Houdini 20.5 Nodes Render nodes

Labs Impostor Texture geometry node

The impostor tool creates texture sheets to fake 3D objects in your game engine.

The impostor tool creates texture sheets to fake 3D objects in your game engine. The tool will create full octahedral, 3D, fixed axis and animated impostors. Below is a short video showing how to setup the tool in Houdini. https://www.sidefx.com/tutorials/game-tools-imposter-textures/

Parameters

Render

Pressing this button will render the impostor to disk.

Base Settings

Render in One Image

When this toggle is enabled, all frames of the impostor texture are generated with a lens shader instead of on a per frame basis.

Impostor Type

This allows you to set the impostor type that has to be generated.

Source Geometry

This needs to point to the geometry that should be rendered as an impostor.

Camera Rig

This needs to point to an OBJ level camera rig.

Sprite Resolution

This sets the sprite resolution. (Ex: If you have 8×8 frames at 128×128 pixels, this means a combined 1024×1024 pixel texture)

XY Frames

Sets the number of XY frames that need to be generated for the impostor texture.

Atlas Resolution

When Impostor Type is set to Octahedron, this controls the overall impostor texture resolution.

Octahedron Zoom

This controls the camera zoom amount for the Octahedron impostor camera lens.

Animation Frames

When Impostor Type is set to Animation, this controls how many frames you want to encode in the impostor.

Output Picture

This specifies where the output texture will be saved.

Output Geo

This specifies where the geometry generated for the Octahedral Impostor needs to be saved.

Atlas

Pre Multiply

This controls if the basecolor/beauty map alpha channel should be premultiplied.

Beauty Map

Enables/Disables the generation of the Beauty Atlas for the impostor.

Beauty Atlas

This specifies where the Beauty Atlas should be saved to.

Base Color Map

Enables/Disables the generation of the Base Color Atlas for the impostor.

Base Color Atlas

This specifies where the Base Color Atlas should be saved to.

Normals Map

Enables/Disables the generation of the Normal Atlas for the impostor.

Normals Atlas

This specifies where the Normal Atlas should be saved to.
