Shading Domains on imported OBJ very slow... 2004-08-13 - By hdaggers2000
Back
Hullo.
I've imported an architectural mesh into C3. It is a single OBJ which seems to
have already had some shading domains defined since a single texture
appears differently on different areas of ther model (an archway shows the
texture rotated 90 degrees, while the wall shows the "normal" parametric
shader, while stairs show the shader enlarged 200%, etc). Within C3,
however, no shader domains have been defined, so I've converted the OBJ to
the Vertex Modeller and am trying to select groups of facets so I can name
them and apply different shaders to the various parts of the model. I think
this
is what I am supposed to do....
What happens tho, is each facet takes about 30 seconds to select(!) and
selecting groups of facets is impossible. I've never tried to define shader
domains on a Carrara-native model, but this seems rediculous. I'm on a dual-
processor 1Gig G4 (osX.3.5) and at this rate it would take days to select just
a
single area so I can name it! Am I doing something encredibly wrong? Is this
the normal behavior for Carrara? By closing all but one view and using the
"flat" renderer, the selection response time is more like 5-10 seconds, but
still!
My hope is that there is a tutorial for importing and re-defining domains on a
model (it seems pretty straight-forward in the manual, is it possible I'm doing
it
wrong?) Or perhaps someone could just confirm that "Yep, it's damn slow".
The facets don't seem to be unnecessarily large or complex.... Anyone have
experience with this "issue" -- if it even is an issue? Would a 3rd-party
program allow me to do this easier, better, faster?
Thanks again,
holly
