Blender will be dropping support for COLLADA soon, citing lack of OpenCollada maintenance as a compatibility and security concern. Several tools only export to COLLADA, and the Models Resource community currently only accepts models in .obj or COLLADA format.
I want to save this format. I think it should be updated, not abandoned. Please, if anyone at Cronos Group has any interest in updating and maintaining OpenCollada again, I’ll learn C++ and update it myself if I have to. If the problem is that the format is outdated or obsolete, update the specifications to 1.6. It could support more effect profiles and shader languages, like slang or OSL. It could make multiple UVs easier to work with. It could have all the features and functionality of glTF.
Hi!, I am working about COLLADA in Khronos Group.
Thank you for your question.
There is no discussion about COLLADA 1.6. Most recent modification of COLLADA is ISO 17506 Amd-1. It may be COLLADA 1.5.1. However it is not the new version, but it is correction of error in 1.5.
My question is;
A. What features do you want in 1.6 ?
B. If we have good(or perfect) translating tool from Collada to glTF, Should we develop COLLADA 1.6 with all features and functionality of glTF?
How about support for more curves, surfaces, and effect profiles? I’m no geometry scientist, so i don’t know what new paths and curve could be or were to learn more about them. Instead i’m pulling from whatever Blender supports. Apologies if some ideas may already be supported under different names. For curves, there are bezier, nurbs circle, and path. Nerbs curve and nurbs circle are also under “surfaces” in Blender, not just curves. I don’t know what the difference is. Collada already has surfaces for cylinder, sphere, and torus, but blender has nurbs cylinder, nurbs sphere, and nurbs torus. I don’t know if there’s a difference there, or even what a nurbs is. Finally, Collada has support for shading languages like glsl, gles, and gles2, so how about a few more? Vulken, hlsl, and osl. Apologies if I misunderstand something about them like if they aren’t actually even the same category of thing or something like that. Metaballs.
