at them, but didn't find solution. Maybe I had misunderstood how directional light works.

I've got simple cube with textures on walls (inside) and put there directional light, lightmapped and got nothing ;/ Shouldn't directional light elighten interior? I tried big numbers for intensity Smile

.
Point and cone lights works.

Also I have problem to load exported cube .obj in irrlicht. Firstly I need to set normals to point inwards, because there is nothing inside cube after rendering. Is there a way in DeleD to set normals?
And there is a problem with loading model in irrlicht when I set also normals(face) to export.

Maybe you could tell me how to properly create cube (as a room), fill textures on walls and export it.
What I've done:
- create cube 1k x 4k x 4k
- hollow it
- select faces (interior walls) and put textures
- export (default options - without triangulation and normals)

I don't know what is wrong when exporting normals. In file I got

Create cube
Clone cube, size the clone slightly smaller on all sides then the original.
Subtract.
That will give you a hollow cube with faces inside.

As for the directional light, have you set the color of the light? It's in the properties. If you don't set the color, you will not get any light.

Hope this helps a bit.

As I said previously, there are 2 types of directional light.

One simulates the Sun and like the sun, will not fill the interior of a cube unless there are openings. You could try and drag the Directional Light object into the cube, but I'm not sure it is supposed to work that way.

The other type of light is a Spotlight, I believe this is the type of lighting you are looking for. You can adjust the 'snoot' properties of the directional cone, in many ways to get the desired effect you are looking for. Make the front cone wider for a larger coverage, much the same way a lampshade works. You may have to adjust the falloff and radius of the 'snoot' depending on the volume of your cube. Place this type of lighting within the cube.

Making a cube the way Trucker2000 described will create a surface with normals you will need. The method you used created a Mass, not a Volume. Mass being solid, a Volume is a measure of space.
