The
following is a list of known limitations for this version of the 3ds Max FBX Plug-in:
3ds Max FBX Plug-in does
not support environmental texture maps (Environ option).
Memory
issues can occur when you use scenes with an excessively large polygon
count. If you have these problems, keep the scene minimal by avoiding
an excessive polygon count.
The
3ds Max FBX Plug-in does not retain amount values for Standard materials,
such as Bump, Diffuse, and Specular level when exporting. The FBX
format saves none of these values and sets all channels to a value
of 100 on export. The 3ds Max FBX Plug-in reads the glossiness and specularity
amounts from shader basic parameters and not from the Maps rollout
in the Material editor.
The
plugin does not export Morph information with Patch geometry.
The
plug-in does not export 3ds Max Lock information from Ambient and Diffuse
channels. If you define a texture in the Ambient channel when you
import an FBX file into 3ds Max, the Ambient, and Diffuse channels become
unlocked. To preserve the channels’ locked state you must lock them
after you import the scene.
The
plug-in converts Target Direct lights to Spotlights.
In
non-Revit to 3ds Max workflows: The plug-in does not support Skylights
(and their targets). Instead the plug-in converts them to null objects.
The plug in also converts mr Lights to Standard lights (for example,
an mr Area Omni light becomes a Standard Omni light) and Photometric
lights become Standard lights (where they lose any Photometric-specific
values).
A limitation
exists where objects exported with the FBX format remain in the
last state shown in the Viewport. The plug-in exports any vertex
animation on an object in its current PRS coordinates. For example,
if you export a cylinder with a 100-frame animated Bend modifier
at frame 50, the scene shows the cylinder at a 50-percent bend.
To accommodate this limitation, position your Time slider at the
point in the animation you want to export. To retain the entire
animation, create a selection set for animated objects. Then, activate
the Include > Animation > Point Cache File(s) option in the
3ds Max FBX Exporter window.
When
you enable Shapes and NURBS curves in the Viewport, the Shapes export
as editable meshes, and the NURBS curves export as NURBS surfaces.
For example, if you had a circle shape enabled in the Viewport,
the circle would become capped on export.
For
improved interoperability, keyframe animation set on controllers
with TCB interpolation or tangent slopes set to Fast, Slow, or User
resamples systematically.
