Hey there!

Is there a way to turn on / off different layers in the Reflectance channel using the Python API? I want to be able to toggle the eyeball switch on my Specular layer based on some User Data. Any help would be greatly appreciated.

Thanks!

Hello,

Reflectance is currently not supported by the Python API. You can only access it with the C++ Material class[URL-REMOVED].

Best wishes,

This is now possible.

thanks for the update, is it now possible to enable/disable individual Reflectance Layers in Xpressso?

My hack is going to be just to turn the Brightness to 0% otherwise lol

Hello,

the activity state of a reflectance layer is stored in a flag, not a parameter. So I'm afraid it is not possible to edit this value using XPresso.

Hey,

Thanks for the answer. I did test using Xpresso to turn the Brightness of the Color channel to 0% and it works the same as turning the flag to 0. Or at least it Renders the same, not sure on the back end.

I need to get back into Python and C++ again. Xpresso can do so much though.

Cheers,

Matt
