New V-ray Irradiance map for animations

[pedro3822]

i´m having the same problem here!!!

 

Can the vray masters help us? how can we delete these white spots, and blows...grrrrr

Without seeing your current settings one could at best only guess what of many things could be causing your problems.

 

are you using the irriadiance map option for "use camera path" ?

 

 

from the help files.....

 

Using irradiance maps for animations with moving objects where the camera also moves - either in Single frame, or Animation (prepass) mode. In this case, setting the Use camera path option on will help to further reduce any flickering, as the GI sample positions on static geometry will not change.

This new method seems interesting, I'm running a test right now,

3 moving objects with motion blur however the camera is static in my scene..., Is this solution for both animated objects and animated camera??

or just the objects ??

Post a render.

Sounds like it could be exposure settings in your case. 'white spots' (aka fireflies) are an easy fix, just check sub-pixel mapping in the color mapping options.

However, without seeing the render it could be any number of issues.

No for those two scenarios you would go different routes.....

 

if you have a moving objects or changing lighting, then you need to go the with the new animation prepass/render methods...

 

but if you only have a moving camera, and everything else is static then you can use the traditional (quicker) methods.

AAaaarghh!!!

 

Bewdy, please submit your settings and some frames, flicker and noise are common problems in animations but are very easy to handle with v-ray. what you must find is the reason: AA settings, subdivisions, noise threshold, and so on.

Hmm, 10k frames - so you're looking at about a 5min clip? Is that 5min where something is moving pretty much the whole time? If that's the case, then you are in for a bit of a wait...

 

There's a pretty good little tut on the new feature here:

What i am getting here from this tutorial is that, this method is fine if you have only animated objects. but he is talking about the animation with moving objects. Second problem is that, I have a scene of about 1400 houses and roads, I am animating cars on it. What i want is, i render from here as image sequence and then put it into after effects. then use Fog 3D filter there to add fog in animation.But if i use the pass rendering method as mentioned in spot3d.com tutorials, How can i get the Z-depth included in the image sequence bcoz after effects's fog 3D filter is used, only if you have the Z-depth pass??

Well, I have done a test or my own scene today. It took whole day for me on Cre2Quad System with x64 etc etc. 4GB Ram.

here is scenario. We have a scene of a housing society with many houses (1400) and traffic. i simply hide the traffic and render the camera animation and saved it as image sequence (backround animation.jpg). then i selected the whole scene (eveything except lights) and in vray properties, i made them "Matte" with -1.0 value and affect shadow and affect alpha (on). and also hide the background (sky image). then unhide the traffic. I turned off the GI. Now the scene is that, whole scene is matted. It will cast shadows, receive shadows and do everything but it will not render as it is matted. now, selected the traffic, turned off GI. Set GI primary to IRMap (high)-- single frame mode. Secondary GI to BruteForce. Render the entire animation sequence as (traffic.png). Note: take transparency or you can use tga sequence as well to get. Now, in after effects, import both sequences (traffic and background). put the traffic in the comp, on above the background layer. The traffic footage should be imported as transparent (pre-multiplied). Thats done! I used this technique. Hope it will work for all of you. Instead of redering 4 times a scene and then composite ot. Render it this way. Let me know what you got out of it in your scene.
