::A Quick look at the Lightmap set-up::

[gilicom]

alt + enter work just fine
thanks

[natty]

Sorry daforce i'll have to disagree with you on that .. Lightmap is camera dependent, so can be used for all .. e.g Exterior .. walkthroughs.. well everything.

i normal do my test render's with lightmap on the first bounce and when im happy swap it to the second bounce and use IRR for the first..
where i find lightmap good its not good enough for production first bounce. pretty much like photons.. so i use IRR to refine the GI.

[DaForce]

ahhh ok.

I thought it was treated similar to photons. Thanks for the heads up

s0real:
Did you get the TSCC codec that i posted the link for?

[gilicom]

I've tried the same settings on the Cornel scene
How can i make the walls smoother , also the shadow details are pixeled if you know what i mean.

[s0real]

yep. i got the codec and installed it.
i probably just need to restart or something...
i'll have to try it in a bit. lots of renders to get out + holidays tomorrow!

[natty]

Looks to me gilicom you havent got enough light in there ?
also dont worry about shadows until you go to the IRR stage..

[DaForce]

s0real:
Hmmm you shouldnt need too, ahh well see how you go later after a restart.

[gilicom]

Hi Natty i'm not talking about the lightning of the scene
but if you look at the left wall its not smooth like when i render it with irr map.
i'm asking what is the parameter that smooth the solution?

[natty]

are you direct computing your lights ??

[gilicom]

can i send you the scene?

[natty]

yeah sure ..

[natty]

Hi gilicom
basically your lights need to have smooth surface shadows on and the shadows ar being directly computed, so they will look a little grainy with low subdivisions, yours is 10 .. try 15-20.

i have a question about irradiance maps
if i calculate my irradiance map for an image whhich is 640 x480 pixels and save it
can i use it to render a 1600x1200 or bigger image

[natty]

you can but it will look bad... only double it .. thats it.. by the way this topic is about Lightmap. !

[haneet22]
