rendering problem - render completion render goes black

[blink_image]

I have a major problem with Autocad 14 rendering. I have a scene that I am rendering (using the sky environment and medium/high settings). The rendering seems to proceed OK, but upon completion, the whole screen goes black apart from a square in the bottom left of the window that seems to show just a portion of the sky. The render took over 17 minutes.

Please see the attached image. I need a solution to this asap. Has anyone seen this before or can anyone help?

Hi,

>> The rendering seems to proceed OK, but upon completion, the whole screen goes black

Looking to your screenshot the rendering was not finished at all.

The progess-bars havn't reached the right end.

Same thing happens to me. It's not finished because it stops.

At least I am not alone.

Hi,

Without any message in the commandline? Press <F2> to get the window with more lines of the command area just to make sure there is really no message or any tip about why it stopped.

I have not seen that the progressbars didn't go to end, but rendering stopped (except I press <ESC> during rendering).

When it happens to me, and has happened to me several times, what I usually do is inspect all my model objects, auditing and check for duplicate objects

(duplicated data in blocks), after correcting those errors I can finalize the render...

Hi Henrique,

Is it reproducable? Do you have (or does anyone have) a sample for me where I can see that phenomen?

Hi Alfred,

right now I'm not at home, but later I'll try to find a sample and I'll send it to you.

Cheers

Same thing happens, Render it's not finished because it stops

“The rendering seems to proceed OK, but upon completion the whole screen goes black apart from a square in the bottom left of the window that seems to show just a portion of the sky”.

My complex render took between 3-5 hours on my Laptop S55-A5279, Intel Core i7 4700MQ 2.4GHz, RAM 12GB, Nvidia GT 740M 2GB.

 Please HELP.                                                                                                     -Mario-

Hi Mario,

the only advice I can give is the same advice I have posted at message #6

When it happens to me, and has happened to me several times, what I usually do is inspect all my model objects, auditing and check for duplicate objects (duplicated data in blocks), after correcting those errors I can finalize the render...
