Rendering on RenderStreet can close that gap, though, as every project is being assigned to the hardware that offers the best performance. Renderman does not sound interesting to me at this time.

Appleseed works with its own materials and textures. When the gathered data from millions of such rays is combined, this results in a complete image. In order to achieve full Blender integration with real-time viewport updates, OctaneRender comes with a custom Blender build that is frequently updated by OctaneRender developers OTOY. So after all i deleted it and wrote it to their forum. For example, Pixar's great Renderman renderer is free for non-commercial use, but the Blender add-on hasn't been updated to be compatible with Blender 2.8. You don't know what some people can make out of it, if they have tools on your computer which are always online.

If i make "non-commercial projects" the available Renderers are perfect for everything. http://www.lilysoft.org/CGI/SR/Spectral%20Render.htm. Grease Pencil; Sampling; Light Paths; Volumes; Subdivision

James Siewert – The monthly plan suits my wallet a LOT better, Once with Eevee on the specially-configured render nodes available for Eevee rendering on our farm, Finally, in Cycles on the standard GPU render nodes available for Cycles rendering on our farm. POV-Ray is also a free Renderer and it produces Raytraced images means they are free of any noise. Although it is essentially a commercial product, OctaneRender is available for free with the limitation of being able to use only one GPU in case you own multiple GPUs. Like LuxCoreRender and Appleseed, Yafaray is an open source project, and is still actively maintained, although it seems to be a relatively obscure renderer when compared to the previously discussed renderers.

it doesn't seem to work correctly. A noGo for me.

The Cycles to ProRender material converter is integrated and works at the touch of a button. And this wastes resources. Until the nnot. The third example is an outdoor scene created by Andreas Strømberg. Cycles is natively integrated in Blender, Poser, and Rhino. Appleseed is an interesting, potent renderer capable of realistic results, but its main limitation is that it is purely CPU-based, making it not the best choice if you've got a competent GPU in your system. Appleseed while it says that it can make caustics, can not render real dispersion in colours at this time. currently do not have such a active development like Luxray. Introduction; Render Settings. A more advanced renderer is recommended for that, such as Blender's Cycles.

especially - but not only - because of its extensive Material Library which is included (but need you to run a separate Setup-Program). The gap is increasing with the scene complexity because Cycles gets slower as the scene becomes more complicated. This way, the two versions of the scene have exactly the same setup in terms of geometry, materials and lighting. Blender's Workbench is the default viewport renderer. It will possibly be interesting 2021.

Also, for really convincing results Eevee can be a bit cumbersome to set up with its many render settings and shadow options. Sample:

The second real alternative is Luxrender and the Picture from Sharlybg shows where it has its strengths. AMD Pro Render has already quite some unique features that make a difference to nearly the whole competition. And for bounced light and convincing reflections and refractions you need to fiddle with Irradiance Probes, Reflection Probes, material-level options and cache pre-rendering. We know everything there is about rendering, budgets and deadlines. This causes a number of differences between the versions of the same scene – some of them are subtle, some of them more obvious. The most important two are, of course, “how fast is it?” and “how does the output quality compare to Cycles?”.

Rendering with the Workbench is basically rendering a screenshot of your 3D viewport. With things like light tracing, caustic cache, light groups and so on Lux is simply the best render engine for architectural renders, especially interiors.

At the time of writing, some more free renderers are available for Blender, but those come with limitations. In practice you will only notice this in specific situations where light calculations are complex, such as dark indoor scenes with only one light source casting light through a window, or a scene where caustics are prominent, such as a swimming pool or a close-up shot of a glass on a table. For example, Appleseed is more capable of rendering detailed caustics than Cycles. Again, when moving the Cycles render to our regular GPU machines, the difference drops to Eevee being only 2.4x faster for the same image.

Circling back to the questions from the beginning of the post: yes, Eevee is fast. However Mitsuba - theoretically a good thing - is outdated. For example when using the CPU and the GPU's for rendering, Pro Render will make all of them just work "on the same tile". D5_Render leaded to a Facebook-Page and from there i could not find a way where to really get it.

Radeon ProRender is particularly interesting to Blender users working with macOS, because unlike Cycles, ProRender fully supports Apple's Metal graphics library, taking advantage of that to accelerate rendering on macOS systems.
