With the sun at a very low angle, GI on, my rendered scene is blank. With GI off it works.
Try the new build that just came out today?
Yes. And I'm getting counter errors in my grass population...
The scene rendered fine without GI, then I set it up at quality 1, GI, ran it, went to breakfast. When I returned it was finished, after 43 minutes rendering, and utterly black.

Well that sucks! Didn't take you very long to find that one. Perhaps you should be a Alpha Tester?
I think I will wait and see what others find before I install the latest release.
Thanks for reporting it.
Hi Greg,
Can you send me your project? I'll do my best to diagnose the problem. Did you repeat the no-GI test with detail at 1?
Matt
The no-GI test was at .5. I'd built that file in the previous version; Im recreating the scene now from scratch in the latest version. Let me see if this works before I package the old one for you; maybe there was a conflict in settings or something; there are a lot of heavy files.
OK, I'll wait for those, thanks. I asked because was trying to confirm if it really works when GI is off.
I would still like to see the old files even if you get it to work by recreating from scratch in TP4. I don't think a mismatch of settings between TP3 and TP4 is likely to be the problem, but whether it is or not there's a bug that needs to be fixed. I know there are some problems which I am trying to debug using the "counter error" which you saw, so your files may be helpful.
Matt
Ill send you the tgd now so you can look at it; there are a lot opf associated textures and models, so those will have to be collected.
Matt did you get the file?
I'm rendering now in the recreated file and it seems to be working okay so far; I'll know in a few minutes.
As a quick test try rendering a scene with settings at default, but drop the sun to -2 degrees altitude.
Here are results of some tests.
First image: No Raytraced shadows No Enviro Light
Second image: only change is enabling Enviro Light node
I have no idea why the model is half-black either...

That's possibly inverted faces (normals pointing inwards). Might also be double-sided polys, perhaps.
The normals are fine. Its something else, but I don't know what.
Here's a render, same settings, no gi, shadows on, over 1 hour when I stopped it:
This object rendering bug is killing me. (Well my project anyway.)
Greg, are you referring to the black areas on your model, or the GI darkness issue? Do the black areas occur for you on other models?

I'm getting it in my wheat field render. the GI dots run fine but after that it just renders blackness...ment.
Weird thing is, if I did it on the quick render node before I updated to the new version it worked fine. Now it won't work on either.
I haven't tried it without GI to be frank, I'll try it now...................Yeah it works fine without GI.
Does it occur if you disable the objects?
- Oshyan
Still doing it for me. Totally blank on the full and quick render
Edit: I've tried this on GI settings 1, 1, 1 2, 2, 2 2, 1, 1 and 2, 2, 1

Yeah, came thing: the gi renders dots, then clears.
PG did you try to move your camera back a little? It seemed to work for me. Maybe there is a leaf stuck to your lens.
Greg, I haven't received your files. Where did you send them?
Matt
I had it here as an attachment; someone downloaded it, I thought it was you so I removed it.
You guys can try to duplicate the blank render error: set a default scene and move the sun light to -2 degrees altitude. I think that should do it.
I shouldn't make guesses like this, but I have the feeling it may be something up with the light sources (local light sources, not sunlight). Disabling the light source seems to fix the problem on PG's wheat field, although it's hard to prove because it seems intermittent. Literally yesterday I stumbled upon a problem with local light sources which shares some similarities with these. I was in the process of trying to fix it already. I will keep you posted.
Matt

It seems to render fine with these settings here. I get a dusky sky, with dim light and a dark ground, but it definitely looks normal.

Here's the file; the relevant part, the local lights, are in it (the models and textures are too big to collate and upload in the time I have.)
I have the file, thanks. I've just started rendering (Quick Render, with Enviro Light enabled) and it seems to be OK. Perhaps it only happens with the models.

It's not the camera position, I rendered it without GI and it's fine.
Matt: Thanks, getting rid of the light source worked. I only added it because there was a big pool of light on a small patch of wheat that looked odd but it seems to have gone now.
Matt,
I'm packaging the full scene for you now including models and textures; I'll post when its ready. I ran some more tests and it does seem to be the lights; in fact I reinstalled version 941 and am now getting the same problem of patchy black areas when using lights. Strange becasue I was able to render them before and only occasionally get that error...
