Lightcache problem

[jonnybefree]

Hi to all,
we are working on a very big project at the moment, and using
irr. map / light cache for rendering.
so my question is: does it matter in wich size i calculate the LC, when the final rendering is 2600 x 1300?
can i calculate the LC in 300x200 in this case?

best greetings and thanks

No, it doesn't matter. You can calculate the light cache at whatever resolution you want.

can i calculate the LC in 300x200 in this case?

Yes, you can do that.

Sorry for asking, but to make it clear for me. When I use LC for rendering, and I'm producing Hi-Res images, I can precalculate LC with small resolution, e.g. 300x200, then save it and re-use it for rendering in higher resolution with no lose of quality?

It appears Vlado means that LC is resolution independent. That is, it does not take into account the output resolution of your image.

So, the rendering time and quality will not change if you change your output resolution.

Vlado, am I correct?


Thanks,

You are correct, gio. Some examples of this can be seen on this page:

http://www.spot3d.com/vray/help/VRay...lightcache.htm

It gives an example of the same scene rendered at different scales and at different resolutions and the resulting light cache. As you can see, the light cache is the same regardless of image resolution.

Thanx Vlado, now it's absolutely clear

Strange....it seems that when I increase the resolution the LC time also increases!?!?
