Hi,
Thanks for the reply and I think you might be right.
The scene has heavy rainfall and water flowing along rooftops. It seems a
bit more than the RSMB standard version can cope with.
Think I might end up rendering it with MR motion blur. But the render times
are just horrible
Thanks again
Jesper

Hi Jesper,
isn´t the realflow stuff retesselated meshes per frame,?
That would mean you can´t compute the vertextransformation
per frame into a texture but would have to resort to use
the RSMB standard version (without extra vectors as input),
on that part of the image. I find the standard version gives great results
often enough (cutting on the need to render vectors).
Cheers

Subject: Getting correct motion vectors from a RealFlow mesh
Hi,
Im trying to get correct motion vectors from a RealFlow mesh to use with
RealSmart Motion Blur. Im using the Im2DMV_2 motion vector shader and it
work like a charm with everything but the RealFlow meshes. The vectors are
all over the place. Feels like I´ve tried everything
Does anyone know of another way of getting the vectors out of XSI.
Best regards
