Houdini/Unreal: Auto-Assign Unreal-Materials, Bring Houdini-Materials to Unreal, Bake in Unreal

Houdini2Unreal Doc: www.sidefx.com/docs/unreal/in...
00:00:01 Introduction
00:01:30 Create Digital Asset and bring it into Unreal
00:03:38 Auto-Assign Unreal-Material
00:05:20 Bring Houdini-Material and Texture into Unreal
00:11:35 Bake Texture from Houdini-Output directly in Unreal
Note: If you bake a flow map, this map needs to set "flip green channel" in unreal.
This video explains the basic workflow of bringing a cube as Houdini Digital Asset into Unreal and making use of Materials (both, already existing Unreal-Materials or create a new Material/Texture coming from Houdini). Also, we'll setup a Houdini-Bake-Node which we'll trigger from Unreal to update our bake results after we modified our digital asset in Unreal.

WOW! This was far the most perfect tutorial I have seen for this topic! Everything well explained, step by step, clean, smooth and beautiful! Thank you so much!

[@workflowinmind]

Thanks for the video!! 6:46 You can also middle-click the parm which will show the full path, copy from there and repaste, it will keep it absolute

[@workflowinmind]

10:01 You need to use *unreal_material_instance* if you want your textures from houdini to be used. You can use *unreal_material_paramater_NAMEOFPARAM* to set any value on the instance

Thank you so much! Searched through all the KZbin for this exact information! Thank you! (Editable baker node - that's critical)

[@MichaelKlimenko]

Had the same issue with different levels of digital asset and baker (Geo vs Subnet). Thanks for sharing! Keep up with the good tutorials!

Awesome tutorial! Answer to my prayer.

[@CarsonVisuals]

Fantastic!

[@GarmanHerigstad]

Thank you so much!!

Is there a way to do this but instead of referencing Materials, referencing Static Meshes or Blueprints inside unreal so I don't have to do it manually everytime? Thanks

[@frenzyfol]

I don't think the combination of a (Material Network - Principle Shader) AND an Unreal_Material attribute work together anymore. I can only get either the textures to import, or the unreal material to be assigned, never both.

Hello, Simon! Thank you for such a great video I'm working on creating an HDA tool for Unreal as a part of my uni project. The question is if I can use an attribute in Unreal Engine to drive some parameters in my material instance. Basically, I spawn a lot of decals, and for these decals, I have a list of Textures (around 50) and more importantly, the system should be flexible enough to get a fresh list of textures and quickly integrate it into the system. I don't really want to go one by one and create material instances for each texture every time. That's why I'm looking for a smart solution for it. Are any ideas on how I can figure it out?

[@UnrealSimon]

I'M afraid I can't help much. I didn't touch HDAs for a while and as far as I know the Houdini Engine Unreal Bridge changed over time. So I'm not even sure if my video is still up 2 date...

[@N3.1Kryuk]

@@UnrealSimon Thank you anyway for your answer and for this great video! The techniques you covered still work

[@N3.1Kryuk]

​@@UnrealSimon Is there any chance you could recommend someone I can contact to help me with this question?

Hey Just posting this here as i was struggling with this yesterday, this only works when you're baking assets inside Unreal. If you're trying to Import Geo from Houdini into UE4, it will not be able to auto assign materials unfortunately.

[@kwiidnc]

you can (for me unfortunately materials assigning to collision_geo, instead main_geo), but its works

[@MrNolan515]

@@kwiidnc how do you do it?
