This cache can be controlled using the htexcache command line utility.

“temp” will use a local disk cache to store the high performance texture files. “local” will create a high performance texture file in the same directory as the source texture (if possible). Unset or “native”: will use the raw texture map with no conversion This conversion is done once, resulting an overall performance increase. This variable controls how non-ideal texture maps should be used for texturing, automatically running imaketex on these images to create high-performance texture files. The imaketx program can be used to create these high-performance texture files. Some image formats will have better performance when used as texture maps when rendering. This only has an effect if an valid OCIO environment variable is set. With strict parsing, this is not the case. OpenColorIO parsing, “StrawHat.exr” would be interpreted as being in “raw”Ĭolorspace. In this mode, color spaces embedded in filenames mustīe delimited by a period (.), underscore (_), hyphen (-) or space. When set to 3, color space detection will be done with a more strictĭetection algorithm. Set to 0, detection is not performed and Houdini’s native heuristics are OpenColorIO config.ocio file is used (OpenColorIO strict parsing). Way but when no colorspace is found, the “default” role defined by the If set to 2, detection occurs in the same If none are found, use Houdini’s heuristics for determining the colorspace Rightmost string that matches a colorspace will be taken as the colorspace. Enables detection of the OpenColorIO colorspace of an image file by lookingĪt the filename itself.
