IRender freezes at "Starting Raytracing"

Hi all,

Whenever I try and Render a large model (and sometimes even with smaller models) It gets to the point of "Starting Raytracing" then freezes. I've even left it overnight and still wont budge. I have also tried rendering straight through the 'batch' file and still get to the same point. Ive tried purging the model and using simpler components because of how large the model is but still get the same result. Is there a way I can work around this or could it be a computer issue?

Thanks!

Could you send me the smallest model possible where this is happening for you so that I can try it here, to see if it's something in the model that's causing this? You can send it to me using: http://www.renderplus.com/wp2/uploads/

I sent the file thanks again. I'm thinking the model is just too big. If so is there a way of simplifying to reduce the size or is it a lost cause?

It is huge. I had to stop trying to render it. It was taking too long just during the first step of saving the data for the rendering, and slowing down my machine too much.

I'll try it on another machine where I can let it go and see if it ever finishes.

I don't know how to make it smaller, except for the trick of using images instead of components for things that won't affect the final image.

I checked in and the file had started rendering. I'll check back in tomorrow and see if it renders anything.

I notice that artificial lights are turned on and that we think there are 572 light sources in the model, so if it ever does start, it will render vary slowly.

Thank you so much for all the help I really appreciate it. Ive started simplifying everything and ill try deleting all the lights to see if that helps. Thanks again!
