CGA - support for ProxyMesh

[CopyPasteBugs]

I tried to export one animated mesh as CGA with mesh for collider, but without any success.
Is it supported proxy for CGA for now?

Also I found what only one mesh can be exported per file.
It means for example: to make animated sci-fi doors with three parts, you have to create three *.cga file with three *.anm file (

I guess this is not limitation of CGA file because in Maya they may have complex meshes with using separate colliders for parts (see last pics) https://www.cryengine.com/community/viewtopic.php?f=315&t=133020

Hii @CopyPasteBugs,

ProxyMesh is supported with CGA. Just have to be sure your proxy mesh use same animation with render mesh. If you attach/join your proxy mesh to render mesh, that is going to be accomplished. I advice to use joined mesh. But If you want to use separate mesh for proxy, you can accomplish this with constraints, but in that case don't forget bake it before exporting. As well, you have to be sure material name convention set correctly. Even after all of those, If you still get a error, you can share screen shot with me, I will consider to fix in next release.

Secondly, BCRY supports multiple CGA and ANM asset exporting in a project, just you need take care of a few things. Again you can consider to share blend file with or screenshot when you get error message.

Thank you.

Hi @feedbackex thanks for reply.
I tried in many different methods: various method of parenting of objects to each other and name conversation, but it still not working for me(
so, I think the better way to figure out with this Issue it's just share my *.blend file, it's would be awesome if you check it for issues or share your example file with complex mesh animation in one CGA.

There is my files for test door with three parts and one animation: https://github.com/CopyPasteBugs/VFiles/tree/master/CGA%20complex%20model%20tests

I'm use GeomEntitly from CE5.3.1 to check cga model and animation. click/unclick on physicalize option to show up model in viewport (ofc if it exported properly)

Hi @CopyPasteBugs , I have checked your blend file. Problem is that; each CGA node have to be one root mesh for CryEngine elsewhere you get warning and your CGA object doesn't work properly. You can fix that with make child left and right door of main part of door in Blender, then you can reexport it.

You have to be also download and install latest BCRY, which I have added parent/child #106 relations yet.

Lastly about CGA physic proxies, everything is working well in background for proxies exporting. Unfortunately, CryEngine discards physical proxies, I don't know why, also I tried it with Maya, result is same CGA object physics aren't shown. I think it's problem about CryEngine, or maybe they don't want to use physic with CGA objects, I couldn't find any document for that. I think, you can use separate physical object until CryEngine fix that. You can hide separate physical object whenever door is open via Flowgraphs.

Hi @feedbackex, thanks for fix it's awesome, all working properly with animation now.

about physics:
I guess they doing in-house test with GeomEntity only for character and models(Static/Rigid), so they do not assign any slot (when doing physicalization) in their GeomEntity for models.
I fix a little GeomEntity (https://github.com/CopyPasteBugs/VFiles/tree/master/MyCGAGeometry)
with adding slot 0 and got this:

first entity is fixed slot for model
and secod is default GeomEntity

Also I update my door.blend file with adding proxy for main mesh, you may put this file into repo as example with CGA (outline hierarchy).

That is great @CopyPasteBugs,
Maybe you can consider to pull request your geom entity to CryEngine.
Also thank you for blend files, you may pull request it, under Objects/GeometryAnimation/Door.blend.
