Render never stops #158

Open bupla opened 8 years ago

bupla commented 8 years ago

Hi, when I want to render a scene, it never stops. In the terminal, the percentage of rendering is blocked at 0% even if the image is calculated. I don't have any error message. It's the same on my computer or in the render farm I use. I tried to reimport the objects in another file that worked but it still the same. I can sent the file. Thanks.

Sure, send it.

Thank you, I've sent you the file. Apparently, it cannot write the output image file.

Apparently, it cannot write the output image file.

Fixed with https://github.com/bdancer/vb30/commit/31bda49d9c3873734a7d2a2588e6b0435888795a

Thank you, I've sent you the file.

Progressive sampler has 3 "render time" controls:

and stops render whichever is achieved first. I haven't found yet any issues; may be for this scene 100 subdivs is just too much.

This is how it stops for me for 10 max subdivs:
