Fur thickness attribute ? Tweet

[WoutTgh]

Hi,

is the fur thickness attribute accessible on a point per point basis ?

Hi,

The Octane plugin gets the fur thickness from the "width" float point attribute, if available in the curve primitives.

Thanks,

Oh, interesting, that seems to work, but what about the tip thickness ? thanks !

Just do a gradient on curves and call it width.
If you use resample node and turn on curveu attribute, you should be able to do it easily. Turn off resampling if you don't need it.
After that create a wrangle node and write @width = @curveu;
@curveu attribute goes from 0 to 1 so you can fit it to whatever value you want. So the code should be:
@width = fit01(@curveu, min, max);

ooh of course, cool. And then just keep the obj paramteres setting at the default, or both 1 or whatever.

Thanks !

Yea keep it at default, it doesn't really matter. If you have width attribute, it's gonna override whatever you have in obj level.

Yes, thank you, very helpful
