Have you seen if your Graphic card is compatible
"Light Tracer can run probably on any GPU produced after 2013 (please download the latest drivers!)."

Thanks Pilou
my graphic card is : AMD Radeon R9 M395X 4 Go graphismes on iMac (Retina 5K, 27 pouces, fin 2015)
but it's not a matter because i use keyshot 9 for professionnal renders and the great free Blender for for speed render with EEVEE

So maybe try the Discord Light Tracer!
https://discord.com/invite/7gAsv9q

New version! 1.6.5

giving it a try now it seems really slow and did not import all of the formats i thought it could...anyway lets see, maybe it might
be done 'later' ;o)

What is the best 'not too expensive' renderer for moi3d users in your opinion Pilou?

My 2 favorites are the free Real Time Render SimLab Composer Lite ! (max 1980*1040 )
https://www.simlab-soft.com/3d-products/simlab-composer-lite.aspx?utm_source=free_tools

Super easy : accepts quasi all 3D formats (except 3DM from Moi so take OBJ from Moi)
So you can import and mix many different things!

And the Free TwinMotion 2019 - 2020 without any limitations - terrific simplicity and such vegetations wind, snow, ocean animation's camera etc...
( free if you had downloaded the 2019 by Epic Games) who is even more easy if possible!

Another one! For the Moi SPK exported models ! ;)
A free version is existing!
https://www.coohom.com/

No render online...
Bella Render Free in 1280*720 Integrated in SketchUp, Rhino, Maya or in Standalone
https://bellarender.com/

For the moment for the OBJ import you have to put all the files on the same path level! Mesh, Mtl, texture... etc

CadRays is also cool!

I've never heard of this render farm before, so far, I've been using https://rebusfarm.net for the longest time... which is why I was going to recommend it here, if you get the chance you should check it out too, they really have one of the best render farms I've seen, really fast and really affordable.

Can maybe useful! ;)
Not sure it is in the free Web version... (verified...it's not! :(

Not exactly a render but...
CGDream

https://cgdream.ai/
Free 20 images / Day, 1024 x 1024
252 Filters (5 maxi), 5 enhances / Day
import 3D GLB, FBX (so moi3D!!!

Filter Sc-fi : 1.00


Vizcom same prompt, (very complex colored transparent engine)
6 renders engines 100%, same start image (CGD), last 4 Refine, 90,50,3,10 %



But Vizcom can make the same : import a 3D object directly inside and render it!

Vizcom free + import volume 3D OBJ (from Moi3D) :)
A prompt + an image as style!

Thinking of getting light tracer.
I use blender but light tracer seems faster....when you are a one man show ...every minute counts :D
