Speeding Vray Animayion..

[shikodesign2000]

Hi,

 

I'm really suffering from relatevily long time for rendering each frame in my interior animation project, though I'm almost finishing it, but I just want to know what things or parameters have to be set to speeding things and let the render time for each frame shorter.

 

I know the following things that have to be not too high:

 

1-Vray light subdivision.

2-Material subdivision.

3-Subd. in light cach.

4-Interpolation and HSph. in IRR map

 

If anyone knows any thing else please tell me.

I would use various renders to produce an anim...that way you can be a bit more flexible.

with vray you have to generate a solution then render all takes time.

render in vray without GI...

do your shadows in scanline

comp them all together in combustion.

 

ps...render out relections in a seperate pass

This should help you figure out what settings to focus on. It assigns an alpha numeric value to each setting, and therefore, tells you which settings are critical, important, unimportant, etc. Hope it helps

out of curiousity.... what kind of rendertimes are you getting for each frame? Are we talking 1 hour ?

[Joseph Petrino]

Are you pre calculating your irradiance map?

 

If not, that will cut render times a lot.

[shikodesign2000]

In fact I use the tutorial in spot3d.com: "walkthrough animation tutorial", i don't use scanline renderer at all.

How can i render the shadows alone?

Yes, I precalculate the LC and IRR maps.

The average render time for each frame is about 8 minutes.

The average render time for each frame is about 8 minutes.

 

8 minutes...I'd say what more could you want??? If I can keep mine down to an hour or so I'm happy.

[BrianKitts]

I agree... my last interior animation was pushing 25 minute render times (and that was after optimizing). At 8 minutes a frame your downfall probably isn't your settings/render engine, its your available resources/renderfarm that's holding you back.

 

At which point I would look out to companies like respower, it's amazing what you can crank out through them in one day with a $300USD- 24 hour subscription.

 

I don't have the resources to do animations for my freelance work so I just test locally and farm it out. I put that rendering fee right into the contract as a line item that gets billed right along with my services. then if they want to make changes down the road.... yup $300 fee + my services again.

Ok, that's good, but maybe my project is not so huge and so complicated, I wanted it to be somehow simple, cause this's my first vray animation project, so I didn't focuse very much on high quality interiors details as the way of making the process itself:rolleyes: , (though it's a work for a client), I did animation before, but not with vray.

 

Anyhow, I just meant that if there's a critical settings that I can minimize it without affecting quality too much and can speed render time, I just want to know them.

 

By the way, tomorrow, I'll upgrade my pc from P4 3 gegaHz, 2Gega Ram to 2core2due, 4 gega ram, I hope this will help me in speeding things:D

I dont mean to discourage you from learning about the critical settings, but knowing some good settings is going only help so much. You really need to know what the settings do, because every scene is different and what works for one might not work for another. Definitely figure out what the critical settings are, but dont just memorize some good values, memorize what they do and why.

8 min. is not a long time- so simple scene no detailing ..... what ever. I think people will agree with me, 15-20 min render (GI) time is very comfortable for an animator ( archi. viz industry).

[shikodesign2000]

Brian, I don't know why you understood that I'm afraid from learning all necessary crtitical points in vray rendering!! ofcourse not, I want this very much, and as you said, I beleive this is the only way to make a great control on your project and all scenes in both stills and animations.

 

By the way, your tutorials (critical points in vray) & (image sampler) are so good, and I get a great benefit from them, really, I hope to see more in these areas, e.g. if you can cover more rendering areas, this will be wonderfull.
