A Problem

[darthvader]

As you can see, there are some sections where the leaves are not being rendered. Since they are cut off in straight lines I was  thinking it was some sort of GI issue. Would my assumption be correct and how could I go about fixing it? thanks

Hi,

This looks it could be a problem with population rendering. What version are you using?

Regards,

[darthvader]

this is from the beta

What are your system specifications, how much memory do you have? It might help to change cache size, or reduce the number of threads used for rendering if you have a multi-core CPU.

Processor: Intel(R) Core(TM)2 Duo CPU T7100 @ 1.8GHz 1.8 GHz
RAM: 2GB
System: 32-bit Operating System

I tried changing the cache size (both up and down) from the default 400 mb but it had no effect. Also reducing the number of threads had no effect either

[Oshyan]

You tried "max threads" at 1 (or 0) and had the same effect? Can you check memory use while rendering? I presume you are getting "population counter" errors in the error window?

- Oshyan

[darthvader]

nope, no population errors, but reducing the maximum threads to 1 seems to have done the trick

thanks

[Oshyan]

Interesting. You didn't get any errors but still had this problem?

- Oshyan

[darthvader]

not a single error, which really surprised me since I thought this sort of thing would flood me with little red octagons of sorrow.

[Oshyan]

Very surprising. It might be interesting to look at this scene if it's not too difficult to package up. You can send to support AT planetside.co.uk with an attachment size up to 20MB.

I appear to have spoken too soon, the same problem has come up again in my current render so I will zip the file up (except the bushes because they aren't having problems...and they make the zip too big) and send it to support

...red octagons of sorrow.

Lol. Is that the official name? Beats blue screen of death.

[darthvader]

Something to indicate that it isn't a problem with the program is that when I got rid of the model that was experienceing the problem and replaced it with another tree the issue disappeared.

[Oshyan]

Thanks for the additional details and scene files. Although it may not happen with other objects, it still may be an error in TG2's handling of that object, rather than an inherent problem with the object itself.

I probably got the same errors during the rendering of my last scene, but here it seems to be a problem with GI and the small low-level clouds.

My system:
Processor: Intel(R) Core(TM)2 Quad CPU Q6600 2.4GHz
RAM: 4GB (3,5 because of Vista32)
Windows Vista Home Premium
