??? :-\ image says it all. I get the "finished rendering" message, but this black patches remain on the image. Anyone knows what this might be? maybe terragen can't hand so many objects?!?! They around 20 000 polygons each, it's not that many i think.
It starts being really frustrating using Terragen for real life projects with real deadlines :-[
after a fresh restart, nothing opened but terragen, after 17 min of rendering again "finished rendering" message, and again black patches, different this time, but lots of black un-rendered area :/
anyone?
turning GI off (under Enviro Light, Mode: Ambient Occlusion) the render finished, but looks terribly bland...
it seems like a specific model of yours does not have textures. Can you check the texture path and texture filenames and extensions?

That was my guess as well, looks like the black patches have the shape of specific models.
Hmm, Thanks for replying guys. But I don't think that's it. It has rendered in Ambient occlusion and also with just a couple of antennas, and they're the same, only repeated. i'm doing a smaller render see if it works
(http://www.eso.org/~lcalcada/terragen2/chajnantor/noblack.jpg)
it renders in smaller res (1080->600) and quality (detail 0.5 -> 0.35, GI blur radius 8 -> 4).
Also the memory usage seems to be the same, (1.9GB, 2.99GB virtual) on both renders. I'm on a Mac btw...
grrrrrrrr ???

I'm going nuts here. Anyone? :-\
I'd suggest you move this into the Support forum and send PS a TGD along with whatever models you're using. Since Jo is the Mac person, she'd probably be the best person to look at this.
EDIT: And if, as you imply, there is a deadline on this, it would probably help to let PS know what it is.
Things to try :)
Put the objects through Poseray, seems to sort out most of the obj issues:
Check for small displacements especially on your model, unless your getting real close to your objects they will serve little purpose and can cause problems.
Another option might be to export your fully textured object out from TG2 as a TGO object and then replace your obj's with tgo's.
If you like I can look at the file and objects for you pm me if interested.
Good luck

is that a population of dishes or 13 single objects?
This looks like textures are missing...
No I don't think its missing textures, the black squares are not limited to the objects although I do suspect the objects are causing the errors. I suspect it may have something to do with either the objects or (I think) the DEM terrain your using.
richard
It looks like something in your objects (or the object shaders) is causing bad values to be stored in the GI cache (because the problem goes away if you use a different GI mode: ambient occlusion). Can you try re-rendering with just a basic Lambert Shader attached to your objects? If that renders OK, take a look at your shaders and try different settings or shaders to find out where the problem is coming from.

Are the objects double sided? Open them in the program you used to create them. Set the polygons to double sided, then import them back into Terragen 2. Set the double sided checkbox. This may be what's going on. I had a similar issue 15 years ago using Lightwave objects in a 3D game I never finished.

Jo is a he ;-).
Anyway, if you try Matt's suggestions above and don't have any joy, please pack up *everything* which makes up the scene and send it to me. If it's over 10 MB it might not come through via email so you'd need to upload it somewhere and send me the link, if possible. You can email me at :

Ooops! Sorry!
Hi guys,
thank you all for stepping in. At this time I decided to move to plan B, i cannot afford to spend more time in terragen :( so i'll just render the background/landscape in Terragen, and compose the Antennas in Cinema4D, I think I'll get nice results and in a more manageable time. I've spent already too much time in Terragen sorting out stuff, but will try to come back to this eventually to figure out what was wrong. But just to answer some questions here: my objects are already tgo. I've exported them using riptide from cinema, then see that they worked just fine terragen imported as obj, but then saved them as tgo. Re-imported them in my scene afterwards. This is not a population, it's several objects (i needed them to be in very specific spots). And yes, double sided. In the end, it's just weird that the scene renders fine in low quality, but if i increade the image size and quality it goes wrong...
Anyway, once again thanks guys. Will let you know how this looks with my new approach. Cheers
I'm now having the same problem. When I started out with my TG2 scene, everything rendered fine. I have only two objects. When I placed a Reflective Shader (RayTracer checked OFF) at the end of my Terrain node structure, I lost all of my objects to the Black Hole described in this thread. Completely the same - the objects are now outlined silhouettes in black with no textures showing. It doesn't seem to be a memory issue, since I'm only using about 600K of VRAM.
I'll try removing the Reflective Shader tonight completely out of the node structure and see what happens.
Why would you put a reflective shader in the Terrain group? "600k of VRAM"? Do you mean 600MB of RAM?

I get this error it mainly effects the sky :-\
they are so small though its easy just to patch them up in PS but it still needs to be fixed
here is an example
(http://i44.tinypic.com/bdpog3.jpg)
I think yours is a different error actually. The missing sky triangles are something we're looking into.
- Oshyan
the patches only occur when the system is running out of memory because this does not happen when i use terragen in 64bit
I get the black patches, too (Windows XP 64). But, the missing textures on the models isn't related to the Reflective Shader, though that is what I switched before I began having problems.
@Oshyan - see the attachment for interpretive values. ;D And as far as a Reflective Shader in a Terrain Group - this works at the end of the Shader Node network to give the surface a sheen.
Hi Calico,
That's virtual memory size, not VRAM. VRAM is of course Video RAM and is used for graphics.
Regards,
Jo
Oh. Thanks Jo. Virtual Memory, which is Random Accessed Memory.
No, Virtual Memory doesn't specify Random Access Memory (RAM) or not, it's a virtualization system for memory access, allowing for access to memory across multiple systems (RAM and disk-based for example), as well as potentially overcoming issues with memory fragmentation (to a degree). Just stick to Virtual Memory (VM). ;D

I mean this with the greatest sincerity - you're a nerd of the best kind.

Hi all,
well, despite all the problems I kept having with terragen (as i said before, i didn't solve nor did i try to, because i had no time) this is my final image. The background is Terragen (plus PS for color) and then models (GI, shadows) are in Cinema4D. Final comp in PS.

I really like this, shame you had problems in TG, it would be good to find out what was causing them. Did you use a series of mattes for your dust paths to generate the banks and colouring within TG? I have a feeling I might see this image at an aerospace show ;)
Could the image maps for the ground be interacting with the dish objects. If they are, it could throw the geometry off for the dish objects. The trace would hit the inside faces of the dish objects, with their strange, twisted normals; causing the program to render the black patches.
It's only a hunch, but the pics mt_sabao posted reminded me of a game I used to play. The objects would go wacky if the plane of the 'dungeon' was intersected by the players character.
