New issue 1183: "Failed to split grids" when volume rendering GIZMO data https://bitbucket.org/yt_analysis/yt/issues/1183/failed-to-split-grids-when-... Sanghyuk Moon: I encountered a problem trying to volume render GIZMO snapshot. The other visualizations such as `SlicePlot` and `ProjectionPlot` were all successful. But everytime I try to create `Camera` for the volume rendering, I got the message "*Failed to split grids.*" and returned `ImageArray` is just black image. Has anyone resolved this issue? Here's the code I typed. ``` #!python tf = yt.ColorTransferFunction((-2, 1)) cam = ds.camera([2.0, 0.0, 2.0], [-0.1, 0.0, -0.1], 0.10, 256, tf, fields=('gas','density'),log_fields=[True],no_ghost=False) tf.add_layers(4, 0.01, col_bounds = [-1,0], colormap = 'RdBu_r') cam.snapshot("v1.png", clip_ratio=6.0) ``` And here's the output ``` #!python ImageArray([[[ 0., 0., 0., 1.], [ 0., 0., 0., 1.], [ 0., 0., 0., 1.], ..., [ 0., 0., 0., 1.], [ 0., 0., 0., 1.], [ 0., 0., 0., 1.]], [[ 0., 0., 0., 1.], [ 0., 0., 0., 1.], [ 0., 0., 0., 1.], ..., [ 0., 0., 0., 1.], [ 0., 0., 0., 1.], [ 0., 0., 0., 1.]], [[ 0., 0., 0., 1.], [ 0., 0., 0., 1.], [ 0., 0., 0., 1.], ..., [ 0., 0., 0., 1.], [ 0., 0., 0., 1.], [ 0., 0., 0., 1.]], ..., [[ 0., 0., 0., 1.], [ 0., 0., 0., 1.], [ 0., 0., 0., 1.], ..., [ 0., 0., 0., 1.], [ 0., 0., 0., 1.], [ 0., 0., 0., 1.]], [[ 0., 0., 0., 1.], [ 0., 0., 0., 1.], [ 0., 0., 0., 1.], ..., [ 0., 0., 0., 1.], [ 0., 0., 0., 1.], [ 0., 0., 0., 1.]], [[ 0., 0., 0., 1.], [ 0., 0., 0., 1.], [ 0., 0., 0., 1.], ..., [ 0., 0., 0., 1.], [ 0., 0., 0., 1.], [ 0., 0., 0., 1.]]]) (dimensionless) ```
