Do you have a crash with the sample scene available in the .zip file?

Hi Juanjo,

yes it crashes when updating GPUS

Oliv

Here it works fine, no problems so far. Are you sure that you have not changed anything in the scene, or do you have any other problem with the plugin?

Are you using the x64 plugin?

Anybody else can test the sample OpenSubDiv scene to see if it works?

-Juanjo

Works fine here.

Just opened and tried with ipr then rendered.

No problem

Yes, i'm using the X64 plugin
and the sample scene hasn't been changed...
IPR and F9 crashes
For the moment everything else works fine.
The only strange thing i noticed (but may be it's the normal behavior of it)
is the displacement maps exploding the polygons when applied to other things than a simple plane,
like if the polygons where not attached to each other.
For the opensubdiv, is there an error log somewhere that i could send you?
Thanks

Yes please, enable the log file in the plugin options panel and send it to me.

Are you sure that the objects with displacement that explode the polygons have the vertex welded?, can you post a screengrab or a sample scene?

-Juanjo

Ok i updated the drivers of my graphic cards with the last version
and now the opendubdiv works fine

For the displacement, below is what i get when i apply
the mountain displacement to a sphere (all points are welded)
Thanks again for your help

You need to enable the smoothing parameter in the Ligthwave material. Without this parameter enabled the object doesn't have the Lightwave normals and the displacement doesn't work.

Thanks very much Juanjo!
