Hi Paul,
I was wondering if you could integrate "object motion blur" in the next release, because the are animated object in archicad like cars and doors.
Thank you.

My understanding is that the ArchiCAD API does not allow a plugin to access the "path" coordinates of moveable objects. So I do not believe this would be possible.

Exporting the scene to Standalone (in ORBX format) with each frame's vertex position stored in an Alembic format animation would be possible - but for large scenes would take a huge amount of disk space. If done this way, the scene could be opened in Octane Standalone and rendering with Vertex Motion Blur. Once I get the AC18 version of the plugin done, I will look at this in more detail.

Hi Paul,
Did you get any wiser with AC18 and possible motion blur for plugin?
some standard AC objects like the cars being able to animate linger for motion blur
(It might be very interesting for other stuff too.. I am working on ways to get any gdl move in Archicad by simple programming the gdl)
Cheers,

Hi Jeroen. Object motion blur is going to be problem because the plugin will need to pick out the moving objects whilst in the Photorenderer, and a Photorenderer plugin cannot query the AC API for the object properties. So I think a simpler solution is to enable a mode where the plugin exports the entire animation as an Alembic ABC file in an ORBX, which can be opened in Octane Standalone, which can render with vertex motion blur. It's is tricky to implement (because the export process will need to use the Photorenderer), but I can look at this in the next month or two. Would you say this has higher priority than the grass/fur generator, or lower?

Paul

Hi Paul,

Object Motion blur is cool, but grass/fur generator is more dear to me
Maybe others have different opinion.

Even though with your scatter tool in the plugin and the phanthom scatter a lot is possible.
Can you tell a little more about the grass/fur generator bringing even more? I am very curious to your plans about that

Cheers, Jeroen

definitely grass for me to

My thinking is there would be a little checkbox on a material to make it "grass". Then when loading the scene into Octane, geometry with a "grass" material would have the current scatter generator applied to create 2 or 3 vertex hair strands with a little variation. But no promises - this might be end up being more complex than that.
