    I am trying to calculate particle position in world space. And I converted part of the graph to a subgraph.

    All graph and sub graph is set to world space.

    but still I got this in the generated compute shader.

    the graph is working as expected before partially converted to subgraph.

    Hi @Lieene-Guo ,

    I believe this is a known issue. I've linked your post here to the bug case to bump it up in priority.

    Hey @Lieene-Guo ,
    There is a fix for this in the 10.2 package, disabling implicit space transformations in subgraphs.

    We'll need a more comprehensive refactor to address spaces in graphs more robustly, but for now this fix will allow you to control the space from outside of the subgraph manually and avoid the confusing automatics conversion.
