Noticed that the gradient node is not working properly. Tried to use one to control an texture for vertex displacement and I can swap black and white order to make it negative but sliding the ramp controls doesn't do anything.

If we enable Packed Geo Instancing on a geometry container with packed objects, toggling light IDs does nothing (it doesn't even create an update event to the IPR). If we disable the packed geo option (so the objects are automatically unpacked) lighting linking works properly.

Thank you Juanjo! Weird how no-one asked for this before. It is extremely useful in Houdini to control the displacement texture for example (UV not vertex) with point attributes.

If I multiply a procedural texture with a point attribute (Float_Vertex_Attribute) the Baked Image is incorrect and does not take into account the attribute color.
Setting the multiply node straight to Base Color for example I can see the wanted ...

Hey there,

We exported an animated alembic character in ORBX with its octane materials from C4D and imported in Houdini. Everything appears great apart from the animation. Is this not supported in ORBX sop node?
In standalone animation works fine.

thx

I saw the issue in the C4D forum but has anyone noticed this in Houdini?
Rendering the Object and Material ID AOVs for an animated sequence makes the color change every frame.
Is this a know bug? Is there a workaround?

Thank you for the updated Light HDA.
I believe a Perspective projection instead of UVW as well as by default black borders in the shader image is the behaviour people would expect 90% of the time for Gobo lighting scenarios. Of course everyone could tweak the hda to their liking but these seem like ...

Thank you for the update. When should we be able to see fixes for the gobo texture mapping for Houdini octane lights ?

I find the Area Light HDA broken to be honest. Just got back into Octane after two years in RS and I find it quite extraordinary that new stuff like Brigade appear while a very fondmental thing such as a proper Area Light with a Spread slider as in every other renderer is not included.

I can verify that the same happens with Lights.
If I create a Spectron Spotlight and tweak its Throw distance and Cone Width values IPR acts properly.
If I keyframe these and then try to tweak them, the IPR does not reflect the changes.
Deleting the channel and now we can tweak them again in real ...
