I've just have my first experience with render4you using Corona render.
A very basic video, 2078 frames in HD, a complex metal structure, but basic materials.
Guy at Render4you gave me a great support, I've just had a little problem during first test, immediately resolved (I was using no light source but env colour, Corona env colour. The renderfarm has returned all black, maybe for a bug in 7.2 alpha (?) so I switch to Max env colour and we resolved.)
The cost preview (using web site) was not really very near the real cost, but maybe my test was made on some lucky frames... , anyways it was a good price. And after a cup of test with a few frames, I preview a cost very very near the final cost.
Queue time was very quick, and we renders all the frames in less than 6 hours (my ws need about 2 minutes for frames, that means 70h).
Interface is easy to use and all steps are documented. I mean, this is a "for dummies" renderfarm way.
So, my feedback is absolutely positive, thanks Sven for your support during all steps.
