Heres on I've just found:
I have a skinned object using Slices and the prefix option.
When I try to render last from the mat editor I get the error
Skin AXP:
Prefix option for "Slice" requires at lest two objects
Continue
The scene renders fine from Keyframes or editor.
Erik, that oddity was explained by GYost as an oversight in the code, rather
than an actual *BUG*. If I have to do extensive tweaking of materials from MATS
EDITOR I hide any SKIN/SLICE objects so as to speed up the render/check
process. In cases where i have to actually tweak the SKIN material then I make
a simplified PROXY model and copy it a number of times. Then, in the MATS
EDITOR I will generate numbered variations of the SKIN material and put them
all to the scene, sequentially previously assigned… then go back to the 3D ED
module and render all the PROXY models. Crude workaround, but it gets the
tweaking session done with as little jumping between modules as possible.
