Title: HIDDEN Forest pack/Scatter Problems
Post by: banchan on 2015-12-04, 14:06:08
Hello,
i would like to know, if you all have the same problem than i've.
when i try to hide a Corona scatter or a forest pack, the objectfs (like trees) stay visible to the scene, even if  i pick the no visible camera and put 0 to the visibility.
If i try with the real tree no problem
Can you help me please
Thank u

You need to alter visibility of source objects, not a scatterer icon's itself.

Ok super ! i'll try thank you for the tips and one more question if i can,
totally different, can we make only a render of some objects, like if i have a scene with 10 objects, but i just want two of them to the render, (they receive shadows, light everything of course) because i knew with vray but don't succeed with corona.
Thank you again

I didn't fully understand the new question, but I suspect you are looking for something like object properties/disable shadows/visible to camera/etc, so this should be avoided in Corona - instead you can use rayswitch material:

I suppose you're talking about render selected / subset rendering. If so, look for this option in render setup>general settings>render selected. Choose selection mode that suits your needs, pick some objects and only selected objects will be rendererd. With all shadows, refl/refr and GI.

Thank you, both of you
Romullus find the answer that i'm looking for, very nice !!!
I never see this render selected, i have to look better :)
it's really easy to use!!!
Thank you again

two more questions :)

when i use the render elements, when i save the render with "save all" for example, all elements are not save, my Cmasking (i have 9) are not save,
wirecolor,ID, zdepth, CESSENTIAL and one Cmasking are, but 8 are not.
Do you why I miss again?

And is possible to paint with the Corona Scatter?

Thank you for your fast answer
