Mesh memory leak in NGUI 3.7.4

[ded_pasha]

Hi!

I have Mesh memory leak in my project(profiler show - don't saved in NGUI), it happens when I add new windgets to scene. And drawcalls don't trim mesh.
I have read this post http://www.tasharen.com/forum/index.php?topic=6210.0, but I have this code in NGUI 3.7.4 and it doesn't help.
    
Any help is appreciated

3.6.4 is quite out of date, but that post you linked is even older, and the code mentioned within is already a part of NGUI. Mesh not being trimmed? If you mean mesh buffers being bigger than needed, that's an optimization done to reduce GC allocation.

Hi!

Sorry, I'm mistake about version of NGUI, my problem on 3.7.4. When it's not trim(load new GUI: windgets...), Mesh take huge memory. After load/unload widgets, mesh doesn't unload memory.

So, my test show when forced trim memory is ok, if not forced trim mesh take more, and more memory.

Meshes are tied to draw calls, not widgets -- and they are reused. If you want to clear everything, you can call UIDrawCall.ReleaseInactive() function after disabling/destroying the UI. Note that all destroy calls are delayed in Unity, so you need to wait a frame.
