Flickering In Fly Trhough Animation

[JCM ARQ]

Hello guys, maybe some of you ca help me out, i will appreciate any comment, I'm rendering a 5 minute fly through animation of a moreless big model (a park including various buildings,theater,lake, trees,ecc.),exteriors and interiors. I have already rendered practically everything, and in general its ok. Except for the first 30 seconds, where i get a very notorious flickering around. Where it shows de most its in a zone where i have a theater (its seen from far, and it has alot of shadows blinking on it).

 

I'm using Max 9 , with vray 1.50, about my settings,:

I'm rendering a 720x576 at 30 FPS,

Primary bounces with Irradiance map, and secondary with Brute Force. Image Sampler DMC, antialiasing filter Catmull Rom (it worked well in general, but I tried as well blurry filters like area, soft, video...without success)

The Irradiance Map with preset MEDIUM-ANIMATION, having first a an animation prepass and then animation rendering.

 

In this part of the movie I'm using a single Direct light with Vray shadows.

 

I have already made several tests in order to minimize the flickering (according to what I have read in the forums), but i have not get the result I need.

I have tried with softer filters for the antialiasing, calculating the irradiance map with multiframe incremental, also incremental add to current map (every 10 frames) and then rendering with this...

I took out the texture map of the material (leaving only color). But I still get the flickering (the softer filters and calculating the irradiance map every 10 help a little, but it still shows) .

I have tried as well rendering with HIGH-ANIMATION preset, but the problem keeps appearing. I check for double elements as well.

 

I'm attaching the settings I'm using in general and a pic showing where is the problem in case its helpful. Also the settings of the light.

 

If anyone has any other idea it will be great.

 

Thanks in advance

I don't think a 50/20 split on the IRR settings is enough, bump this to 80/30.

Also, try a the "summed" filter in the material dialog box, see attached. Hve you tried a Brute Force as Primary? Look up universal settings in vray and tweak as you like.

Thanks Cesar, I tried changing those parameters, together with other changes (the blurry filter in the dmc, some changes in the lights, ecc.) and I got a better result, I'm still getting some kind of "radiation" effect, but it seems to be acceptable for the moment (the one I got before was really too much)... I'll keep tryng and will see what happens
