Kévin Dietrich (kevindietrich) planned changes to D2388: Cycles: add support for rendering deformation motion blur from Alembic caches..

Please ignore the velocity and acceleration discussion, that was a brain fart from me. The explanation is rather simple actually: the velocity property gives us dP when we need dPdt (so the values make sense in the "point in time" in which we use them). We might still need a user setting to make sure dt is the correct value for the velocities, instead of relying on the FPS (although in practice they are the same).

I don't understand some of the design in the patch.

  • Why is there a change in the Scene RNA required? The fps and fps_base properties are already exposed in RNA, and having two ways to reach the same properties seems unnecessary.

Kévin Dietrich (kevindietrich) added a comment to T69046: Cache loading via animation system.

I just found out about this task/idea after trying to update D2324. One thing to note about D2324 (and any other potential system) is that the properties are read from a CacheFile whose evaluation is inside the dependency graph so we have to be able to set a relationship from the object (or ID) to the CacheFile. Now, D2324 does not work anymore for this very reason: there does not seem to be a way yet to set this dependency through the F-Curve Modifier's API (unless I missed something), therefore we do not have a valid CacheFile handle to read the data from because the object might be evaluated before the one for the CacheFile, and it is simply crashing.

Kévin Dietrich (kevindietrich) added a comment to T49234: Alembic not importing motion blur.

You have to apply the patch and compile Blender to test the feature, it is not in the daily builds. Also your file does not have velocity information (the array size is 0). So without the patch and without custom velocities, Cycles is just using an interpolation between the previous, current, and next frames.

I rewrote the algorithm to make use of 8x8x8 cubes since the marching cube idea with a cube size greater than one does not really work; for it to work we would need to interpolate all the voxels around the corners of the cube within a distance equivalent to the size of the cube; which is not efficient.

Kévin Dietrich (kevindietrich) added a comment to D3038: Cycles volume : fast empty space optimization by generating a tight mesh around the volume..

I wasn't thinking about the marching cubes algorithm actually, but rather axis aligned quads between empty and non-empty voxels. And then you'd make that smarter by considering e.g. 8x8x8 cubes instead, and merging neighbouring quads and deduplicating vertices to reduce memory usage. For OpenVDB files that would then also naturally work by building around leaf nodes, without having to read the actual voxel data.

To define whether or not a mesh is animated, the exporter only checks for the presence of modifiers and shapekeys. Since your script is using a scene handler and recreating the mesh every frame, it is not possible to know that this particular object is animated (unless there is some hidden black magic I am not aware of).

Vertex colors are a mesh property in Blender, so it is not possible to import/have them on curves at the moment. Making use of polylines (or edges in Blender terms) would be possible, but then things like rendering in Cycles might not be possible or very limited. The fact that Houdini polylines/polycurves are imported as curves in Blender is because they are written as being curve objects in the Alembic archives.

Kévin Dietrich (kevindietrich) added a comment to T50403: Alembic: locations issue.

The issue most likely comes from the confusing logic that is used to convert data between Blender and Alembic, especially Alembic Y-up matrices to Blender Z-up ones. In the process, to create the Blender matrices, we multiply the matrices of the Alembic object with the one from its parent recursively, so maybe in this case the object matrix is somehow multiplied twice. The relevant function is in abc_util.cc.

Kévin Dietrich (kevindietrich) changed the status of T50263: Mesh imported from alembic crashes later from Unknown Status to Unknown Status.

I guess we can close this since the issue appears to be resolved.

Kévin Dietrich (kevindietrich) changed the status of T50401: Alembic: instances are not supported. from Unknown Status to Invalid.

Although I'll try look into this shortly, I'm going to close this ticket so as to not have too many open tasks cluttering the bug tracker. I added a note about it in my personal to-do list anyway. (Also: not a bug :) )

Kévin Dietrich (kevindietrich) added a comment to T50370: Problems (yet again) with Linked Objects that have Alembic Cache applied.

There is no bug here, if you tick the Override Frame check box, it will use the provided frame number from the Frame field to lookup the cache. If you want to overwrite the animation over time you need to set some key frames on the Frame field.
