It is the only tool that I use to create logos. It gives me the flexibility to create sharp text and marks and they can then be resized at will, color changes in a second and perfect way to export. I know that some people use Illustrator for document layout, it is not ideal. While I can easily create documents here, it really is InDesign that is the perfect tool.
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.
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.
While Adobe Illustrator CC is one of the only true design software out there, it really stands heads above the other products. It's clean UI and menu structure is easy to navigate.
There's a bit of a learning curve to this software vs other similar tools that can take some time to learn and get familiar with but the amount of functionality that Adobe Illustrator CC offers is quite large compared to simpler tools.
I normally already know how to do whatever I'm trying out, but the documentation (as well as a simple Google search) makes any question quick to resolve. The Adobe boards themselves are a fantastic resource, especially for resolving questions between new programs and iterative releases.
I chose Rhinoceros 3D because it is accurate to make drawings in it and it is better to make drawings in Rhinoceros 3D and then put them in Adobe Illustrator. But while printing or scaling it is much easier to put it in Adobe Illustrator. This makes the whole printing aspect of it much easier.
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.
