Pixelation rendering bug

Post by ShawnCG » Tue Jan 14, 2014 7:43 pm

I am having issues where pixels with near-zero value do not render correctly. See the following annotated screenshot. The un-rendered pixels have values of about 6.0e-8 and lower.

Note that if I set PixelRender = false, the areas below the problematic threshold are rendered correctly (see the next screenshot).

Can you offer any advice on how to work around this or help with a fix? It is a big problem for us.

Thanks for reporting this. Bug indeed. :oops: The pixel image has 24-bit value resolution. If value went under 1 / 2^24 (approx. 6e-8), it was wrongly interpreted as out-of-the palette range value.

The fixed assemblies are here:
