Maxwell Render

Hi guys,

Updated version 2.7. Since then the rendering will not progress after a certain time.
It will just show "waiting" under "Next SL" and "Update". But "Time Passed" does go on. The "waiting" message will just hang there for hours and nothing will appear. I tried 2 different scenes, one hangs there after 3 hours (Sl 12) rendering and the other an hour (SL8). Anyone experience this? or there are actually a setting to solve this?

Im using Windows XP 64 bit, Lightwave 11.0.1.

Thanks.

I've moved this question to the main forum, since it sounds like an engine issue and the core developers don't check the Lightwave forum that often.

Thank you Mihnea for a fast reply.

Hope to get a solution really soon. (Think i might fall back to 2.6 to be safe, worry it will happen on my final render)

Just another update, using the same second scene again to test and now it reaches SL10 without hanging but i suspect it will at a later time.

Regards.

Another Issue.

Adding Displacement map will crash Lightwave.
And if it doesnt crash, maxwell render will not proceed to render at all.

I can't reproduce this. When exactly does it crash, immediately after you select the image file, or when you render? Does it crash with any texture, or a specific file?

Hi Mihnea.

When it was preprocessing before the actual render begins.

The scene was just a few alphabets image map (jpeg) onto a sub-patched object. Displacement was set under "pretessellated". I know it uses quite amount of ram on the start but it crashed at 10GB under the Windows Task Manager indication. My computer has 25 GM Ram so i presumed is more than enough. Anyway i never face this problem before even on a more complex image.

Regards

Aha, so Maxwell crashes, not Lightwave, right?

oh to be precise.

Yes, all rendering crashed under Mawell rendering panel.

And only twice crashed the Lightwave when i tried to update to see the small preview
under the maxwell texturing panel from Lightwave Surface Editor. I think i might have clicked to see the preview while the actual maxwell rendering panel is pre-processing.
I used to do this but never encounter crashes.

We've identified a problem in the engine which occurs when you have multiple materials on the same object, and some of them use displacement. It's not plugin-specific, so it will be fixed in a future Maxwell update (2.7.1, or whatever it will be called).

Thank you Mihnea.

How about the part when the rendering hangs there forever (Brought up at the beginning part of this topic), you guys found the problem? I hope it be resolved as well.

Regards.

The engine guys say it's a known issue, but if you could send me an object which causes it, they would probably be able to find a solution faster. If you have a LWO or MXS which triggers the problem, please send it to mihnea.balta@gmail.com.
