Render Artifacts

[ethan]

Serious artifacts while rendering last night. Anybody know how to get around this or what might be cuasing this?

Using tg 2.2.23.1

Thanks.

I get this all the time 
Its memory related and the only solution I have found is to use smaller texture images, smaller GeoTiffs (my main problem), lower the AA and Detail settings (including atmo and cloud settings) and drop down the GIrd and GIsq. Basically the renderer has run out of memory so you'll have to drop all your settings down and gradually build them up again till you get an acceptable result. Also try dropping the octave of your procedural textures, a difference of a few octaves wont be that noticeable but may make a considerable difference in memory usage and render time.
Hope this helps a bit ...

Thanks for the details. Will give it another try tonight.

Out of curiosity what is the upper safe memory limit for TG these days? I know it will go to 4GB but at what point below that does it start to wig out?

What about the possibility of rendering in crops?

Hi ethan,

here is a good thread about memory and TG2, though it is a Mac thread, its content is not Mac specific:

Dude, I just went throught this same problem a couple of weeks ago.  You can view my own query and subsequent solution here: http://forums.planetside.co.uk/index.php?topic=11706.0

Long story short.  It's RAM related.  Increased the physcial RAM on my computer and used the /3GB switch.

Ethan, I thought you were one of our alpha testers? Get yourself the 64-bit alpha. It's pretty stable If not, drop me a line.

Can we  PM you too Matt?






Sorry, Matt   But hearing this made me happy! It looks close to final as it sounds?

Strange, this happens "all the time"? I've never seen such odd color result; usually if the renderer runs out of memory it reports errors and stops rendering. In any case if it's really memory related and you have access to the 64 bit alpha, that's the obvious solution.
