5 cloud layers
Micro detail 0.8 AA6
Rendertime about 2 hours

Are you using v3 or v2 clouds? I notice when v3 clouds start getting too hazy and mixing, render time spikes, in once instance almost 100 fold. Light calculation that took a minute took over an hour.

Clouds are v3. I do not get it either (varying settings and render times) These all have low density and no voxel setting changes

I have another image that without clouds, 10 objects and 5 populations and renders in 25 minutes without clouds. When I added ONE cloud layer back in, 11 hour render!!! but micro poly detail 0.8 and AA6 on both.

I don't really know why this is happening, but I'd like to understand it better. The next time this happens, try reducing the number of voxels to only 1 million, and see if this helps.

If you have a project you can send to us, please do. We might be able to figure out where the problem is (either in the scene setup or in Terragen itself).

Just because milk is white doesn't mean that clouds are made of milk.

Thanks Matt! I will check the voxels, sometimes I do set them at 95.... :)

 :o  That might do it. I'll disregard what you said earlier "These all have low density and no voxel setting changes" ;)

It's less likely to be an an issue if you have tons of RAM, but I'll know more if I can test an actual project.

Oh sorry, I wasn't clear. The clouds with lights are all rendering great!Really fast.
This image (last of the series) was the high voxel count I have lowered it to re render. It took six hours just to get to the tree tops....

Oh, I misunderstood, sorry about that!

Which image in this thread? Which Reply # ?

Sorry, I didn't see this last reply. It is on page 3 of that link.
I am trying to direct you here with picture link...mushroom tree
