Creating Good Shadow Geometry

[MaineLines]

I'm not happy with the results of the shadow geometry I have created. Even though the internal shape is as large as I can make it without it sticking out of my main shape, I still get light spilling over the top edge of the model on the shade side. Any one know of any tricks to prevent this? It seems to me that the shadow shape should not be adding shadow to the side of the vehicle that is allready in the shade.

I was looking for ways to edit/remove existing stencil shadows the other day and came across this, might be of some use to you.

Hiya, that link doesn't seem to work.

Welcome to the world of Shadow Volumes (Railworks Style) ... not fun at all

I make no recomendation on this method http://forums.uktrainsim.com/viewtopic. ... 7f8eb8bab1 , so your call on the use/misuse thereof .

Care to show a screen grab ( wires ) of the shadow mesh ?

Well that was wierd, sorry bout that. The link above was the thread I was after anyway.

Thanks very much for the link guys and thanks to Sly for the idea! It's a very interesting approach. I expanded my shadow geometry until it surrounded the car then flipped all normals to point inward, and am much happier with the results.

The 3DC Building Tutorial on this page http://railworksamerica.com/FileLibrary ... -2009.html discusses that shadow subject as well.
