mops randomize and mops transform modifier doesn't work

Post by meguru »

I was watching a donut tutorial and the video introduced MOPS. I used mops_Randomize and mops_Transform_Modifier to randomize sprinkles orientation. But they didn't work.

Could anyone help me look into this problem?

It looks like you have "Ignore zero falloff prims" enabled. If you don't have a falloff attribute upstream and this toggle is enabled, MOPs nodes will have no effect.

If that doesn't help, could you upload your hip file so I can take a look?

Hi, thanks for the quick reply! I disabled Ignore Zero Falloff Prims but it still doesn't have effect. I have my file in the attachment. Really appreciate for your help!

The reason this isn't working is a little tricky... you're trying to randomize the mops_falloff attribute, but you also have "Enable Falloff" toggled on and there's no incoming falloff attribute to speak of! In this specific case, MOPs Randomize doesn't automatically initialize a falloff attribute for you. I'll change this in future versions. In the meantime, the easiest fix is to just disable "Enable Falloff" on the MOPs Randomize.
