Hello.

I started learning Houdini not too long ago. Watched a lot of tutorials, but newer tried the rendering.
So i watched the basic lightning and rendering tutorial from the learning section.

My problem is that MPlayer not popping up if i hit render.
My scene is just a simple grid with a sphere with basic lights (point & env), basic material clay.
I tryed the mantra and mantra - PBR nodes, but nothing happens. MPlayer is not popping up automaticaly, after manual launch and forcing it to listen the renderer, i cant get a render.
Flipbook is working fine. So i checked every options in the mantra node , every tooltips and i readed the mantra online help. Still cant get a simple render.
Ok. I watched a few video tutorials from youtube and vimeo.

If i try to render my camera gives back an error:

Error saving geometry for : \obj\grid_object1\grid1

and after trying to render the camera always jumps back to 0,0,0 and clears rotation.

I tried to render out other scenes from the net, but no render

Tried the render view, only black vew. cant see anything.

oooook.
Reinstalled houdini and the whole OS. Still no render.

houdini version : houdini-12.5.615-win64-vc9
VGA driver: NVidia 331.82

I hope someone can halp me to solve this irritating problem.

Thanks.

Can you share your scene please?

Ok. I downloaded the tutorial files and if i import the assets i can render out this scene. but if i want to build something from a new file and try to render nothing happens.

in scene view down below the flipbook icon if i right click on the output icon and i choose the View:Mantra option im getting this error:

4812: Fatal error: Segmentation Fault

and Houdini crashing out.

The original poster this type of error:

“Error saving geometry for : \obj\grid_object1\grid1”

I have found this is usually because of low disk space. Mantra may need to save some temporary files in order to render and if the drives are full it can't do that to render. I got the same thing recently and cleared off space on the drive and it no longer returned that error. Hope that helps.
