Hello Karsten!

@You : "...use it by Blender. Well integrated...Very slow..."

Every time a put again my hands on Blender I understand how badly I misjudged it.

OK. It's true. Its Cycles rendering engine is not the fastest of the market but with a powerful GPU (for example my 1080 Ti) it has very good results.

And mostly, I think it is a sort of "Swiss Army knife" into the world of CG.

For example, when it comes to rendering or applying a post process elaboration or dealing with textures and mapping, it is very difficult to find a task that can't be performed by its powerful node editor.

In fact for the moment, although my knowledge of Blender is pretty limited, actually I'm testing it exclusively for rendering purposes and
for what I'm seeing so far its Cycles engine it's very good both in terms of performance but above all in terms of quality.

And the fact that it is TOTALLY free...well...it's a game changer :)

Not fast as Thea Render but undoubtedly much more versatile.

Ciao!
