Motion Blur and Multipass

It seem that every time i tick the "Enable Render Passes" on the motion blur is not being calculated.
Is there a way to render multipass and still have octane motionblur?


Also, is it possible to render a 1:1 screen space motion vector?

Of course you can see on Live Viewer's title. 2.16 was first version for renderlayer, propably don't supports that. Soon, I'm going to release 2.22.1. It has several changes for also layer system. Grap and test it.

Dough! Never thought about reading the title of the window =)

But the other question. If i want a motion vector pass where 1 offset in value is 1 offset in screenspace. Is there a way to render this out or convert based on the normal motion vector output?

If you want to apply accurate motion blur in post you need to know how many pixels the current pixel is moving in screen space.
So if your base value (not moving) is 0.5,0.5 and your object moves 2 pixels to the left the motion vector should be -1.5,0.5
So if you want to make a 180 degree shutter motion blur, you just take the -1.5 / 2 = -0.75
In that case the pixel should be blured 0.75 pixels to the left.

Regarding the bug; it seems that when motion blur is active during multipass renders, its only the data passes that get the motionblur applied:
You could argue that it should be the other way around (Data passes not getting any motion blur, and beauity passes getting motion blur)

I am so sorry, i did not know about the release section. I thought you meant that it was a upcomming release. I was just looking in the download tab under account settings.
