## The Main Properties
These two are the two properties most important:
These are the 3 most important properties
- `_DMXChannel ("Starting DMX Channel", Int) = 1`
- The `_DMXChannel` instanced property is where you'll set the starting DMX Channel for your DMX shader. DMX Channels start reading from 1, so 1 is the default. This is more of a "raw" channel number and should be used only for world shaders when its controlled by the `VRStageLighting_DMX_Static` script.

- `[NoScaleOffset] _DMXGridRenderTexture("DMX Grid Render Texture (To Control Lights)", 2D) = "white" {}`
- The `_DMXGridRenderTexture` is where the DMX Grid render texture will actually go. You can find the render textures in: `Packages/com.acchosen.vr-stage-lighting/Runtime/Textures/RTs`. There you can find the horizontal, vertical, and legacy versions of the textures. I recommend using the `DMXRTViewer-Interpolated-Color+Intensity` prefixed render textures as those are the slighting smoothed versions of the RAW render texture counterparts.
These two properties are required for all world-based DMX shaders (for now).
The first property is required for world shaders. The last 2 are required for avatar shaders.
