Thanks a lot for the detailed explanation. I've been using lightroom myself over the last couple weeks and its amazing how much more efficient it can be than using just photoshop. I used to do post on every render individually, whereas now I can just create a custom preset in lightroom.
Since I'm not the games artist (I do the writing and post work), I have virtually zero knowledge about octane, and the learning curve seems pretty daunting compared to iray. But I think it's about time I bite the bullet and finally start learning. Also, can I just ask what the reason was for switching over to octane, and any advantages or disadvantages you've noticed between the two?
