GPU rendering of course (I know you probably won't do it).

Thanks romullus. I think I understand what is going on here now. I've thought I was using displacement on the jar scene as well but I was wrong. That's what was keeping me confused.

I really can't understand what is wrong with the normal map I've made. Here's the original png I'm using.

I tried, but the effect is far from it needs to be.

I've used displacement without issues before.

I'm experiencing some problems with normal maps and displacement where the edges appear jagged. Does anyone know what might be causing this?

Great work!

How did you create the normal maps?

I'm trying Corona.

Here's a render I've been working on recently. Any critique and/or tips will be highly appreciated.

And this is the reference photograph:

Not quite. However, I was removing the portals one at a time and if the noise increased, I brought that particular portal back in.

This is the portal setup that had the best results for me. There were three additional portals covering the top, bottom and front of the cantilever terrace. Removing each of those helped bringing down the noise a little bit. I haven't tried putting a portal in the window of the terrace though.

Here are the noise results for 20 (or 10?) passes:

all portals                           15.3
no portal terrace front            15.1
no portal terrace front, bottom         14.6
no portal terrace front, bottom, top      14.5

P.S. I also made holes in one of the portals, as you can see in the second screenshot.

After some tests it turned out that portal were useful in the small windows, the roof windows and the opening. Putting portals around the terrace had the opposite effect - they added more noise.

Thanks, maru.

I'll try to place a portal over the roof opening, and make some holes in it for the spiral stair. As for the front terrace I'll try covering all the openings.

I'll then compare how it goes with and without portals.

Hi all,

I have a problem placing portals. I was considering placing the portals in front of the windows in the courtyard and front terrace. But after reading some posts it seems that a better solution would be to place them somewhere on the roof and around the front terrace.

However now it seems that such placement will interfere with the spiral staircase and the railings.

Could someone advise what would be a better solution in this situation?
