Render Not Processing

Hi all,

I am a student and am using Sketch-up and Irender. This has been working fine up until now. When hit the render button, the geometry loads but then when it goes to the render screen, it just stays blank. I have left it running overnight and is still blank in the morning (refer to attached screen dump).

Any insights as to what is causing this? I have tried running this with Sketch-up Version 8 and 14.

Thanks

Michelle

This is might be something that we have already fixed.

Could you download the latest version that we've posted and try that on this model? You can download it here:

Hi Rich, thanks for your response.

I have tried this latest version and earlier versions. This error occurs on both. I have managed 4 renders on different sketchup files prior to this happening. Originally thinking this was a file size issue, I made copies of the sketchup files in order to render particular rooms in a smaller file having deleted and purged unnecessary scenes/components etc. Could it be the sketchup file with the issue, not the Irender? I have been attempting renders for 2 days and have lost extremely important time with the presentation date looming.

Regards, Michelle

Can you send me the file, so I can try to render it on a couple of machines?

Please can use this link to send it to us:

There rendering did finish for me. Here is the info from the Statistics dialog from the Rendering window:

Extraction Time: 16 minutes 28.0 seconds
Loading Time: 52.0 seconds
Render Time: 6 hours 56 minutes 37.3 seconds
Passes: 20 (AR: 20)

Geometry:
Meshes: 90320
Faces: 1024054
Materials: 157
Lights: 91
Material Illuminance Lights: 20911
ArPlants: 0
RPCs: 0

I suspect the 20,901 lights created by a material set to have illumination is what is causing it to render so slowly. If a material is used as a light source (Material Illuminance is set for the material) and that material is on a surface that gets extracted into thousands of individual faces, then you end up with thousands of individual light sources.

If you can determine which material is being used as a light source, and turn that off and use a real single light to replace it that will probably speed this rendering up quite a bit. I tried using the Light Query/Edit dialog to see what material might be the culprit, but that light search is taking forever...

The Light Query routine finnaly finished.

It looks like it's this "<auto>" material on the Teardrop Multi Pendant that making so many lights.

I wold turn off the material illumination for that material, and then use Obect Properies to make the whole component a single light, or edit the component and make each pendant a sub-component that could be a simgle light, or just simply place a single light bulb inside or around each of the pendants, whatever would be the most efficient thing to do.

Hi Rich,

Sorry I'm only just getting back to you. Thank you very much for your help. In the end, I just deleted those pendant lights and things went much faster.
