Im rendering 1 frame, to test the image quality later…
However i dont see that bar that says rendering (image 0 from 1 lets say).
I checked the file output path and there indeed exist an EXR file and another one of type: MANTRA_CHECKPOINT File.

In the down left corner of Houdini it says however 4:32 (Press ESc to Cancel) mantra_ipr frame 2 *right arrow* Rendering image.

Why don't I see graphic approval that my image is rendering I should be seeing it. When I check file output EXR, it says 1 kb and MANTRA checkpoint file 0 kb. It is not updating, is it even rendering it?

Whats the problem I don't get it, help anyone?

It looks like a bug in Mantra that the pop-up progress display doesn't appear for a single frame.

It's not a bug; it allows one to continue working while the render is in the background.

The render scheduler pane may be used to pause/kill single frame renders.
