Motion blur from camera animation Dec. 6, 2020, 1:22 a.m.

Hi Houdinians,

I have a question regarding the motion blur in solaris.

I have a shot where objects are still (no animation) and only the camera is animated.

I didn't manage to some motion blur due to the camera movement.

In other renderers if your camera is moving and your objects are still you get some motion blur on the objects due to the camera animation.

Where did I fail ? Is there a peculiar parameter to check on ?

Thanks for any help you can give.


Camera Depth of Field not working in 18.0.416 / Motion Blur June 17, 2020, 12:15 p.m.

Hi friends,

I am trying to get motion blur from an animated camera, my objects are statics, only the camera is moving. I tried layering differents nodes in different way, but I didn't succeed.
I can't help but thinking that it is simple, do you know how I can achieve it ?

This is my layering inside LOPS:

Thanks a lot !


Geometry attributes inside TOPS May 26, 2020, 11:55 a.m.

Is your tags attribute a string array? It looks like there's a bug with the geometry import and that attribute type – I'll get it fixed ASAP.

Hi Taylor,
My tags attribute is a string array.
I did a work around, instead of a string array I put my tags in a single string seperated by a coma, In TOPS I did a split() in python to filter the string and get all the tags in an array.

But I be glad to know if you do a fix for that !
