Are hierarchical models supported for any of the geometry importers in
Away3D? My (.obj) model is currently textured only on the top level
of the hierarchy, and I'm not sure if it's because of the way I've
exported or imported.
I've remarked this behavior when meshes/polygon group are using the
same textures in some applications. Some apps simply omit to add the
require mtl usetexture id tag.
the fixe is often to knip and paste the polygongroup/mesh or add the
tag by hand, it would then be seen as a new mesh. If the problem is
still there
send me the model + mtl offline please. Note that if you do get a
white texture instead of a default linefill, its because you have the
wrong filename in the mtl file.
Also, Away demos such as Green Planet display an impressive number of
polygons. Aside from the fog filter, can anyone offer any
optimisation tips for calculating larger numbers of triangles. Are
some model formats faster than others? I seem to be working with far
fewer triangles and already noticing a drop in frame-rate.
Its because most of the most work was about preparing the geometry,
animations, textures and testing and comparing speeds.
each and every textures, models, were made to work together. Peter and
me spended hours on skype comparing best fx/animations at best costs,
to find the best balance.
It mostly come down to one very important point: You have to define
per model the size of texture per face so that the flashplayer has the
mimimum of efforts to do on the rescale.
Your work as a designer is to ensure its still looking good. To reach
that level of detail you need to have a hudge map. but if you do so,
then you end up
with a large swf or you need load stuff forever like I see too often.
One solution is to load half size and blowup by code before applying.
but there is indeed a certain amount of feeling and a serious dosis of
trial and error in the game.

Does the fog filter speed things up? I thought it was more a visual
effect then something that made it easier on the 3d engine. I would
think cpu were wasted trying to calculate the effect.
I sure speed up things because it has a depthfilter in its hart. Note
that you can use a simple depth filter as well.
@Paullaster/Gabriel
Has any progress been done in tracking down the memory leak in away3d?
I was in London yesterday and Rob told me he was doing a lot in that
field. Another issue for the clearance of primitives was fixed last
week.
I haven't seen any problems when using this camera but I never use
those xml files... If the problem is still there after the upcoming
updates,
please send us some code/model to be able to reproduce.

It wouldn't make so much sense if the memory leak comes from the
HoverCamera3D (since it's pretty much a cos/sin calculation). Maybe
it's more related to clipping stuff/DrawTriangles that could vary
depending on camera settings and your model.

Yeah I think its with the HoverCamera3d. Very simple bare bone
application Away3d. Create scene adds collada model. I created the
scene as a test to see if it was something wrong with what I was
doing. I did plan to change the camera and do the same test. I
created games a few games with other cameras and didnt have that
problem.
It is a collada imported model. which was another theory of mine.
