Stefan Ihringer<p>End of the week accomplishment: compiled <a href="https://mograph.social/tags/ocio" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>ocio</span></a> and <a href="https://mograph.social/tags/oiio" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>oiio</span></a> myself from git. I like how well it works. OpenImageIO even pulls in necessary dependencies on its own.</p>
Stefan Ihringer<p>Does anybody use DWAA compressed exrs when rendering multi-part or multi-channel exrs? I converted some renders with AOVs using <a href="https://mograph.social/tags/Nuke" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Nuke</span></a> and <a href="https://mograph.social/tags/OIIO" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>OIIO</span></a> and they got larger rather than smaller! Also, the compression ratio doesn’t have any effect on the resulting file size and visual quality of the AOVs at all.</p><p>DWAA works with regular rgb channels though. Did I find a bug in basic <a href="https://mograph.social/tags/OpenEXR" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>OpenEXR</span></a> code?</p><p><a href="https://mograph.social/tags/vfx" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>vfx</span></a> <a href="https://mograph.social/tags/VFXPipeline" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>VFXPipeline</span></a></p>
