Hi, I am looking for a way to import Houdini particles with matrix information(especially rotate and scale) by Alembic, import in Cinema4d and render as geometry by Octane.
The octaneObjectTag can not be used, and it seems that there is no alternative but to scatter geometry on particle points with cloner or OctaneScatter.
So I tried two methods. First,I thought that the matrix could be reproduced by using Houdini to force Cd to have v, N, and pscale, and apply the Mograph shader effector that loaded the vertex color map, but somehow it did not work. Not very familiar with C4D vertex maps ...)
Second,Houdini exports particles with triangles on particles, and Cloner distributes them at the center of the polygons. The cloner's scaling function has been able to reflect rotations and scales, but octane doesn't apply motion blur, it's probably because the cloner rearranges the clone index every frame, as particle geometry disappears and is generated prematurely ...
Since I want to refer to high resolution geometry finally, using the vertex speed of octaneobjectttag based on the velocity vertex map of low resolution geometry created by Houdini makes motion blur funny.
Applying high resolution geometry to particles without reference is not practical due to memory problems (HoudiniEngine also has this problem and must eventually be referenced in Mograph)
Can anyone solve this particle export problem from Houdini to Cinema 4d?
This is my test .c4d and .abc
