I have been able to import an environment and create realistic lighting rather quickly by using the power of GPU rendering. Paired with its ability to create instances of geometry, it makes it easy to render a megacity environment in half the time. One issue with this is the clutter that can be made with connecting nodes.
TurboCAD is well suited to a smaller budget, it is by no means the best there is but for the money, it fills the gap. Being an AutoCAD & DraftSight user I find the user interface a little old and the lack of common drafting industry shortcut keys a bit of a hindrance. However this product, TurboCAD gets the job done, other packages like DraftSight do not even come with an active 3D option on the cheaper end, standard license whereas TurboCAD does, even though it's a little clumsy to use.
Octane uses GPU rendering so it takes advantage of the video card.
It gives you a good selection of options to tweak and refine your model rendering.
It can use 3D instances so it doesn't overuse computer resources.
There are plugins that can be incorporated into other 3D packages for rendering.
Octane is particularly inexpensive compared to other 3D render packages.
You are able to copy certain sections of nodes in order to create different iterations of the same environment or model. For example, changing the lighting or camera features.
TurboCAD does all of the things we need it to do and some. The wide variety of options to create specificity in each of our projects is a large plus. The reason it was given a 9 is because the learning curve can be a little steep and sometimes certain processes are not as intuitive as they could be
Although both have their pros and cons, Octane is far less expensive and it allows for more control over the geometry within a scene with better lighting and camera controls.
