Pelle Herfst Posted May 9, 2009 Share Posted May 9, 2009 Hello , For a project i would like to use solely the shadows projected on a white floor and not the subject that is used for projecting the shadows. In this case I use the 3d people figures. Any tips ? thanks Pelle Quote Link to comment
michaelk Posted May 10, 2009 Share Posted May 10, 2009 Would a gobo work? michaelk Quote Link to comment
Pelle Herfst Posted May 11, 2009 Author Share Posted May 11, 2009 Hello Michaelk, No a gobo is not what i am searching for , I want to use the 3d figures and be able to change their positions, render it in renderworks final with a light to create their shadows. Then finally I would like to lose the actual 3d figure and want to see only the shadow projected. Quote Link to comment
David Ormsby Posted May 11, 2009 Share Posted May 11, 2009 I think RW is geared toward recreating the real world, and something like this may be beyond it's means. Cinema4D could do it I think. My suggestion would be to do multiple renders and take it to photoshop. One render without any people to get your "floor" and put that in your bottom PS layer. Then change the texture on your people to a single color, so you can easily select/mask them out. It's an interesting result. Just curious what the goal is for the renders? Quote Link to comment
cad@sggsa Posted May 11, 2009 Share Posted May 11, 2009 (edited) Creating a tranparent texture and applying it to each part of the figure almost worked..... there was still a bit of a "ghost" rendered. maybe if the texture is refined it could worked, just used a simple transparency at 100%.

Pelle Herfst Posted May 11, 2009 Author Share Posted May 11, 2009 Thanks for the tips , David and Carl, I got this far also. In the end I needed to export this to photoshop anyway, so the layer export is probably the easiest way. Quote Link to comment
michaelk Posted May 12, 2009 Share Posted May 12, 2009 This is probably too complicated, but it works... There are two shadows on this drawing, one from the running man figure in the drawing and another from a duplicated running man shrunk down to 2" (5 cm) tall and placed very close to the light source. If you kept the lighting very simple you could map the position of the figure on the floor to the position on an imaginary miniature floor right next to the light... But photoshop is probably easier. michaelk Quote Link to comment
David Ormsby Posted May 12, 2009 Share Posted May 12, 2009 I stand corrected - if RW cast shadows from something transparent that's not very real world is it? Still curious Pelle - mind sharing what you are using this for? Quote Link to comment
cad@sggsa Posted May 12, 2009 Share Posted May 12, 2009 Thanks michealk Didn't think of that one. Should have thought of it as I watched a vid recently with that in it.... .....and I can't post it here due to type of file (.wmv) Quote Link to comment
Pelle Herfst Posted May 12, 2009 Author Share Posted May 12, 2009 Thanks Guys, A combination of the tips work good for me. to place the figures closer to the lightsource is great when mapped out. After that photoshop will do . David; to temper your curiousity ; it is meant for a visualisation presentation for an outdoor project to videoproject several people shadows on a street at night in combination with real shadows from the light of the same projector of the visitors in the street.
