  4. Hi to all, i was preparing my source for a pyro simulation and i incurred in a weird artifact As you can see in the images i uploaded in the edge of the geo there is this weird blur, the problem is that even if i turn up the density or the division size i get this, it occours also in the pyro sims making everything look srange It couldn't be neither my video card drivers or houdini, i already tried reinstalling it without obtaining anything Any advice?

  6. Hi guys, i was doing a test render and when i looked at the alpha and at the Zdepth pass i was wondering why the edges were so sharp and "artifact looking". Here's the result whit and without the subpixel sampling enabled in Mantra with PBR and 3/3 sampling. In the firs attachment there is the one without the subpixel checkbox enabled, in the second there is the subpixel enabled and strangely the alpha is hasa got some artifacts , why should it happen ieven if it slow down a lot the render time and get as result ultra large images? Thanks in advance Alpha_NO_Subpixel.tiff Alpha_Subpixel.tiff
