Missing/Glitching attachment at the first rendering on iOS

filterSekai

We have some of the characters that have rendering issue. Sometimes one of attachment is missing/glitching and occurred is not consistent (intermittent). We suspect issue caused by memory warning but not sure whether material will be purge automatically when device has leak memory. The missing material is randomly sometime body part, leg, hand and others. Could you give clue or insight why that issue happened ?

Here I attached the actual result that happened on our iOS Platform

it should be work fine like our expected result.

We implemented spine by using spine-cocos2d-objc and spine-c version 3.7 as spine runtimes.

I really appreciate you listening

Is there any way to reproduce this on our end? Could you maybe send a small sample project? Do you actually get a memory warning? If so, could you post it here? Also, could you try exporting smaller atlases and see if this changes the behaviour? Resource purging is up to cocos2d-objc and ultimately the OpenGL driver iOS.

The runtime is also very old, the same is true for cocos2d-objc which hasn't been updated since 2017 iirc.

Sure, I'll share resources and small program to your email. I'm not sure whether that was affected by memory warning. but I'm still findings out too. Wondering, could you give me example or reference about resource purging ?
Please put your email. Thank you

You can contact us at contact@esotericsoftware.com. Regarding resource purging I'm afraid I have no example or reference. Maybe the people of cocos2d-objc still answer questions on their issue tracker?

Hello Mario, I was sent sample project to your mail. is there any update ?

Mario

Can you tell me what email address you used to send the example? I searched our inbox but didn't find anything related to this thread.
