<div dir="ltr">Greetings from <a href="http://www.renderstorm.com">www.renderstorm.com</a> !<br><br>This is *not* directly related to the viewport, but more related (*we think*) to the new requirement in 2.77a for hardware-accelerated OGL and any potential effect on spawning network rendering jobs in Windows.<br><br>Our render farm queue manager executes blender.exe -b at the command line using Windows "createProcess()" function.<br><br><b>Here's what we're passing to the rendernodes :</b><br><br>CreateProcessAsUser( token, NULL, commandToExecute, lpSA, NULL, inheritHandles, CREATE_NEW_CONSOLE, NULL, NULL, &si, pi)<br><br><b>commandToExecute typically looks something like this:</b> <div><br></div><div>["C:\Program Files\Blender Foundation\Blender\blender.exe" -b "\\DISKSTATION1\farm\SquidNetRenderFolder\sync\521450\87E82C8694\project\BMW1M Mike Pangpu.blend" -x 1 -s 4 -e 4 -j 1 -F EXR --python-text renderstorm_blender_0107.py -E CYCLES -P "C:\Program Files (x86)\SquidNetSoftware\SquidNet\plugins\\blender\squidnet_blender_gpu_render.py" -o \\Diskstation1\FusionIO_DS1\ProjectData\jobs\521450\6974A4\1AE094A25B\slices\slice-4\broken_277_agtest -a -y]<br><br><br clear="all"><div><b>This works great for 2.76b and previous builds.
