Houdini 13.0 Nodes

interface version 1

Applies an image file as a textured shader to a surface (an enhanced version of UV Quick Shade).

  • The applied UV texture on a Stanford Bunny model. (A reflection-mapped variant is also shown). The texture image is automatically displayed in the UV viewport as well.

This is a convenience operator that lets you very quickly put an image file on a surface, as an UV-mapped texture and/or a reflection map. The texture mapping is applied both in 3D viewports and in mantra renders (as a matching mantra surface shader is also applied).

Features

Use Lighting

Lighting can be disabled on the model, allowing easier inspecting of the UV texture projections. This applies both to viewports and mantra renders.

Bump mapping (viewport-only)

The texture image can also be applied as a bump map.

Environment mapping (viewport-only)

An environment map can also be applied. This is useful to determine if curved surfaces have the appropriate shape for aesthetic reflections, for example.

Tip

Environment mapping might require the Specular component to be enabled in the viewport ('d' Display Options → Effects → Lighting/Specular).

UV Viewport Display

The selected texture will be automatically loaded in all UV Viewports as a background image.

Note

As opposed to the original UV Quick Shade SOP, this operator will not generate any UV mapping coordinates. Also, it is intended to be used as a display-only node (visualizer), not as part of regular geometry construction.

Parameters

Texture

Path to the texture file to be used. (The pop-up menu provides some default textures.)

Display in UV Viewport(s)

If enabled, the texture will be displayed in any open UV texture viewports.

Note

Newly opened UV viewports won’t update automatically. If the background image is not displayed, switch this off then on.

Diffuse

Diffuse color (both for viewports and mantra renders).

Use Lighting

Does the surface shading interact with lights (on) or it just displays the texture itself (off). This applies both for viewports and mantra renders.

Viewports – Diffuse, Bump, Environment

Viewport-only fine-tuning of the various shading components.

Tip

The image can also be applied as a bump map. (The quality is dependent on video hardware – the Bump Scale parameter has to be tuned very high on occasion.)

The environment map can be useful for checking the visual quality of curved surfaces (without rendering turntables).

To Do

  • Provide option(s) for easily accessing any texture file from the scene for viewport display
