Once you imported an Alembic Cache, the object in Blender will have an Alembic Cache Constraint.
- Check Override Frame.
- Go to your desired starting frame. Type
1in the Frame property. Hover over the property and press I to set a key. Set a key on the next frame with the value of
2. In the Graph Editor, press ShiftE and select Linear Extrapolation. Then select the first keyframe, press T and make it a constant key.
Using a python expression
Type the following expression in the frame property:
#(1 - round((frame - frame_offset)%0.99999)) * (frame - frame_offset) + frame_hold
frame_offset with the desired starting frame. Replace
frame_hold with the frame which is held before the starting frame.
frame doesn't change, it is a python variable holding the current frame number.
Example. To achieve the following:
Frame Calculated 11 2 | 12 2 | The frame held before is no 2. 13 2 | 14 2 | 15 2 < This is the starting frame (15). 16 3 17 4 18 5 19 6 20 7
The expression would be:
#(1 - round((frame - 15)%0.99999)) * (frame - 15) + 2
