Please help! Problm facing in walkthru

[ravi_chawda1981]

Please help me out!

I m doing walkthrough and i m facing many problems:

let me describe u step by step,

i)flickering-i've rendered some images(in targa) and run in premeier but its not looking smooth! there is flickering moment

ii)Time-The another headache is, it is taking a hell lot of time! i ve good configuration(4 GB ram+ 512 graphic card) Pc so there is no machine problem! I m using Irrdnce+QMC with medium preset and 0.005 in rQMC sampler noise threshold. the time taken by one frame is 25 minutes(Now this is big one! what say?)

iii)and at last but not least the QUALITY! the quality is not good enough

Hereby i m showing u two images one of walkthru and the other one with still image setting!

is this a camera animation only, or are there animated elements in the scene?

[ravi_chawda1981]

no just a camera animation

Ohh ! also there is RPC moving people

[STRAT]

are you using a camera animation mode? are you pre-caching your solutions?

i'd use LC for your secondary bouncing, this means you can pre-cache the solution and save render time.

 

if you pre-cache the irradiance map you can incrementally save it at every 15 frames, at half resolution (no AA needed). you then can pre-cache the LC for the whole animation and half size too. these should render in a matter of minutes for the whole animation. imo, rpc aren't up to a professional standard anyway.

 

then at final render time just use the pre-cached solutions in the gi slots. All you're doing in essence then is raytrace rendering.

 

you should always use the right animation mode, always pre-cache, and always optimise the scene settings for greatest speed.

 

if you're just setting up the ir settings, the qmc settings and hitting render, then you're doing it wrong. it'll take a long time and it'll flicker.

 

 

 

\edit

 

for the sake of animated rpc people, i'd either take them out completely, comp them in later, or eliminate them from the gi calculations. which ever, just for some rpc peeps, i dont think it's worth the time effort and hastle setting up your animation for full object animation rendering.

I ve already used Irrdnce+Lc map but when i render using the irrdnce map and Light cache map the image doesnt come proper i.e; it looks darker! also i dont understand how can i used the pre-cached irrdnce map saved incrementally. Pls describe

[WAcky]

also precaching will most likely eliminate flickering. How about taking out alot of the items for testing's sake and try out the workflow described here

[STRAT]

yes. follow spot3d tuts. i'm from a vray for c4d background, so i dont know the exact max procedures i'm sorry

[ravi_chawda1981]

thnks!

the tutorials are really very nice!

it will be helpfull for me!
