Well looky there, you are indeed correct!  I hadn’t noticed that it was missing there.  But then again, I don’t use the scripted mode much.  It could be that the scripting engine needs the files in specific places in order to do its job.

Could be, but judging from the scripts, I’m not sure this is the case. The scripts simply implement two passes needed to generate the point cloud first and then render. The only hindrance I can think of might be the standard “collect and localise” subroutine in DS not being configured to recognise the .ptc as one of the files that would need to be collected… but to test this I need the docs.

The raytracing engine in 3DL was improved drastically in the 10. series.  There was an issue where starting up had huge overhead.  That overhead has been completely removed and the raytracer can now start pretty much immediately.  Also, the speed of the tracer itself was improved.  According to reports, it should now be faster to use the raytracer than the shadow maps.  I have not personally tested this as I don’t normally use shadow maps to start with.  Now, on to your question… I haven’t tried the GI mode in 4.5 yet.  I guess I should.

If only we could convince DNA to get on the GPU assisted wagon.

Thanks for the info! I should transfer that scene into 4.5 and see how it fares. I generally don’t like raytraced shadows because they require a softness percentage to look more natural, and those softness calculations used to be a real performance hog as well, but if that has been dealt with by chance, I might consider using them more often - especially for larger scenes like landscapes, where DSMs can get unwieldy with higher sample rates and a lot of detail in the scene.

...I wonder if blurred raytraced reflections are now faster. So many things to test, so little time…

As for GPU assisted rendering… I guess they will take advantage of this, in due time. From what I’ve heard, and correct me if I’m wrong, GPU acceleration is not that widely used in film industry yet, and isn’t 3Delight primarily geared at movie studios?

 

Yes, the movie industry is indeed one of the biggest users of 3DL.  However, “The Avengers” used a Realtime GPU assisted 3D rendering and motion capture for the work on the Hulk.  3Delight has been the “Go To” for the Marvel series and it looks like 3Delight may have been left out of the loop here.

GPU stream processing REALLY speeds up raytracing.  Massively parallel processing allows for a ray per stream to be actualized.  If one has 1024 streams (like on some ATI cards) that is 1024 pixels at once.  The trick is the linking process between CPU/GPU and management of GPU Memory resources.  Current unbiased renderers load all of the textures as well as the geometry into the GPU memory, hence requiring a large amount of memory to be available or the reduction of geometry or textures.  There is work on going for a more effective use of the GPU.  Here’s a quick overview… For instance, in a general scene, the ratio of rays that impact a specific object’s bounding box is relatively small.  In a portrait, less than 25%.  So if the GPUs are used to preclear Viewport LoS (line of sight) collisions with bounding boxes (returning booleans) then the CPU can create a tree of areas where actual processing needs to be done.  Then the CPU feeds those regions into memory and sets the GPUs loose to create base texture mapping.  Next a reflection bounce collision tree is computed.  Once this is done, one can load the lights and compute luminosity maps, execute dynamic radiosity and adjust surface brightness accordingly.  The final step is to apply LoS reflectivity.

@mjc1016 : could you post the specs of your pc and what you used as a graphic card and also what’s really in the scene and you render settings and resolution please? It’s difficult to have a real idea with just your pictures

The latest 3DL is indeed very quick and It never needed more than 1 hour since the engine update. Even tried some scene with raytraced reflexions, volumetrics, SSS and other things. By the way, did you notice the UE GI and indirect light now work better?

Btw I’m on windows and the standalone with 2 cores is slower than the internal with 4 cores.

Athlon 64 x2 4400, 4 GB RAM. GT 430 1 GB running Slackware64 13.37.

The scene consists of V4, the hair (Erriene), the lace wrap (a simple plain draped in Blender with a tiled shader/lace pattern…Fabricator preset) applied, a plain as the backdrop and 3 lights. (DzAmbient shader light with AO on, a ‘standard’ spot as a key light, it’s the shadow caster and a distant light for fill.

I haven’t done much rendering in 4 since I updated to 4.5, so…no.  I’m needing to do some promo shots for an item I’m packing up, so I’ll be doing them tonight, I hope.

