I'm having the exact same problem after debugging a project for a client, I found out that houdini engine with houdini 20.5 and unreal 5.5 just doesn't work.

Thank you so much for verifying. I was going out of my mind


Ok I might have found a fix, I reinstaled the engine, houdini and the plugin.
Them backup your pref folder in the docs (the houdini20.5, where your otls live and everything)and delete it so houdini creates a new one when you open it.
That did the work for me!

Hi, does anybody know how to export Houdini hair’s uv as a groom_root_uv attribute into Unreal 5.0?
This is the att to paint tex on the mesh and transfer it to the hair right?
Just use a rename attribute on the uv attribute and rename it to groom_root_uv, if it doesn't work take a look at the unreal doc and see what type of att it is (float etc...) and convert it to that.

I can’t seem to arrive at exporting the udims in texture form or figuring out another way to use them in shaders.
Can anyone help me out with that ?

I’ve tried messing with the height field output node.
The only way I got it working is using a for each node and manually changing the single pass value as wel as change the number.

I`l automate it and post it here but if anyone has a better solution I`d love to hear it.

Try to use a COP net set to volume slice and with center on 0.5 / 0.5.
In there you can treat the tex masks as images!

Hello everyone! I'm doing a groom with h20 and I was all crazy about tex mask paint node, but I found out when switching between 2d and 3d mode sometimes the node freaks out and vanish with all my paint .
And no I didn't hit the clear button even tough the 2d and clear button are close friends.

I'm on a Ryzen 7 1700 / Rtx 3060 Studio driver 546.01 / Houdini 20.0.533 (daily).

Let me see If I undestand it correctly, are you using the new houdini feather system? and this green geo on your picture are the barbs?
You need to transfer the color to the Cd_barbl and Cd_barbr attribute, in the feather interpolate also you need to pass them on
I usually use a feather ray on the template stage to color them acording to the ref (you need to generate the uvs https://www.sidefx.com/docs/houdini/feathers/texturing.html)
Them after you transfered the Cd to the barbs you import it on your feather procedualm them the att will be available on the shader

(not sure if this is the norm but it worked for me )

Hello everyone, I was taking a look at the old muscle system:
https://www.sidefx.com/docs/houdini/character/object_level/muscles.html [www.sidefx.com]

And I was wondering if there is a similar use in the new one (cheap for simpler characters)? I tried to setup some franken muscle on the new one but it feels a lot overkill for simpler bulge on character skin... Is there a way to use the old system in H20?

thank you.
