Opacity Maps / Cloudscape Creator

Jason Galterio

I thought I saw a thread on fixing the Opacity maps in Iray so they no longer outline.

Does anyone have any pointers to fix things like this from showing?

Not sure if the square cloud outlines are specific to Cloudscape Creator or a general change to the way Opacity maps are handled. I thought the latter issue had been resolved.

I thought so, too. Decals do the same thing if the opacity map masking is not 100% black [0, 0, 0]

I did a little more investigating.

The edges on the clouds don't show if I use the bare sky HDRs that come with Cloudscape.

The edges do show if I use the Skies of Economy HDRs.

I know that wasn't an issue before, as I used them in conjuction all the time.

The solution I am going with right now is using the volumetric clouds from the Cloudscape product. I hadn't really experimented with them because I expected them to take longer to render. They are actually much quicker.
