Can you command line render in Houdini??

[afx]

I am on a windows machine and usually when rendering in Maya, I use the command line. I am eagerly making my integration into Houdini, and was wondering if there was anything similar to Maya's render command??

Yes, look at "hrender".

%> hrender -h

Usage:

Single frame:   hrender	[options] driver|cop file.hip [imagefile]
Frame range:	hrender -e [options] driver|cop file.hip

driver|cop:	 -c /img/imgnet
				-c /img/imgnet/cop_name
				-d output_driver

options:		-w pixels	   Output width
				-h pixels	   Output height
				-f frame		Single frame
				-b fraction	 Image processing fraction (0.01 to 1.0)
				-o output	   Output name specification
				-v			  Run in verbose mode
				-R			  Use non-graphics license token

with "-e":	  -f start end	Frame range start and end
				-i increment	Frame increment

Notes:  1)  For output name use $F to specify frame number (e.g. -o $F.pic).
		2)  If only one of width (-w) or height (-h) is specified, aspect ratio
			will be maintained based upon aspect ratio of output driver.

For more advanced needs, you can also pipe any commands into hbatch or run hython and execute ROPs.

For more advanced needs, you can also pipe any commands into hbatch or run hython and execute ROPs.

You can also dissect hrender (though it's ugly) since it's a csh script.

You can also output IFD files (the equivalent of RenderMan RIB or MentalRay MI) and then render form the command line with mantra (Houdini's renderer), without starting Houdini at all.