Current unbiased renderers load all of the textures as well as the geometry into the GPU memory, hence requiring a large amount of memory to be available or the reduction of geometry or textures.  There is work on going for a more effective use of the GPU.

LuxRender’s Hybrid mode implements something along the lines of what you describe.  It does not store textures in GPU memory.  It generates bundles of rays to trace, hands them to the GPU to do the actual tracing, and then based on the results applies the texturing in CPU-space.  The thing is, the CPU<->GPU interactions are kinda slow (and I get the impression this is a hardware thing, not a software implementation thing), so on ‘simple’ scenes, it’s actually SLOWER than CPU-only rendering because of the overhead passing things back and forth between CPU-space and GPU-space.  To see a benefit from the GPU, you need a scene with complex geometry.

Now, Lux’s hybrid modes are also still not really ready for prime time.  Hybrid Path mostly works, though there are some features that it doesn’t support (like instances).  Hybrid BiDir still has some serious issues, even by the Lux dev’s own admission.  Since the official Lux 1.0 release a month or so ago, they’ve started doing work to unify a some of the code between CPU LuxRender and the LuxRays library (their GPU library), so hopefully that will help clean up some of the problems with the Hybrid render modes.  (E.g., LuxRays is missing some of the NaN and other numerical exception handling that CPU LuxRender has.)

finally got around to trying this again. I tried a few days ago but it wouldn’t save the render file. Only had time to troubleshoot that today. (windows7 was protecting the directory)

Anyway I’ve got a quadcore and rendering out of Studio is still faster but the standalone still has it’s advantages. simple scene but here is the score

Studio 4.5       1 min 33 seconds
Standalone     2 min 17 seconds + 9 seconds for studio to create the rib

So the standalone is impressive! for only two cores it was very close to the quad core performance. I will probably use the standalone to render batches of images since it will allow me to step away or work on something else.

I’ve been converted.

EDIT: I take that back for now. I don’t have time to troubleshoot unfortunately so I’ll have to stick to my system of using studio. I compared the standalone render to the studio and there are noticeable differences in some of the materials. Also I can’t seem to get the batch render to not overwrite the same file. I thought the filename in studio would be how the standalone would name things but everything keeps getting named render.tiff. oh well

I just downloaded the free standalone 3Delight and am trying to render a scene, but I don’t think anything’s happening. There doesn’t seem to be an actual “application” just a .dylib file. I’ve tried following the instructions in the user manual, and in the thread from the old site, but all I get in the “Terminal—bash” window is “Michael-Tramperts-Mac-mini:~ TrampGraphics$. No render window, nothing.

I did a standard install. Am I missing something? Is it rendering? What’s the deal? How do I use this? I’m on a 1.83 GHz Intel Core Duo Mac Mini running OSX Snow Leopard.

On the Mac the use of 3Delight is a bit “unconventional.”  First, you will need to output your scene to .rib.  You do this via the “Advanced Render Settings” tab.  You will need to use the Command Line (or Terminal) in order to use the 3Delight renderer.  It cannot be done via the GUI.

You will need to “cd” to the location that you output the .rib file.  Once there you will execute the “renderdl” command to actually start the renderer.  There are several options that can be set via command line flags that you may or may not need to use depending of what you desire to do.

I made the RIB file and used the terminal. The above Terminal—Bash window is the only thing that comes up.

I’m not sure what you mean by ““cd” to the location” though.

You will need to note the path that you used to save the rib file.  Once your terminal is up you will type something like:

cd < path you used for the .rib > <enter>
renderdl -q -id <filename>.rib { this is if you want to watch the render proceed.  slower than not }
or
renderdl -q <filename>.rib { this will not show a window }

when the command completes, you will have a file called “render.tiff” that contains your image.

The “<” and “>” are not used.  They were there to delimit where you put variable information as opposed to verbatim information.

Also, spaces will need to be prefaced by a backslash “\”.  So here would be “correct” versions of your commands:

cd /Users/TrampGraphics/Desktop/RIB\ files/
renderdl -q -id First\ Trick\ or\ Treat.rib

Do not use “exit” after the line.

