Hello I simply graduated from structure and want to give attention to my Rendering. I need to strive enscape and lumion (as a result of it’s person pleasant) however that is the one gpu I’ve and I dont have the cash to purchase for a brand new one. If i might get outcomes, I’ll market my expertise and purchase a brand new rtx or gpu.

I’ve additionally tried utilizing twinmotion however i can solely obtain a cartoon-like outputs. So i switched again to vray

This are my renders utilizing vray.
Can somebody level out the way to enhance this renders, as a result of sick keep in vray until i get the cash to purchase for an rtx. Thanks
