Vray Speed vs Quality

[SunGlare]

Hello,

 

I looking to bring down render time of this image.

Please give some ideas how to do this.

 

I also suspect that there might be some tricky switch somewhere, beceause scene is rather simple (except xref 230mb tree)

IrMap: low

LC: 400, 4pases

 

ImageSampler: DMC min:1 max:2

AA: Mitchell-Netraval

 

and it turn out to be 4.5 hours! on quad intel q8200, 8gb, asus.

at first it was crashing after it reached 5.6gb, but then I found this dynamic memory 400MB limit, and set it to 7GB.

 

also some spots showed upupper left area?,

also it is bit too dark, so I think I need to convert to gamma workflow(nightmare)

one direct light, enviroment ovrd 2.0, vray sphre wth light mtl inside(as a sky)

To summ up:

1. What do you thik about render time of it?

2. Where the color pixels coming from?

3. Is there easy way to convert scene form non managed to gamma2.2?

4. How do you like it, what you see?

 

 

Help me. Boys and Girls.

sounds weird

use a phys cam / sun sky and try reinhard color mapping.

Hey sunglare, I have some suggestions try switching off the displacement map for the wall. Secondly... I see your glass roof has glossy reflection try increasing the value say .85. By doing this u will at least know which one is causing problem right? Lastly since there's not much visible detail beyond the roof get it rendered in separate layer and comp it with blur filter.

One more step(sorry about that) usually objects like trees with opacity maps or heavy meshes take lot of time to render, so try disabling shadows for the tree!!

 

 

HOpe these makes sense.

So... to sum up...

...any thoughts on the subject?

We can "Sum up " only if u let us know whether u solved your problem mate!! Did you try those adjustments?

Thanks,

jkrock3d: I was impatient and posted it before your posts.

I need wall dispace, need glass blur on that level decreasing it will cause floor look too transparent, there is nothing beyond roof, so no need for layer-render.

 

I will take a closer look at shadows as I have pretty small shadow threshold, in order to show some tiny brickwork on the outside.

 

I'll try to turn of shadows for that tree, and adding some shadow mask, to see if will help.

 

 

Where those weird pixels coming from? huh... sun gamma radiation outburst?

but I dont use sun, as my skin is rather pale.

 

 

Thanks

Sunglare u got me wrong, Am just saying disable the settings so as to find out which one is eating up more time to render! Try to understand what we want to achieve here go step by step u say there's nothing beyond the roof, i guess u got me wrong there too.. i meant the glass ceiling where ur other (upper)floor is. We can see through some furnitures right? what are those?

U said it you are impatient my friend!!
