Hello,

I've got a particle system generating colored particles (ramp: $LIFE).

Then I instanced boxes to the particles.

Now I want to pass the color of the particles to my instanced geometry (boxes)

How can I do this? (an example hip file would be very welcome )

using H 9.1.173, windows xp

thanks,

bernard

Hey,

Here's a link for the "Houdini Master Class Course Materials"

http://www.sidefx.com/index.php?option=com...&Itemid=132

Download the "Shading and Rendering in H9" course material. In there there's some example files together with a powerpoint/openoffice presentations discussing the subject.

Hope this helps,

Cheers

Hello,

thanks for the link, but in the Powerpoint presentation I don't find anything of passing color to shader....

there's a file there called "procedural.hip" that does what you want.

OK, thanks ihab.

I looked at the hip and they used copy sops. Is it also possible without the use of 'copy sops' ?

I've got a Location POP emitting particles going through a Color POP( ramp with $LIFE)

I've use the Instance Geo . Connecting the Material SOP to my POPNetwork and overiding the color doesn't seen to work...

I want the cubes inherit the color of the particle points.

I included my hip file. Maybe you can find what's wrong.

Thanks,

hello,

does anybody have a solution for this simple scene: particle system, instanced geometry, transfer particle color(not 'point' color) to shader....

In Houdini 8.2 it was so easy as '1-2-3'....

thanks

hey,

the problem with your file is that the material sop was looking for primitive attributes (1st drop down menu) I changed it to point attributes and everything works as expected. When i used $CR, $CG and $CB in the colors of the material i had an error so i replaced it with a point expression. I attached your modified file.
