i was checking the galleries again. Of course not all are grainy, but whenever there are a lot of plants in the scene, it is grainy. Let me make it clear: It is NOT the artist's ability , it is something wrong in the vue render engine. I followed a lot of tutorials promissing to avoid that grainy look, but it never worked. It might work at very high render settings, that will result in 24h rendering for a 1600 by 900 picture.

Howie Farkes has some scenes with plenty of plants out for both-Vue and Carrara.. Carrara renders look much nicer even with low antialiasing settings.

@ aeilkema:

I like your vue renders. Really cool scenes, but sorry your renders are grainy. You realy know about render settings, so it is NOT your  mistake. Let me repeat. It is in the Vue render engine. I have never seen that kind of grainyness in another render app. You'll immediatly know it is a vue render, when you have a grainy plant scene. I have also seen lot's of renders that were postworked with a blurring tool to get rid of that bad antialiased look. I've tried the same BTW.

Conclusion:

Artists' work: amaizing

Vue features: Best tool for creating worlds - without any real competition.

Vue render - awful for being slow and being grainy on plants
