Link Cy4D with xPresso

Recommended Posts

Hello forum,

I like making little XPresso rigs to speed up workflow. Right now I'm trying to make an infinite floor rig.
I'm trying to put a colour picker on the user data applied to my rig null.

I then use xpresso to drive the object colour of my floor disk, and then use a cy4d attribute tag to change cycles material applied to the floor through attribute node.

The problem I'm having is the set up I have for cy environment. I can figure out how to do two things.

1. have a link field on my rig user date to drop in an HDR image

2. Link the colour on the user data to drive the environment BG colour. 


I attached a file to take a look at. The BG material is set up based off a post I found on doing a split bg.

The first set of nodes loads a HDR image to light the scene but then the second node cluster is the background colour.

On the environment node I want to use a colour instead of an image. Its this colour info I want to get to through my xpresso.


Hope I explained this well enough.



-- dang it, I see zip files not accepted. The C4D file will have a missing texture image link then as an FYI

in your xpresso, drag and drop the material
now select the background node inside the material
go to xpresso, add whatever you want in the material node from node settings.

add custom data, change it to link, change interface to shader.
