I tried to create density value in SDFVolume and Colorize by ramp parameter.
But After use ramp parameter in attribvop node, output value was 0.(input float value is correct)

When I checked it with VEX, the color came out well.


Am I doing something wrong?
Thanks

The ramp is all black.

Right click the ramp and select revert to defaults to use the ramp defaults visible on the ramp vop.
