Just wanted to see if nyone else has noticed a bug when mixing BSDFs with mtlx mix

when set to 0 it shows input1



and when set to 1 it also shows input 1



if you use a value of 0.001 it does show input0



this seems to occur specifically with the BSDF mode.

this makes shader building difficult. It seems when a constant is plugged in with the value of 0 the issue does not occur



would be great to see if anyone else has had this issue?

Best,
Rich

I'm seeing the same thing. It works fine when driven by inputs like your constant or a noise, but yeah, it seems like the Mix parameter on its own is borked.

I think there was a bug that was recently fixed for nodes with inputs at default values not triggering an update.

Fixed a bug with retranslating a shader node parameter when it's set back to adefaule value, which would not get reflected in the USD shader on the stage.

I guess it hasn't been backported
