File naming

All rendering processes output image or data file, which location is set by default when you create the pass. The location can be changed in the Pass > File Pattern attribute of the pass.

File name specifiers

The file path of a pass can be a combination of several specifiers, such as the frame number, the pass name, the stereo eye, or any environment variable.

The specifiers are:

• $f - The frame number without prefixed 0. It will be replaced by 1, 2, 3, ..., 101, 102, 103.
• $0xf - The frame number with x prefixed 0. "$03f" will be replaced by 001, 002, 003, ..., 102, 103.
• $e - The eye number, where 1 is the left eye.
• $E - The eye name (that is "left" or "right").
• $c - The camera name including prefix
• $C - The camera name excluding prefix
• $l - The pass name.
• $L - The pass name stripped of any reference prefix.
• $o - The output name (ie. AOVs for RenderPass layers).
• $n - The parent output node name (ie. RenderLayers for RenderPass).
• $x - The default file extension.

For instance, let's consider a RenderPass named "render", which contains:

• render
• hero
• Beauty
• Diffuse
• Specular
• set
• Beauty
• Diffuse
• Specular
• IndDiffuse
• Reflection

The pass file pattern is "$(IMAGES)/$l_$n_$o.$05f.$x", and the environment variable IMAGES is /tmp/images. The following files are generated at frame 1:

• /tmp/images/render_hero_Beauty.00001.png
• /tmp/images/render_hero_Diffuse.00001.png
• /tmp/images/render_hero_Specular.00001.png
• /tmp/images/render_set_Beauty.00001.png
• /tmp/images/render_set_Diffuse.00001.png
• /tmp/images/render_set_Specular.00001.png
• /tmp/images/render_set_IndDiffuse.00001.png
• /tmp/images/render_set_Reflection.00001.png

You can force the specifier to be in lower case by inserting an underscore just after the $ of the specifier (ie. $_o).

Default file naming

The default location is, for each type of pass:

• RenderPass: $(IMAGES)/$l_$n_$o_$e_$05f.$x
• Bake2D: $(IMAGES)/$l_$n_$o_$05f.$x
• Compositing: $(IMAGES)/$l_$o_$e_$05f.$x
