FR Interior

[Marq]

Hi,

 

This is my first FR interior, i still have to add some objects and materials but im concentrating on learning about the lighting now. Anyway, the scene is lit by an HDRI background and a direct light, there is no glass, all the windows are openings, had the same problem i've seen in a previous post, the glass kept most of the light from coming in no matter how transparent the glass material was.

 

 

This one has both the hdri background and the direct light generating GI, took 1:30 hs.

And here only the background generates GI, took 1 hour.

Settings..

RH rays 500

min/max 5/50

the floor material send multiplier is increased.

 

Any critics welcome

Thanks

are these normal render times for using final render?

What do you do when you animate?

[Christopher Nichols]

You can't animate it because it will flicker... if lights and objects are not moving in your scene, you can "bake" the light into the scene... the your render times go way down.

 

On the other hand, if your gi engine is fast and good enough, you can get an artifact free render and you can animated it without having to back it. Hence, you can have moving objects.

 

1 hour seems really high, even for final render. I suspect that it is because it is his first interiors.

To make indirect light (FR considers light from a HDRI as indirect) you need to exclude it from the MSP acceleration. This is easily done by expanding the MSP parameters rollout from the FR parameters menu, hitting the exclude button and a screen that looks just like the exlude/lighting menu will popup, then just select the glass and move it to the exclude side and leave everything else alone.

Hi, thanks for replies.

 

About the render times.. i'm sure it is because its my first interior so any tips are welcome, also i'm on a PIII 750 512 Ram so maybe its that as well, but if it's too slow even for this machine, i guess it could be because i didn't use local settings, i dont know what else could be because the scene is really simple... how can you reduce render times other than adjusting parameters on local basis?.

 

Brian thanks for the tip , i'll try that. One question, what is your criteria for using that in general?, in what situations do you need to exclude things from MSP?

 

Again, critics on anything are welcome

 

Thanks.

Leonardo.

Hi,

 

here is an update with the glass excluded from MSP acceleration, now i can have reflections and transparency without losing the lighting intensity from the HDRI background.

HI LEO.

I think 500HR is too much

and the MIN and MAX are too low

 

Try with:

HR-300

min 10-20

max 100-200

1/1

35% quality

min 5 bounces

refl 2

 

Good luck!
