Artifacts in Volume

Recommended Posts

Hi Guys,

 

i have a weird problem. When i render a cloud with depth map shadows everything looks great in render view.But when i render about mantra node to hard disk there a some artifacts. fThe Light setup is a sun light and a shadow map  of 4k. I changed every settings in the shadow tab, like bias,blur,quality... But nothing happen.When i change the light position, the artifacts appear on a other place. So i think there is something wrong with the light.

 

Has anyone an idea what the problem is??

 

Here a both pictures:

If I recall correctly, the render view tab is only using raytrace shadows, whatever the settings you put on your light.

 

Render in mplay to double check you still have this problem, or switch to raytrace shadows and render through your mantraROP, you should have the same result.

i've found renderview doesn't always do the correct pre-processing.  for example, if you have a geometry light that uses point-clouds, it won't recompute the point cloud if you change settings.  could be something similar with generating depth maps.  try stopping and restarting the render to force a refresh.
