Yeah...But leveraging that against the typical revenues of a job / time saved I think it's a valid purchase ;)

Hi Marco,

I plan to compare Octane vs LuxRender standalone both in Linux version, so I am curious to know the results :-)

Ciao

Hello Marco,

yep it's a snail, but the only way is to use a physical renderer, if you want to test the look and feel in some applications. Target isn't a beautiful Rendering or photorealistic Rendering - more a realistic rendering in the meaning of a Simulation. e.g. optical Systems. So everyone has a different Point of view.

Have a nice day
Karsten

Oh yes Karsten!
@You : "...different Point of view..."

You're right.

In fact for me the key feature is the speed rather than photorealism :)

Have anice day.

Hi Mik,

thanks for the detailed response. I think the trick with rendering larger images and then reducing them in pixel size afterwards
helps also to reduce the aliasing issues and not only getting rid of fireflies, without using the filter, because it should give the
render engine "more room" to draw those areas. At least, i remember this from long time ago when reading about render tips.

Best regards
Stefan

Hi Stefan.

@You : "... think the trick with rendering larger images..."

Yes, undoubtedly in this way you can get a less pixelated final image but at a cost of much more render time.
I you render a frame at 4K resolution and then you perform a scale down to a FullHD res, for sure you
will get a better looking image but the initial render time is increased by 4x!

If the time is a key, this method is not good at all.

You can get better results in terms of time and also, is some circumstances, in terms of quality,
if you use a software like Affinity Photo or others to apply a post process effect to the rendered images.

Furthermore...I've tried also the (now official) "Denoising" feature of Blender 2.79 and in many circumstances it can offer great improvement to the final render at a cost of a small fraction of increased time (about 20%).

Ciao!

Hi everyone.

Just in order to close an open discourse...

After many considerations and tests I decided to get rid of the trial version of Simlab Composer Pro.

This was the third time I've given this software the chance to be included into my current pipeline,
but another time, and this time is the last time, I understood that this product makes no sense to me, now.

As I said I've invested my money into a "consumer" but powerful GPU (1080 Ti) and Simlab is CPU bound.
Furthermore its material database library is not better than the one I have with Thea Render,
and for all other "rendering things" I can leverage on Blender with its GPU Cycles engine,
and Blender can offer tons of features and is totally free.

If I decided to invest my money on a powerful multicore CPU (Ryzen or Threadripper or i9) rather than a GPU, maybe I could have given to Simlab another chance.

Have a nice day to all and thanks anyway for suggestions :)

Ciao!

Hi Marco,

> If the time is a key, this method is not good at all.

I prefer quality over quantity and if i need super duper fast renderings
i can use a french Supercomputer... :-)

Since this is a rendering tips and tricks thread it would be helpful for the general audience if you could
show us an example (original with some aliasing and one reworked with Affinity Photo).

Best regards

Hello,

has someone tested CADRays?

- Karsten

---

Hi Karsten,

I hadn't heard of CADrays yet, thanks, I'll check it out.

Also interesting is AMD Radeon ProRender. Fully free and supported by a number of 3D editors, including Blender and Maya. It uses OpenCL, so it utilizes rendering power of both CPU and GPU.

Hello Metin,

thanks for the link!
565MB download for the ProRender for linux. There was a time that a rendering tool fits to 3 3 1/4" disks with 1.4MB ... okay 25 years ago!

Hi Karsten,

if you are looking for a small (Windows) production renderer maybe the famous japanese Redqueen
Renderer is something for you. It requires editing text files, in order to use this little and fast render
engine.

https://github.com/shinjiogaki/redqueen

and some gallery images:

Stefan

Hi Karsten and Stefan,

Karsten: Yeah, good old times when everything fitted on a few diskettes. :) Amiga rules! :D

Stefan: Wow, Redqueen's results looks great. It's a pity that the coder won't update it anymore, because he's employed by Solid Angle, creators of the Arnold renderer.

Hi everyone!

Instant Light (realtime render engine), an amazing companion for Moi and 3D-Coat, has been updated to 1.5.11 stable beta!

On my Gtx 1080 Ti it has superb realtime performance.

Hi,
There is a standalone or only plugin for C4D and others ?
Thanks

---

Hi Finema.

Actually it's a standalone software.

It's a specialized package for GPU bound realtime unbiased and biased renderings.

---

ha yes !
I don't find the link to download it on the site.
That's run on Mac ?
Thanks .

---

Hi Finema.


Here's where you can download the latest official beta

https://www.instantlightrt.com/try-buy.html

Click on "Download Official Release Version 1.5.11" and you will be redirected to their Google Drive

Just keep in minds these things :

1) after downloaded, for a correct installation run the installation exe as "Administrator"

2) The internal code of this software uses the DirectX 11+ routines very deeply so in order to get full access to all low-level optimization
you must run the software in Administrator mode ("Run as Administrator")

3) This realtime render engine it's very powerful but has a "non standard" UI, a little bit strange.
Follow the basic tutorials on their Youtube channel.
Once you learn the foundation and its philosophy then the fun begins :)

4) Instant Light pushes your GPU to its limit and it requires a powerful GPU.
From Gtx 900 series and up you should get very good performance.
With my Gtx 1080 Ti this software is amazing.
On my laptop with an old Quadro K3100M (768 cuda and 4GB of ram) it's only "sufficient"


Hope this help.

Ciao!
