I wouldn’t call this a bug, but maybe more of a “nice to have” feature: if I render an scene with MayaSoft/ mental ray layers with Vray layers, image naming becomes a problem because the default Maya naming behavior is to add a ".’ after the \<Scene\> prefix to separate the frame extension. Vray renders names the file without a separator so **pass\_v27.0001.exr** becomes **pass\_v270001.exr** in the Vray output.

Just put a “.” in after your filename. Vray will always place the number and extension after whatever you type in. So something like

```auto

yourname_here.

```

will output as

`yourname_here.0001.exr`

cheers!
