when I imported a new model created with blender into an older patch that worked fine with another 3d-model, I just saw a part of the model displayed. I could reproduce this behaviour via the helpfile of jit.gl.model and the Seymour character as well... In the patch below you see first working complete multiplication via jit.gl.model to jit.gl.multiple, and second missing multiplication (only the blue suit gets multiplicated) via jit.gl.mesh (note that the jit.gl.mesh itself shows the complete model @pos 0 0 0)

is there something that I am missing here, is there an attribute to display the full body of Seymour via multiple/mesh? or what do I need to follow when I export my 3dmodel in the 3d-modelling software(I tried for hours with different settings both to create obj and dae files or do get some information...)

this is because seymour has multiple drawgroups. gl.model outputs a matrix for each drawgroup, and in your patch the only drawgroup displayed is the first (or last, not sure). you could do something like create a mesh/multiple pair for each drawgroup, and each frame you send each drawgroup matrix to the corresponding mesh/multiple. you can hook a print up to gl.model, and bang the render context a single time to see what's getting output with matrixoutput.

alternatively, you can re-export your model ensuring there's only a single drawgroup created. in maya, this is done by selecting all distinct meshes, and choosing combine mesh (or something like that). you must also ensure that mesh has only a single material node attached to it. even if the mesh is combined to a single mesh, if it has multiple materials it will create a drawgroup for each material.

thanks, this answer is very helpful! didn't know about the single material node before...

model to multiple via mesh (matrixoutput) limited to one drawgroup?
