I created a GDTF File and opened in GMA3 and Vision. In GMA3 is the fixture good but in Vision it Looks really strange.

Is it a Error from my GDTF File or is it a Error from Vision?

I would venture to say that it's with the way in which the 3rd party software[Vision] reads the format.  MA International is one of the leaders in this format development and I would lean towards what they are rendering as a way to validate the GDTF file you're using.  If it visualizes in the web builder, if it visualizes in MA3, but doesn't visualize correctly in Vision....?  H'mmmm...wonder who is odd man out?

 

Good luck!

I have found some of your files @lyon470 and can see the issue with them.

Models must be drawn with local coordinates at 0,0,0 and the offset (related to its parent geometry) is then given by geometry offset attribute. Typically, this is Z, negative.

Your base and head are correct, but Yoke has to be modeled/moved about see image below, when offsets have been put to 0.

Also, these models are huge. GDTF spec says:

All models from a device combined should have a maximum vertices count of 900 to 1200.

Your models in total have 13000 in some cases.

Cheers

Thanks a lot.

I have reduced the Vertexes with MeshLab and now everything is correct in GMA3 and in Vision.

Is the Maximum Number of Vertex written in the Wiki ?
