I successfully opened and built the project attached to Case 1108597 in Unity 2019.2.0b1 a few weeks ago.
Today I re-opened this project in 2019.2.0b7 and triggered a build. Unity now displays the following progress-bar and the build seems to take forever, which I believe wasn’t the case in 2019.2.0b1 for example.
Unity seems to check every single prefab, for every shader, for every variation, for every rendering type. This seems to take a long time, is this the expected behavior?
Hi. I have a similar issue with Unity 2019.1.10f1. After updating to 2019.1.10f1, my project’s assetbundle build time is changed to x10, and always “Mesh Data Optimization - Resolving used channels” is shown even useCache=True and the project files is not changed.
I used ScriptableBuildPipeline 1.5.1 for building asset bundles.
Edit : Oh, please ignore this comment. It seems that there are some files which is not commited to my repository. After commiting all, building with same resources is completed in few minutes.
I re-tested it with Unity 2019.2.0f1, but the issue persists. I had to abort the build-process after waiting a few hours for “Mesh Data Optimization - Resolving used channels” completion which then leads to a crash .
Same issue
Happens only on build with a project created in 2018.3 and updated to Unity 2019.1.14f1
I see reference to Legacy Shaders/Diffuse - ShadowCaster
