hi-res rendering

i am trying to render out a hi-res (3600x3600) image and it is taking forever to go through the “prepass” processing. there are a handful of materials that use glossiness - am i right in assuming the glossiness is what the “prepass” calcs is for?

i have interpolation used for all the material with glossiness. any other ways to speed up this part of the rendering process?

also, when creating the irrad. map for this scene - does it matter what resolution the image is set to render to?

jsut trying to understand how everything works together - irrad. map, rendering size, rendering time.

The problem is due to the fact that interpolations have the original min and max settings, but you can increase those settings to speed the interpolation prepass like you do with irradiance map…

Gonçalo

which way do you mean by increase though?

for example, i have a wood floor with glossiness and the settings are:
min rate -3
max rate -2
clr thresh .4
mrn thresh .4
samples 20

i thought it makes things faster if i changed the min/max to something like -4,-3?

I thought that too…

does it matter to select “use interpolation” when the glossiness is set to 1.0? on a glass material for instance?

no, but lowering the subdivisions will…

No it doenst…

I’m batting a 1000 today…

I meant to say depth

Yes you right Eric :smile: , I didnt see your post before I post mine :sweat_smile:
