Hey,
When utilizing a Unity default shader for particles, the fabric has a “Required Vertex Streams” part and a “Apply to Programs” button.
This characteristic may be very helpful for fixing any particle system that isn’t set correctly.
How might I create such a button for a shader created with Amplify Shader Editor?
ASE has an choice to specify a “Customized Editor”. This allows you to override how the fabric is displayed within the inspector.
Right here’s the (restricted) official Unity documentation on the subject.
And right here’s the customized editor Unity’s particle shader makes use of. The “Apply to Programs” button is buried deep within the DoVertexStreamsArea() perform, seek for streamApplyToAllSystemsText to search out it.
Usually for a customized editor you must manually record out each materials property, and methods to show them. However you may as well lengthen an present materials editor class, like ASE’s personal, and in your class’s OnGUI() perform you need to be capable to name base.OnGUI(); to get the default ASE materials inspector, after which append your individual perform so as to add the vertex streams portion.
Sadly there’s no straightforward option to generalize that perform, because the order and elements utilized by streams is bigoted based mostly on how you employ them in your particular shader. And thus usually must be hardcoded into the customized editor. Unity’s has an inventory of streams that it builds by what options are enabled, and provides the suitable streams to the record within the specific order they’re wanted by the shader.
