I would like to know if there is a way to debug in the deformer graph, a print, or draw some raycast, anything. it would be really useful, even in the HLSL. any suggestion will be really appreciated.
I’m using UE 5.5.4

if you have the “Draw debug” Node in the deformer graph in mind, i tried that, it doesn’t work, or i have no idea how to use it, which seems much likely. if you kindly could tell me how to use it, i would be more than happy. thank you.

English is not my primary language.

Thanks for the question!

The debug draw data interface is something still early in development so apologies for the confusing UX.

To use the debug draw data interface, in your kernel you can do something like:

ReadDebugDraw().AddLine(Position1, Position2, White);

You can consider the debug draw to have these functions

struct FDebugDraw
{
    void AddLine(float3 Pos0, float3 Pos1, float4 Color)
    {
    }

    void AddCross(float3 Pos, float Size, float4 Color)
    {
    }

    ...
};

For more details, you can take a look at: Engine/Plugins/Animation/DeformerGraph/Shaders/Private/DataInterfaceDebugDraw.ush
