Hello, I'd like to ask a question, can i consider unity as my render engine for both high and low poly models? instead of v-ray , arnold...etc ?
You should be using teh Octane Renderer, honestly. Octane is the prefered renderer for many studios, and now it is available in Unity. https://unity3d.com/partners/otoy/octanerender
Yes You can totally render high level models and graphics in Unity!!!Sorry i'm late to the band wagon on this topic. But here is a in-engine render *Unity* I did this with my laptop and my laptop is 8 years old no fancy graphics card.
