Generated Code Example

The following example code represents one possible outcome of this node.

_ChannelMixer_Red = float3 (OutRedInRed, OutRedInGreen, OutRedInBlue);
_ChannelMixer_Green = float3 (OutGreenInRed, OutGreenInGreen, OutGreenInBlue);
_ChannelMixer_Blue = float3 (OutBlueInRed, OutBlueInGreen, OutBlueInBlue);

void Unity_ChannelMixer_float(float3 In, float3 _ChannelMixer_Red, float3 _ChannelMixer_Green, float3 _ChannelMixer_Blue, out float3 Out)
{
    Out = float3(dot(In, _ChannelMixer_Red), dot(In, _ChannelMixer_Green), dot(In, _ChannelMixer_Blue));
