Sponza AR 2.5 mins a Frame

Recommended Posts

Check youtube for others go at this classic 3D render test. Cannot find videos of the actual structure, You may think 35 hours !! But it is a real test for global illumination with the only light being from the open top. And there are some very smooth ceilings so artefacts are a problem The trick is to stop it looking CGI with some depth added and atmosphere. That I will work on next. As i said earlier 2.5 mins a frame when we would be looking at 10 mins + for a good still render..so I am quite pleased. Gonna really punch it out with some added lighting and the god rays The blotchiness on the right upper ceiling is due to the reflected sun light from the floor a really hard thing to calculate and get right but it is stable..I will look at getting that fixed in post perhaps with another render just for that section of ceiling, but it should not be too smooth, like the left hand one, as the sunlight will have an effect, just not so blotchy.. I can separate those polygons out for the render but still have the full building give the GI indirect lighting so should be a relatively fast render. I will do that with an alpha so i can just composite it onto this existing render. Watch in HD full screen to lose the flicker

What render engine are you using?

 

With eevee this quality could probably be done with about a 3 sec. per frame render time.

Looks like with the CryEngine they did it in real time.

    It's an impressive time for AR.  AR is way slow compared to other options now a days.

    I was not trying to start one.  Sounded like you wanted a fast render with some GI.  Wanted to let you know of your options out right now.  Unreal Engine with an RTX card has real time ray tracing with GI.  U Render has a really good way of faking GI and could probably also render that scene with a decent or good look in real time.

  • But AR and me goes a long ways back. We've kicked each other senseless many times but I kinda love AR..and it is there with the kit so anyone stating out has to get a handle on it. If I was doing this for a dollar, there is lots and lots more to do with this scene, I would not mind unloading that to a farm. I am just comfortable with AR..And that is just another way of saying I do not have the dollar to get any better !!

     

    Another reason for the long render was as a stress test. You see my rig is in a poorly state and I want to get into a long fun project and to take a break i decided to render this out to make sure my rig would cope. The water cooling radiator is hanging out like it's lungs are out. The fans on the GPU are failing. But not a whimper on that long render. So the rig will see me through and I can get on with a scene I am doing for a tutorial

     

    I set that scene up in 2014 I think. Going through old old files and sadly having to delete old friends that will not play with me any more. I, like  many others, got the Sponza bug years ago. It was a standard scene to learn on at one time. So to be honest I may well revisit it and adjust the GI. I am wondering if I can just do it for the problem areas and composite. Yes I must play with Sponza some more..it is very calming

  • i could object matte the problem areas out and use that as a mask for post work in fusion ?

    Why go through all that work when Blander with eevee is free and probably will work even with your old system?

  • I am a C4D acolyte,Sometimes i am not bothered with render time. I get a "what if " in my mind and start playing. Once I have seen if it can or cannot be done I move on...it is not professional but then neither am I
    If i had the render capabilities in R6 I have now I would think I was tripping. I am in that time frame now..Very pokey StarDawg at the moment. If i had the render capabilities in R6 I have now I would think I was tripping. I am in that time frame now..Very pokey StarDawg at the moment.
