Mel/Python command for saving GI maps?

[jbvfx]

Hi

What is the command for saving the irrandiance map and lightcache map to file?

Regards,

For the irradiance map, assuming that the map is in memory, the MEL command is

vray giMaps save irradiance "fileName.vrmap";

for the light cache, it should be

vray giMaps save lightcache "fileName.vrlmap";

Best regards,

Great. Thanks Vlado.

Is there a documentation for the vray mel commands? It would be cool to see what other "hidden" commands vray has.

Unfortunately, no (although you can look at the UI MEL scripts that come with V-Ray; they contain examples for usage of all the commands). They were mostly created for our own internal use... Nevertheless, I'm collecting a list of the most useful commands, hopefully we'll upload that on spot3d soon.

Alright.

On another note.. Is it possible to ignore the render region in the VFB when using the 'vrend' command? So that it always renders the full image when using the mel command even though render region is enabled. Or alternatively a mel command for unchecking the render region button in the VFB?

Nope. This is the same command that is used to actually do the rendering (region or not) when you press the various buttons in the Maya UI. It is not a separate command just for your convenience

Or alternatively a mel command for unchecking the render region button in the VFB?

In the latest nightly builds, you can use the following command:

vray vfbControl -setregion reset;

Type

vray vfbControl;

to see other commands related to the VFB.
