Convert PTEX to TIF

Verified by Adam B.· reviewed by FE Editorial ·updated Aug 22, 2026
QUICK ANSWER
Is it possible to convert PTEX to TIF?
Yes - PTEX converts to TIF.

The cleanest route is Houdini's Bake Texture node set to the UDIM unwrapping method, which turns Ptex data into UV-mapped .tif maps. Mari can also export a Ptex channel as .tif, and ptxconvert in.ptx out.tif handles a single-face file.

Also to TIF: RWL · ARW · PCT

Why convert PTEX to TIF?

People convert to .tif because Ptex only works inside a few renderers, whereas a UV-based .tif is a lossless, high-bit-depth map that most engines and pipelines accept. The conversion re-projects the per-face Ptex data onto standard UV tiles.

How to convert PTEX to TIF

SideFX Houdini PAID

Use the Bake Texture render node, set the UV Unwrapping Method to UDIM, point it at the Ptex-textured geometry and set the output image to .tif.

Foundry Mari PAID

Open the Ptex channel and use Export (or Export Flattened), choosing .tif as the format to write a standard UV image.

ptxconvert (Ptex utilities) OPEN-SOURCE

Run ptxconvert in.ptx out.tif for a single-face file; the reverse (in.tif out.ptx -mode periodic) needs power-of-two dimensions.

Quality & what to watch

  • Baking requires a valid UV layout on the mesh; without one you must unwrap first, which changes how the texture is stored.
  • The output .tif is a fixed resolution, so Ptex's adaptive per-face detail and seamless filtering are flattened away.
  • ptxconvert only converts single-face Ptex; production multi-face assets need Houdini or Mari to bake.

Frequently asked questions

Which tool gives the best Ptex-to-TIFF result?
Houdini's Bake Texture node with the UDIM method is the most direct, producing UV-mapped .tif tiles from the Ptex data.
Do I lose quality baking Ptex to TIFF?
You keep bit depth if you use 16-bit TIFF, but you lose Ptex's per-face resolution and seamless cross-face filtering at a fixed map size.
Can I convert a TIFF back into Ptex?
Yes for a single face with ptxconvert ... -mode periodic, but the TIFF must have power-of-two dimensions.
