Memory Leak of materials in Unity

hannibald

I have a momery leak in my project. I tracked the position of memory leak. It happens in SkeletonRenderer::LateUpdate.When call meshRenderer.sharedMaterials = rendererBuffers.GetUpdatedSharedMaterialsArray(), Old Materials is unused and never GC by Unity except call UnloadUnusedAssets.
Please Check the problem.My version is Spine 3.8

We are sorry for the inconvenience. Does this also occur in the built executable, or only in the Editor? In general only used materials should ever be referenced, GetUpdatedSharedMaterialsArray() only assigns existing atlas materials at an array. Could you please provide us with a minimal Unity reproduction project that still demonstrates the problem? You can send it as a zip package to contact@esotericsoftware.com.

Thank you for your reply.
Yes, the materials is existing. But after meshRenderer.sharedMaterials = rendererBuffers.GetUpdatedSharedMaterialsArray(), the materials number is increased and native memory also increased in android studio. when i call UnloadUnusedAssets(), it came back to normal.
I will prepare a simple example and mail to you ASAP.

Thanks for your investigations, looking forward to the reproduction package.
