I infinitely prefer using the newer interface of the v2.6 series Blender, but to create the Kuju .IGS files I need, the only exporter I know of only works on v2.49. Until recently I found I could develop in 2.62 and then load into 2.49 for export and it worked ok - I got a complaint about losing animation data, but I’m not using animation.
I’m developing a model of a large building and had been using that route but recent changes caused 2.49 to hang indefinitely/crash on loading the .blend file. The changes were to UV map the structure using U&V-repeating tiles rather than singly mapped (& to do this I found I had to assign each set of faces using a given tile texture as a separate object).
Does anyone know why this might be happening, and importantly of a way around it?
[[I can export from 2.62 into 2.49 using a Wavefront .obj file - but then the scale is messed up, and the exporter then hangs when trying to “map blender to IGS structures”, which makes me think it’s not a good route!
I have also tried importing first into blender 2.55, saving again and then into 2.49, and also importing into 2.63 and saving using the “legacy mesh” option. Neither makes a difference to the result.]]
