Export just shadows
-
Can you share your model ?
I have never tried this either. For the moment, if I choose Hidden lines mode and uncheck all the edges I get this.

Go to Face style and select hidden lines then uncheck all the edges. Also uncheck the sky.

thank you for taking the time to look at this and thanks for the answer

I've done a tutorial on this here on SCF somewhere. I use shadow only exports frequently to create soft shadows and the appearance of multiple light sources.

still struggling with this one. If I export to png or tiff for a transparent background then I end up with the box again as this is not transparent. Is it possible to export with a transparent background?
thanks

thanks John,
can do but wondered if there was a way of managing it in SU

With 2015 you can export ,png with transparent background.
Like this. -
Do you have a copy of the skp you have used for the .png? I have exported to png (transparency) which is where the object was visible.
thanks

I don't know if you can exclude a 3d shape shadows, on a mac...
have a look at tig's Shadow Projectorhttp://sketchucation.com/forums/viewtopic.php?f=323%26amp;t=41885
you can hide everything else than export a png/tiff of just the shape of a shadow...

some rendering apps can render only shadows with transparent everything else.
the upside is you get very clean shadows which render relatively quick.. the downside is it's maybe overkill for what you're trying to accomplish in the end.so what, exactly, are you trying to accomplish?

Thanks. I am on a Mac.
I wanted to just export shadows only with a transparent background.

like that's it? that's the final goal?
my point is that there may be other ways to reach your goal

Jeff, Dave and I also use mac...
I think tig's plugin or a renderer are the options...
how are you wanting to use the results?

I am following this http://www.ronenbekerman.com/making-of-urban-plaza/

Thank you. At least I know that it is not possible to export shadows only with a transparent background on a Mac without a plugin
Thanks again

just a fwiw..
you've been able to do this forever on Mac (natively).. Windows has just gained the capability in su2015edit-- oh wait.. I misread what you wrote..
I'll look at it again later when I'm at a computer.

Is that what he did in the tutorial (great link--fine artist BTW)? No he just used a hidden line, white background, no-edges shadows export to png, and set the layer in PS to multiply.
If you want you can set png to transparent background (in the export dialog "Options"). The objects will still be white but you can set the color to alpha in PS (works with white background as well anyway).
