Hi,

I'm doing some particles with sprites, but seems to be by default with motion blur even with the motionBlur checkbox off.

And it's getting the motion blur parameters being off… ?

I don't know if is overwriting the flag somewhere or it's just a bug

working with 9.0.794

any guess?

Delete the “v” from the field called Velocity Attribute in the Mantra: Sprite Procedural shop. Or just set the velocity attribute to 0.

Hi Miguel,

Thanks for the help. I found that, but I just don't understand why the attribute v is overwriting the render flag.

I hate those things in houdini roll

My 5 cents
I really think that SESI has to find a way to “lock” or change the color of the parameter field if something is overwriting it. (as a key or expression)

For instance
If you are creating an attribute in POPS, “diff” or “Alpha” or anything to override the shader value, it must block the shader parameter.
