I am using hda in ue4 and I am adding vertex color into hda using PointVOP node its appearing in Houdini but in ue4, looks like it doesn't have vertex color.
in ue4's viewport "Show>Advanced>VertexColor option is checked

I am following this tutorial

thanks for quick reply, I understand that things on UE4 will get very difficult and slow. I asking for learning purpose, can I do it or not? do I have the option to choose? if yes then, how??

I am using Houdini's HDA in UE4. and, parameter change doesn't cook until the mouse button is released. is there any way to fix this. in UE4 I didn't find any setting that can help may be in Houdini some setting I can tweak to get what I want.
I just found one link related to my problem but it didn't help much.
