Hi there,
I created a simulation using mparticles in pflow that I need to use several times. For that reason I thought it would be a good idea if I baked it. The best way to do this, that I found, was to use a mesher (compound objects) on the pflow event and export the result to an alembic file. Then I imported it using a vRay Proxy. All looked well in the viewport. But if I render it I don't get any motion blur.
I read online, that the 3ds max exporter stores the velocity attribute under the wrong name. So I figured maybe it would help if I converted the .abc. to a .vrmesh. But it did't. Then I checked the content of the files (both .abc and vrmesh) using "ply2vrmesh" tool again and I coudn't find any velocity attributes. So I guess they weren't exported at all.
So I checkt the vray help again and I found this on the alembic support page:
"All geometry types support motion blur, either through a velocity attribute or through interpolation."
Since I have no velocity attribute (at least I think so) I would need to use the interpolation approach. But unfortunately I have no idea how to do that. Can anybody help me with this, point me in the right direction or something?
Any Help would be much appreciated. Perhaps the whole approach is stupid and I need to do something completely different. Is there by any chance a way to export a pflow simulation to vrmesh directly?
I am using
3ds max 2018
vRay 3.60.01
