PxrBakeTexture can be used as a pass-through node for baking patterns networks to 2D textures as part of the baking workflow.
Parameters
Input Color
This is the incoming result of the pattern network to be baked. This connection requires a color (RGB). This input takes precedence over Input Float.
Input Float
This is the incoming result of a pattern network where the output is a float or scalar value.
Filename
The input/output filename of the resulting baked texture.
This parameter is required.
Atlas Style
Formating style for atlas textures. When enabled, the filename must contain _MAPID_ which will be substituted automatically according to the surface parameterization.
| Value | Example (texture_MAPID_.tex) |
|---|---|
| None | texture.tex |
| UDIM (MARI) | texture1001.tex |
| UV Tile Base-1 (Mudbox) | texture_u1_v1.tex |
| UV Tile Base-0 (Zbrush) | texture_u0_v0.tex |
UDIM is only defined for textures with U values in range 0.0 to 10.0 and V values greater than 0.0. Users should avoid negative texture coordinates for all atlas texture workflows.
Filter
Selects different reconstruction filters that can be used during texture lookup. The available filters are:
- Nearest
- Box
- Bilinear
- Bspline
- Mitchell
- Catmullrom
- Gaussian
- Lagrangian
Mip Interpolate
Interpolate values between mipmap levels, resulting in smoother transitions between levels.
Invert T
Inverts the T parameter for the texture lookup.
Missing Color
Resulting color when there is an error opening the texture file.
Bake Mode
This mode enables or disables texture baking.
Render Mode
Control reading from input patterns or baked textures during regular renders.
| Value | Description |
|---|---|
| Automatic | Attempts to first read previously baked textures, else the input pattern. |
| Input | Always reads from the input pattern. |
| Texture | Always reads from previously baked textures, else the missing color. |
File Type
Output file type display driver such as txmake (.tex), OpenEXR (.exr), and TIFF (.tif).
File Format
Underlying formats for the txmake (.tex) file type: OpenEXR or TIFF
Data Type
OpenEXR data type: half or float.
Compression
Compression for OpenEXR file format: None, RLE, ZIP, or PIZ
Resolution X and Resolution Y
The resolution of the baked texture. Higher numbers may preserve more details at the cost of memory usage. For best results, use a power of two.
PrimVar ST/S
This parameter chooses the 2D or 1D primvar that defines the texture manifold.
PrimVar T
This optional parameter chooses a second 1D primvar that defines the texture manifold.
