I guess there's no solution yet for the 'semi-shadow' a glass object would make. I'm doing something for some architects and checking out a rough model. Afaik, the only thing I could do is separate the pieces and render with and without shadow, then combine subtly in Photoshop.
Any other ideas?
Modern architecture scares and confuses me. :-\
I thought Bobby was doing something like that recently by doubling the object, then making the double of the object a solid and set it to be invisible but still casting shadows.
You want this item in Terragen?
And with vortex and sss + merge ?
No, Bastien, it's an object that needs detail, and was just used to show my question.
Thanks, fleetwood. Don't know exactly what you mean, but I'll start experimenting.
What I meant was two objects are positioned in exactly the same location. One is visible but shadow casting is turned off. One is invisible but shadows casting is turned on.
Yes, I just tried that, but with certain parts invisible. It's kind of what I wrote in the OP, but it's good that you reminded me. Instead of making each object in several pieces make the opacity of parts black works just as easily. What would really be great is a way to have glass make a bit of a shadow, not either a full one, or none at all.

That coinsides with my wish for true caustics in water and glass...my test was only sorta successful
I think it may be something to do with the render engine itself. It could be a raytracer issue? If light photons are passing through a medium with the certain type of thickness and IOR then some slight shadow should be produced?
You could render the object separate over the other parts in Lightwave with real transparency for the shadows.
But i think i would prefer your method too Ulco. Less software and different things to deal with.
I found this post from Matt:

Looks like it is still the same (transparency all or nothing). TG 4 hopefully ?
The image looks nice by the way.
We'll keep Matt busy ;) Thanks guys.
Yes, i would think as thick as your glass is, something of a slight shadow should be present.
