Hey guys and girls, just wondering (particularly dwight) if anyone can tell me how to get the lined type sunlight through windows.

Venetian blinds might do the job?

I think you are describing volumetric lighting. Like there is mist or dust in the air. Which program? I don't think Lightworks can do that.

shadow from tiny blobs on a sheet of glass?

It is hard to understand your visual idea from words. Why not experiment a little and post the results for ridicule. Or admiration.

Once you ar working with LightWorks it will be easier to get dappled shadows from leaves - divergent shadows are easy.

This is volumetric, also shown is gel or stain glass effect. C4D

As far as I know, you cannot do this with ArchiCAD 9 - LightWorks. This is an example from Cinema 4D. I tend to step out of ArchiCAD when I want a special rendering effect. You might want to do the same.

The effect of dappled light is enabled in C4D by toggling 'Visible Light' & playing around with the options of which there are many & varied. The tree, or blinds, or window frames, or whatever else you may chose, are merely the shadow casters, & will have no effect other than the shadow cast on the ground, if your program does not support 'visible lighting'...
I've attached a test render I did awhile back, it's not exactly awe-inspiring, but it was done to try & capture a certain 'feel' I had in mind. Consequently, I've never tried it again

If I were driving down the road and I saw this house, I would stop. It is awe inspiring, you are dead wrong about that much. Thanks for sharing your work.

The other point is, with C4D everything is a stage. Repeating the same effect is simple the second time through. Same environment, different house.

Actually,
As I've done it once & rendered the effect out as separate layers in C4D, I can just drag it onto any other projects in photoshop without having to re-render... Gotta luv mult-pass rendering...
Thx for the crit Mark Keep up the HDRI tests !

Cheers,
Justin

In the example Mark B. posted, this demo shows a simple spotlight in C4D with 'visible' lighting switched on. From here, the result is two-fold. One (seen on the left) is shadows cast in the 'visible' light by the window frame. The second is to show that C4D recognises the change in light colour when shone through coloured glass, and this also appears in the 'visible' light.... tricky eh ?
If your rendering package doesn't support 'visible' lighting, then this effect is unachievable unless you can master the look by air-brush in photoshop!

Start with a new light, make sure it's a spotlight. In the lights general settings, turn shadows to soft, visible light to volumetric. Ensure volumetric lighting is ticked in your render options, and a quick render should show the visible light. Add your shadow caster(s), play around with the bits, add a floor, materials, etc... My tute skills need work, but here's a quick image I did as I was writing this !

Like all good programs, community is the key. ArchiCAD-TALK is an excellent example of, "much to the credit of GS", user based involvement. Maxon likewise has a community.

Since you have a demo version of the software, tutorial files are very useful since they are half built already. Here is a link to some wild example files by Jeremy:

And here are some volumetric samples you can render yourself.

Looks like the box has a light panel inside of it, instead of light shining across the room, onto the glsss then finally onto the floor. There are so many ways to do the variation. Do you keep your computer on for days, while you test C4D? Without the save feature in the demo I used to do that sometimes.

One thing that is very productive - open several files and cut & past items between them to create a whole new scene. Think of null items as folders, drag what you want into a null object item and then colapse it, select - copy then paste into a new document. Texture missing?, Go to preferences, Texture Path - then find the folder it needs. There are so many things about C4D that make life simple, finding them the first time can some times be difficult.
