Texture creation - material emissive channel hardcoded to grayscale

[huwb]

Hi guys!

Is there a reason the emissive texture is hardcoded to be grayscale?

https://github.com/sideeffects/HoudiniEngineForUnreal/blob/Houdini17.5-Unreal4.23/Source/HoudiniEngineRuntime/Private/HoudiniEngineMaterialUtils.cpp#L2041

We have a case where we need coloured emissive and are wondering if this is hardcoded to grayscale for a reason.

Thanks Huw
