Debian GNU/Linux Jessie (testing)
AMD Phenom II X4 850
Broken: since added motion deformation blur
Worked: before and now with normal motion blur
Short description of error
Once particle system and explode modifier(!) got applied, render performance becomes unusable. See also .
Exact steps for others to reproduce the error
- enable motion blur with deformation
- remesh standard cube
- add particle system
- add blend texture
- and the most important: apply explode modifier (leave only Unborn enabled)
Test file attached:
The frame 1 where the particle system is not yet active is rendered promptly. Go to the frame 2 and the render process becomes extremely slow, though the region being rendered doesn't get changed by the particle system, because of the blend texture: only the almost left side emits particle at start.
