Hey all,

I hope someone can shed some light on this. I'm trying to understand the motion blur in the rop alembic OUT node.

I need to make them match with XSI, that why I need to understand them better.

Here what I think, correct me if I'm wrong…


- If I check the “use motion blur” box :

Samples : 0
Linear interpolation with no motion blur sub-frames. (ie frame: 5 / 6 )

Samples : 2
2 sub-frames (ie frame: 5 / 5.33 / 5.66 / 6 )



The Shutter also give me interrogation:

The XSI default is set to 0.25 - 0.75. Do I need to make my ROP alembic Shutter match with the one from XSI ?


thanks

After some test, I've clarified the meaning of these setting and make them match in XSI(arnold).

- If I check the “use motion blur” box :

Samples : 2
mean 1 sub-frames and the next frame. (ie frame: 5 / 5.5 / 6 )

Samples : 4
mean 3 sub-frames and the next frame. (ie frame: 5 / 5.25 / 5.5 / 5.75 / 6 )

For the shutter part, it's seam to clip between the values you give. Sorry, I'm not able to explain in number what it would gives, but I let it to the default values 0-1.

I hope it could help someone
