Hi,
I have a simple doubt what the difference between mantra -H host1, host2…
and mantra -n 2 rendering commands…
If I have 4 machines connected with LAN which command I have to use for network rendering….
Thanks,
mantra network render

mantra -H machinename,machinename2,machinename3 (no spaces)
-n will still work, but is the number of threads per machine. Note that in H12 this doesn't work as expected however (SESI is aware). Basically, I have an 8 core machine, and if I use -H on the local machine plus another 12 core machine, only 8 cores get used on the remote machine. You'd expect “use max cpus” to use 8 cores on my local machine and 12 cores on the remote machine for 20 total.
FYI, -H across multiple machines brings diminishing returns depending on how heavy your scene is and how fast your network is. Never use it for sequences of frames as that will be extremely inefficient. It's useful for interactive lighting sessions however.
Caveat: This is all Linux based info, YMMV on Windows/OSX as I've done little to no testing on those platforms.
Cheers,

The ifd bakes in the paths for all textures. You can use a text editor such as vim (use cream as it is vim with a standard gui) to view the ifd file and inspect the texture paths in amongst all the binary data.
If these paths are not valid on the remote hosts, then your images won't show up. Pretty simple.
The advice to use unc paths only works if those remote render target machines have the root machine mounted with the same name. With unc paths, you need to mount the other windows machines with the same machine name and then use the path syntax:
\\ComputerName\SharedFolder\Resource\…

Yes it makes a tremendous amount of sense to create your shadow maps exclusively without generating an image.
With shadow map generation enabled for your light(s), create a dedicated ROP Output Driver for shadow maps (just a normal ROP set to Micropolygon rendering).
In the Properties > Render tab, disable the “Create Image From Viewing Camera” toggle render property.
When you hit render, only the deep shadow map is generated.
