AccuRender nXt

advanced rendering for AutoCAD

Roy,

I have a model I did earlier in the Nxt development that is a pretty big model. You may remember it was a living community built on a oil platform (called Seastead).

I pulled it up over the weekend, segregated the lights onto logical channels (the channels were not in the builds at the time I was working with this model).

I then tried to render using the path tracer. It ran for about the first pass then crashed my Acad to the desktop without any messages or warnings. I then ran it on the original particle tracer and it runs fine. Is there a limitation of the number of lights you can use (or should try to use) when using the path tracer that is different than the original rendering engine?

Shouldn't be a lights issue.  If it's 32 bit it's likely an address space memory issue.  The two engines can have different memory requirements.  If it's not a memory issue I'm very interested in the model.

I would say that as well but this was on my home machine and it is a 64 bit OS. It is Vista but has never given me grief to this point. Got a quad core processor (I'm not sure of the clock speed).

I rebooted my machine and started only acad and Nxt and it did the same thing.

It is a big file but I have worked with much larger files with no problems (it's about 28 Meg).

I'm interested-- upload it if you're willing.

Sorry for the delay. I forwarded the model. Hope you can figure out what is giving me issues.

I lied when I said it was totally mine. I forgot Ted Kyte donated the awsome generator.

"Yeah-- I understand.  I just think you may find you have a similar problem in this new engine with trying to estimate how many passes will be good enough.   That can vary a lot. You're always going have some error, allocating…"

"It's an easy feature to add, but I'm pretty sure with this new version you'll find a time constraint to be more reliable.  The rendering below is probably done already, with a noise filter, or close to it."

"I suspect it will take a lot longer without the noise filter. These similar renders ran for 5 minutes each. nXt performed 127 passes and Studio performed 344 passes. Incidentally, is it possible to set a render running to a certain number of…"

"Reliance on the noise filter does concern me a little. A lot of my work involves wood grain and fabrics, both of which can have varying degrees of texture which affect the way light is reflected. With the noise filter off, are renders likely to take…"

"Yes, that works now, though a bit glitchy. Dragging and dropping materials doesn't work (is it supposed to?)."

"Found it-- it's not working properly if the palette is docked.  For now if you drag the AccuRender Studio palette and make it floating everything works.  I'll see what I can do."
