I’ve been trying to build a face as per TorQ’s great tutorial ( https://blenderartists.org/forum/viewtopic.php?t=21066&highlight=face+tutorial ), and a longstanding problem has resurfaced.
Whenever I load a background reference image (view>background image), my processor speed slows to the point that work is near impossible. I’ve noticed this problem previously while working with a uv image displayed in the uv/image editor.
I can appreciate that blender is doing an awful lot of processing while these images are onscreen, so my question is this:
Is there an optimal image format that might lift the burden on blender while using background images?
So far I’ve experimented with .jps at bare minimum resolution/dpi, as well as greyscale images, but nothing seems to lift this blender-slowing burden.
Any pointers appreciated.
