Houdini 20.5 Nodes Geometry nodes

Labs RizomUV Optimize 1.0 geometry node

Enables the use of RizomUV and performs a UV optimize inside Houdini

The RizomUV Optimize allows you to perform a UV optimize inside Houdini by running RizomUV on the background.

Parameters

Cook

Starts the cooking process for this step.

Auto Cook

This toggle controls if the node should automatically recook if any dependencies have changed.

UV

UV Attribute

The UV sets that are send to RizomUV to perform the actions.

Delete Original UVs

Removes the present UVs before processing in RizomUV.

UDIM Tile Offset (x/y)

Specifies the offset of the resulting tile in which the UVs are placed.

Optimize

Iterations

The number of iterations for the optimize algorithm.

Power

The optimization strength that compliments the number of iterations.

Angles/Lengths

The mix between conservation of angles and distances. A value of 0 will result in angle conservation, while a value of 1 will result in a distances conservation.

Prevent Flips

Avoids the creation of triangle flips. This can significantly increase the unwrapping or optimizing calculation time.

Prevent Overlaps

Avoids the creation of self border intersections. This can increase the unwrapping or optimizing calculation time.

Fill Gaps

Fills the gaps in the mesh by adding invisible and temporary polygons to the model. When an unwrap or optimize is performed, it prevents the hole from collapsing on various types of unwraps. Recommended to use on eyes, mouths, nostrils, clothing, or hard edge openings like the gap on top of a tank or non-square windows.

Settings

RizomUV Path

The path to the RizomUV executable.

Temp Mesh Path

The path to the temporary mesh file.
