Hi Finema and Pilou.

Thanks for help :)

Ok.

I've made some considerations.

1) The "Lite" version is not good for me. 1920x1080 is too small. I need "print" resolution (at least A3 300 dpi 3508 pixels x 4961)

2) I'm evaluating the "Pro" version.
During the next days I will test it.
But for sure one thing that is not very good for me is that SimLab is CPU bound while some times ago I've invested my money in a powerful Gtx 1080 Ti,
and I've not invested in a multicore CPU. I have a good i7-7700K.

Actually I already have Thea Render, a blazing fast CPU+GPU rendering engine.
I need a rendering engine that should allow me to use this particular superspeed workflow for rendering of 3D concept models :
I don't want to waste my time in Retopo/UV/Texturing.
I need a rendering engine that should take the exported obj models with mid/high poly count and simply applying premade materials over them and render in one shot.

With Thea Render I can already do this thing with good results.

I want to see if the rendering quality of SimLab with that particular workflow is sufficient for me.
If so, I will accept its "slowness" of CPU bound and I will get a "Pro" license.

I will let you know.

Thanks and have a nice day.
