Frosted Glass for Animation

[flyinhawaiian]

True...

I thought you didn't ask for compositing tricks, rather for a non-flickering, and similar look to, your low subdivs frosted glass - in camera -.
Pushing it further into compositing and matte painting sure opens up possibilities, but is it really a time saver?
How much time is spent to learn/apply such techniques, rather than upping subdivs in the material and render out with the knowledge it'll work?
Unless you're having that glass covering the whole image, the impact can't be that hard.

Relatively true today. What with the processors getting cheaper and faster by the minute. If you've got a decent farm and enough time to render, by all means, do dial in the settings. (And of course, wide use of the jury-rigged solutions some of us have mentioned opens up a world of hassle if you're ever unfortunate enough to have to revisit the hacked-together scene. ) I actually first used the "matte painting" method I mentioned earlier to paint over troublesome shadow bleeds back in the Lightscape days, when you spent 15 hours calculating a lighting solution on a project that was due the next day. There just wasn't time to re-render the solution. So, yes, it does seem to be getting a bit dated of a technique. It's just another option on the list of desperation ploys. Do with it what you will.

Personally, I'd follow lele's suggestion and render the crop. Then, I'd set my favorite image/sequence viewer to "loop" and dial in the settings based on the amount of noise I notice in the looping sequence.

Well - I've hung Respower (the renderfarm) quite a few times this week and ran very low on time for client deadline. They're running on x32 Vray 1.5 SP1 - their OSs are not setup for x64 which I found out after I signed up...

As I've had to kick out the animations, the quality is going to suffer - glossies throughout the entire scene had to be turned off.

My scene is compromised of a room surrounded by glass walls - the middle section of the glass had a large frosted panel running all along it.

Respower kicked out errors after getting close to the frosted glass and render times skyrocketed. Even after optimization, many frames hung on their machines. I've ended up having to run these portions of the animation internally - the quality isnt as good as I wished but the deadline approaches.



So for future reference, is there a better way to obtain a frosted glass look? Do you suppose the vray2sidedmaterial would be better to use in this situation???

try a finely tiled bump map instead, might get away with that. and certainly wont flicker.
