Cannot open renderer description file "-mrRenderer.xml"

It's not very frequent that this terminal rendering error comes into the support or happens at all but it does happen and it will leave a few people scratching there heads.

Well, no need to worry at all.  This error is very minor and it will show up because a user has somehow overlooked at what command they are sending.  It really only takes one character to be out of place.

Below is the example we usually see.

Render -r -mr file.ma

If you look carefully,  there is a extra hyphen being used.  To fix this just remove the hyphen just before "mr".  The "-r" is the only valid flag in the above example and the render will fail because what follows is not a valid string to go with the flag.

So the correct command would be.

Render -r mr file.ma

small user error but does get missed by some folks.

I was left scratching my head by this same error, even though I'd just done a simple:

render -r filename.mb

with no options at all. I'd been wondering what that seemingly unnecessary "-r" option was for, so left it out, for a simple:

render filename.mb

which worked perfectly!
