I'm running it on a 2014 retina iMac, which is a reasonably fast mac machine, and I find it to be slower than iRay (CPU only rendering, since my card is AMD). My test scene (1 naked G2F with no except the environment IBL and hair) has been running for over 25 minutes and still hasn't converged. I think the default convergence is different between the two (higher by default in reality, I think), but I think this same scene would have taken 10 minutes or less with iRay. That's with "Extra Boost" turned on.
Folks have reminded me about the openCL issue which means my experience with openCL not working is true for all mac users and isn't expected to be fixed until apple fixes it on their end.
I'll test it later on a more complicated scene that took hours to complete in iRay, but I suspect I'll be sticking with iRay and keep my eyes open for a cheap way to add cuda support in the coming months.
luxrender renders forever, there is no preset stop conditions like in iray.You stop it when you like what you see.
cpu only test image
edit: I forgot to mention this is on an 8 core AMD with 7 threads running, for only 2min 25 sec ( see the graph at the bottom of the image)
Well, I finally bought it (Poser version)... I waffled for a moment and then I saw it had at least one "car paint"... I had previously thought there was no car paint shader, but it seems there is now. I still haven't set up Poser on my new Dell, so I'll guess I'll have to wait to see how that looks.
Tried accessing ANY page on his website. Still getting the server error notices. Tried on Cyberfox and Edge Browser. Same thing...
Just read on the Runtime site that Paolo says it is not necessary to uninstall as long as you install in the same location as 4.0. So I guess from the horse's mouth .... fingers crossed. :)
Before I installed 4.1, I had a folder in Plugins that was called Reality, I renamed it to Reality2, but I had endless problems with 4.1 not working at all.
I finally removed the Reality2 folder from Plugins and stored it in a temp folder, now it all works as expected.
I downloaded from daz since I bought reality 4 there. Looked for it in product list and it said 4.1, Did a manual download. I tried his website for 5 hours and got errors.
Cool ice still waiting
I can understand these issues. But this is a repeat. Paolo should have known that this was going to happen again and should have had a solution in place.
I'm trying OpenCL with LuxRender 1.5 and Reality 4.1. All I get is a black screen. Seems to work with CPU.
Lux has always had problems with hybrid or GPU as long as cpu is somewhat faster. Delphi I agree. Hence why I am delving more into iray..
i just bought reality 4.1 and i am just baffled over the incompetence regarding information about installing and registering reality 4.1 software...i get server errors and i cant register it, therefore cant use it...NO info ANYWHERE about how to go forth step by step about these things, not even here on daz studio page, this is weak! i pay so much money for all kinds of stuff and this is...omg i cant describe the frustration, now if there is no solution to this i want my money back, the poor information "thing" is showing elsewhere too...
Did you manage to get it installed?
I had to try several times to get mine to register as well.I tried a few times when I first installed it.Then waited about an hour and tried again and it finally went through.
Perhaps this product should have been labelled Reality 4.1 Beta release because it doesn't seem to have gone through to the final or release stages of software development. Not by a long shot.
more tools... cool
As it seems I was lucky I just downloaded, installed, registered and now I am rendering...
Don't forget to set one camera and one light or you'll get the error message box.
After getting distracted rendering NVITWAS I finally went back to the Preta and managed to get the update. Installer is a little fruit loops, but at least you get to pick where you want to put stuff, even if it does spring a silent sub directory. I have come across something strange though. When I call Reality from DS I get nothing. I check, and DAZ does know where R4.1 is, so not sure what's going on. I am able to launch Reality from the .exe and it seems to communicate properly.
Anyone else get this?
Great suggestion but my only purchase of Reality was 1.25 and it's still only offering that version. All day I was out of the house because it was too darned hot to be inside so I come back all these hours later and his servers are still slammed. Grrrrrrrrrrrrr
Well, the installer I downloaded was actually an installer extractor, it created a folder with the actual installer, in my case 'Reality_DS_w64' and inside it it was a RealityInstaller.exe.
So in GPU mode, you need to let it render for several minutes before it shows anything on screen. But in my case, the first time it tries to show something on screen, it resets my video drivers and luxrenders appears to continue to work, but it's clearly not doing anything anymore. So that pretty much makes luxrender and reality useless for me for the time being.
edit: Ah you know what? I got something to render in GPU mode with another scene, but it's using the wrong camera. It's using the perspective camera. That's probably what was wrong with the other scene. Still, this is kinda bad.
edit2: Actually no. It's rendering from a strange POV that isn't either the perspective camera or Camera 1. There are no other cameras in the scene. Very weird.
Hmm? Oh, yeah, I got that archive thingy too. No, that's all fine. It's installed. ;)
So... my download and un-registration and re-registration of R4.1 was painless. Worked instantly, no bugs.
From what I can tell, there's a few adjustments in terms of how LuxRender operates. It seems to render by regions or chunks instead of the whole thing at once. I'll post my test renders in a bit.
I was getting some very strange camera related issues when I was playing with R4 the other day in anticipation of 4.1. I think it turned out to be the "frame width" in the camera paramaters. if it is anything other than 36, try resseting that. ...To 36.
Okay, I'm getting strange results with R4.1: I'm getting a weird outline-like region when I try to render something that's highly exposed with a very abrupt dark area... weird. Never got this effect with the old LuxRender, and this happens with or without CPU boost.
@mtl1 - That's just freakish. Have never seen that, but looks like today is a day for freakish events :)
This was meant to be skin. I'm trying to recreate a scene I just did with Iray, and things are freaking out! That lady is meant to have skin.
Edit - I'ma going to let this render - when taking in the whole scene it looks like Dali having a baby with late 80s experimental CG.
Hi Jim,
I figured out the problem: Distant Lights don't seem to play well with Reality 4.1. I remember them being a little better back in the old 4.0 version but I could've been mistaken. It looks like that the distant light is boosting the lit regions too much while not playing nice with shaded areas.
I replaced the distant light with a spot light, adjusted the direction a little and this is what I got. Much softer shadows. (or non-existent shadows, haha). Please excuse my poor composition and over-exposure in my renders. :P :)
Up next is mesh-lights and a comparison with iray.
edit: Oh, I should add that this is around (edit again: 12-ish) Samples per pixel, which is *quite* low for Reality/Luxrender renders.
A few more: First one is Reality 4.1 (spot converted to mesh with bidirectional light paths) and the second one is iray. I didn't put too much work in these renders -- that was the whole point. I simply put figures in and wanted to see what each renderer would give with minimal tweaking.
A couple things should be obvious: the skin in iray is softer/matted -- possibly due to the skin being better optimized within DAZ -- but the lighting and shadows in Reality are *much* more accurate.
@Jim It's set to 36. Even in CPU mode, it's using a camera angle that is not in my scene. It does this for several of my scenes (ie. all of the ones I've tried so far).
I still cant d/l it what BS
I've gone to the rdna site where the forums seems to be the official place for this plugin, especially to report bugs. Based on my personal experience and what I've seen over there, this product is a mess. Now, if they could fix the half dozen critical bugs that people are encountering, wouldn't be so bad. But right now, it's just not ready. The CPU rendering is quite amazing if you can get it to work though. Extremely fast.
