Export Material Parameters not working in Houdini 20.5 2024年10月17日11:43
Hi, we use Material Parameters to pass data from Unreal into Houdini and this stopped working when upgrading from Unreal 5.3.2 + Houdini 20.0.688 to Unreal 5.4.4 + Houdini 20.5.370.
It seems like a big issue, I have a repro below, or is there something I'm forgetting? Thanks.
P.S. Is there a better way of passing data from Unreal to Houdini, say per spline?

- Create new material "TestMat"
- Add scalar parameter "TestParam = 26"
- Place Shapes > Sphere in the world
- Assign TestMat to the sphere
- With the sphere selected place PolyReduce HDA from Houdini Tools shelf
- Change "Percent To Keep" to see it's working
- Change "Houdini Inputs > Input Geometry > Export Material Parameters > On"
- Recook
- Open Scene in Houdini
- Open he_polyreduce, select input node
- Observe unreal_material_parameter_TestParam is missing in H20.5 but is present in H20
P.S. Is there a better way of passing data from Unreal to Houdini, say per spline?

To set the right size, use Heightfield Resample > Specify Exact Resolution > Grid Samples
Then use a detail wrangle with:
Or any other recommended setting:

Then use a detail wrangle with:
i@unreal_landscape_section_size = 127; i@unreal_landscape_sections_per_component = 2;

Hey Cody, that's great, if you could mention landscapes in the bug report (as that's what I was originally after), that would be great. Thanks!
