Ir map blur?

[jow]

Hi im just having a go at a walk-thru test and i understand that its good idea to use the gi blur to smooth the ir map,only problem is when i use it i get these results,black splodges!
gi blur set to 5


no gi blur






any ideas why this is happening?
cheers jow

Jow, my understanding of the blur GI value is that it works best on smaller details than large flat planes like you have

[jow]

i see!so best not to use it then.ill render it with out blur and see what happens..
thanks for reply.

One question,if i did have say an area within this walk-thru with high detail,and used the GI blur to smooth the detail,i would still have this problem in this low detail area?
How would i go about fixing that?

Hi Jow

try changing the sample lookup method ... you need to have more samples with Desnsity based to get smooth results.. also try ticking Check sample visibilty.

you would be best not to use the blur GI and use a higher IRmap setting

cheers.
