DAE file don't load

vvvv beta question
#1

Hi, I’m trying to open some .dae models I build with Blender.
The DirectX 11 assimp loader seems not works. I have always to load files passing thru DirectX 9 mesh.

In addition to I get a big vertex count, almost 6 time bigger (3396 vertices) than the Blender vertex count.

I attach the Blender and dae model and a patch to open it.

daeModel.zip (161.7 kB)

#2

seems to work for me with Assimp ScenFile -> Mesh

About vertex count i have no idea, maybe retriangulation in export settings in Blender?

#3

in 3DSmax i get:

"While reading or writing a file the following notifications have been raised.

Maybe you need to collapse all modifiers to “editable poly” or mesh like in 3dsmax before exporting to prevent retriangulation?

In 3dsmax the vert count is the same as you have in blender so maybe its just the tris multiplied by 3 xyz

#4

Those extra vertices should be extra vertex attributes e.g. split normals, tangents, bitangents, vertex colors or other.

#5

did you unwrapped UVs? because assimp wont work without UVs

#6

Mmmmh, I’m happy to discover the SceneFile node!

For the camera and lamp, I don’t care, I don’t know if it creates computational problems, like some extra cycles but I can erase them from my files. I usually keep them to easy test the objects in Blender.

The modifiers are already been applyed, there’s no modifiers or something strange going on in my files, all plain triangulated geometries.

For the 3DSmax notifications, yes, blender DAE is a bit strange… when I used it for an AR project I had to modify all the lights by hand…

Could be nice to understand the problems with the Assimp loader, maybe some DX11 devvvv got the answer.

Thank you.
