Hi Everyone!

I'm rendering out a Texture Atlas for a smoke texture I made with Houdini Indie (16.5.268)

Everything seems to be fine, except I get this Moire pattern with the Render.

Everything looks fine in Houdini, and I've tried messing with the settings, but I can't seem to get rid of this annoying pattern. Any thoughts to why this happening, and how I can clean it up?


Things I have tried…

-Changing the Output Gamma.
-Rendering out only with the Mosaic (No Pre-Mult).
-Rendering out only the base EXR image (No mosaic or Pre-Mult).
-Changing file formats (JPG, TGA).
-Resolution
-Changed the File Raster Depth to all 3 options (Natural Depth, Project Depth, Specific Depth).
-Changed Image Color Space to both options (Linear, sRGB)

*bump*

Hey everyone, still looking for some help with my problem.

I'm linking my project below if you are able to take time out of your schedule to help!

All you need to do is…

(1) In the Node Editor > img > Problem_Child > Render_this

Render out the image, and you will see vertical lines rendered out.

If you go into the Composite View with the “SmolePillar_Looping_SmokePillar__v001_F4_exr1”, you will not see the vertical lines.

Any ideas to why this happening and what I can do to fix this?

I'm having the same problem. I read somewhere it was a new bug introduced and try downloading a new build. I suppose that means downloading a daily build instead of a production build. If there is any info out there on this vertical lines problem, please post. Thanks!

This appears to have been a bug. The upcoming daily build will fix it.

Please be aware that since 16.5.314, the default PNG Premultiplication setting on ROP File Output is “unpremultiplied”. I recommend setting it to default (if you're using PNG) or simply make a new ROP File Output node. Please check the version log for more info.
