.dae multiple Triangles nodes in one Geometry node cannot be displayed

[jiaqzhao]

[ FlexSim 24.0.1 ]

If there are multiple <triangles> nodes under the same <geometry> node, the .dae file cannot be displayed in flexsim. I have put a snapshot as follows, this file is not supported in flexsim.

It is very strange that my file can be imported into the OpenRAVE software without any error. If it is not correct, it cannot be successfully loaded. Here is the file I saved from the OpenRAVE software, cncmachine(new).daeand this Collada file can be successfully loaded in FlexSim. I have compared the difference between the two files. The new file does not use "Normal" definition in <mesh> and it works in FlexSim. I think both definition ways are correct, but I still do not understand why my file is not supported..

Yes, this file loads nicely into both FlexSim and 3ds Max with minimal warnings.

Using a diff tool to compare the files shows many more differences than just the '"Normal" definition in <mesh>':

I don't know which of these many differences are critical to proper dae composition, but this file does seem to be correctly formatted, unlike the earlier attached files.
