Canvases

andrey2-1990

Hello. I want to render a character and their shadow on whatever it falls, but I don't want to render the objects on which the shadow falls 

i tryed:

Select your figure on the scene pane, Select>Select Children then Create Advanced Iray Node Properties
In parameters put "111" (or whatever you want) as iray handle for everything
Select everything else from your scene EXCEPT your figure, Select>Select Children then Create Advanced Iray Node Properties
In parameters put "111" (or whatever you want) as iray handle for everything
In parameters Enable Iray Matte ---> "ON" for everything
Render Settings pane / Advanced Tab : enable Canvases, click the "+" and choose "LPE" instead of "beauty".
Copy paste this in expr : E '111' .* L
Render Settings pane / Editor Tab, go to Alpha, set Default Alpha LPE to "custom".
Copy paste this in Custom Alpha LPE : E ([^'111'] .*)? L?
Render Settings pane / Environment Tab : Draw Dome/Draw ground = "OFF"

But it doesnt work.

If you just want shadow you shouldn't need to resort to canvasses, though you will need to make sure that the surface settings for the shadow catchers are not reflective.

i want to get the character and its shadow. To then impose it on different locations. I've heard it can be done in 3d light, but I haven't found a single tutorial

Yes, just using the Iray matte in a regular render should do that.
