The character "ž" was the issue.
I'd want to ask you about the VOLUME GRID loading. When I insert it in the scene and move the camera, the scene begins to parse. This means that anytime I walk around in my scene, the new point of view takes a long time to load. It appears that the volume grid must be loaded every time I move the camera. Is this proper behaviour?
Is there an option to scale the volume grid? Consider constructing a volume grid as a VDB sequence with a different measure unit, such as meters or millimeters, rather than the native C4D cm. When importing, the volume is too tiny. I can scale it by moving to object mode, but I'd want to have the SCALE attribute within the volume grid.
