Hello,
Just begining here, but I am pretty stuck with mantra refusing to render shadows when I launch a complete animation render.
The shadows (of one area light) are rendered in the render view though but not in the final anim.
Here is the scene, sorry if it turns out to be obvious, I have tried a ton of things in the mantra node.
Many thanx for your help.
Jérôme

I just looked at your file - is there a reason that you've set the shadow type on the light to depth map as opposed to raytraced?
Regardless, there were a few things - the light needs to be able to “see” the objects casting a shadow if you're going to use depth maps (I looked through the light and rotated it to see your objects), the bias and shadow blur were too high. See attached.

There's a cool trick to making the IPR viewport use Depth Map Shadows. You can add the ‘Preview’ tab to the MantraIPR Rop and control all those little details. Just uncheck ‘Always Use Raytraced Shadows in Preview Mode’
Even without that tab you can usually switch the micropoly or other rendering engines by simply unchecking ‘Preview’ in the IPR viewer.
Sometimes it's stubborn and one needs to press the red stop button first, then render button, to switch.