Open a terminal, and type the command “pwd” and hit enter.  Send the results to me.

The “<” and “>” are not used.  They were there to delimit where you put variable information as opposed to verbatim information.

Also, spaces will need to be prefaced by a backslash “\”.  So here would be “correct” versions of your commands:

cd /Users/TrampGraphics/Desktop/RIB\ files/
renderdl -q -id First\ Trick\ or\ Treat.rib

OK, I retried and it seems to be working, though wth a lot of “ERROR” messages coming up, but the path doesn’t seem to be using the file inside of the First Trick or Treat_Collected folder, which contains all of the .tdl files.

Here’s what I got when I did the “pwd” command:

cd /Users/TrampGraphics/Desktop/RIB\ files/
pwd ; exit;
Michael-Tramperts-Mac-mini:~ TrampGraphics$ cd /Users/TrampGraphics/Desktop/RIB\ files/
Michael-Tramperts-Mac-mini:RIB files TrampGraphics$ pwd ; exit;
/Users/TrampGraphics/Desktop/RIB files
logout

I just downloaded the free standalone 3Delight and am trying to render a scene, but I don’t think anything’s happening. There doesn’t seem to be an actual “application” just a .dylib file. I’ve tried following the instructions in the user manual, and in the thread from the old site, but all I get in the “Terminal—bash” window is “Michael-Tramperts-Mac-mini:~ TrampGraphics$. No render window, nothing.

I did a standard install. Am I missing something? Is it rendering? What’s the deal? How do I use this? I’m on a 1.83 GHz Intel Core Duo Mac Mini running OSX Snow Leopard.

On the Mac the use of 3Delight is a bit “unconventional.”  First, you will need to output your scene to .rib.  You do this via the “Advanced Render Settings” tab.  You will need to use the Command Line (or Terminal) in order to use the 3Delight renderer.  It cannot be done via the GUI.

You will need to “cd” to the location that you output the .rib file.  Once there you will execute the “renderdl” command to actually start the renderer.  There are several options that can be set via command line flags that you may or may not need to use depending of what you desire to do.

I made the RIB file and used the terminal. The above Terminal—Bash window is the only thing that comes up.

I’m not sure what you mean by ““cd” to the location” though.

You will need to note the path that you used to save the rib file.  Once your terminal is up you will type something like:

cd < path you used for the .rib > <enter>
renderdl -q -id <filename>.rib { this is if you want to watch the render proceed.  slower than not }
or
renderdl -q <filename>.rib { this will not show a window }

when the command completes, you will have a file called “render.tiff” that contains your image.

OK, Tried that. and these are what I get:

when trying the cd, I get: Last login: Wed Oct 24 18:21:26 on ttys000
cd</Users/TrampGraphics/Desktop/RIB files/First Trick or Treat_collected/First Trick or Treat.rib> ; exit;
Michael-Tramperts-Mac-mini:~ TrampGraphics$ cd</Users/TrampGraphics/Desktop/RIB files/First Trick or Treat_collected/First Trick or Treat.rib> ; exit;
-bash: syntax error near unexpected token `;’
Michael-Tramperts-Mac-mini:~ TrampGraphics$

when running the Renderdl, I get:
Last login: Wed Oct 24 18:21:26 on ttys000
cd</Users/TrampGraphics/Desktop/RIB files/First Trick or Treat_collected/First Trick or Treat.rib> ; exit;
Michael-Tramperts-Mac-mini:~ TrampGraphics$ cd</Users/TrampGraphics/Desktop/RIB files/First Trick or Treat_collected/First Trick or Treat.rib> ; exit;
-bash: syntax error near unexpected token `;’
Michael-Tramperts-Mac-mini:~ TrampGraphics$

OK. Change the “cd” to be the following:

cd /Users/TrampGraphics/Desktop/RIB\ files/First\ Trick\ or\ Treat_collected
renderdl -q -id First\ Trick\ or\ Treat.rib

forget that the “exit” command exists.  If you need to close the shell use ctrl-d.  BTW, spaces are evil.
