[GO] Objects sometimes turn bright white
Already posted this problem on the UE forums but maybe someone over here has an answer;
Sometimes, objects turn totally white
on the GO - see pic / movie. It only happens on the GO, not on Rift or
desktop.
In several projects, I notice objects sometimes turn white when loading
the streaming level a second time. Most of the time only the trees,
sometimes everything on the streaming level.
The trees are on the persistent level, streaming levels have a lighting scenario.
Anyone a clue what could trigger this and how to fix it?

- @imperativity I have spend some more time investigating this issue. In case someone else runs into this issue here's a workaround that seems to work (most of the time).In short: in the player blueprint, add an 'execute console command' with arguments: 'r.Streaming.PoolSize 3000'. Then it seems like the problem only rarely occurs on the GO.Longer version: My guess is: its a memory issue. It happens in all my projects where at the start, all the streaming levels are loaded and only one has its visibility set to true. If the projects gets bigger (textures, lightmaps etc), the problem
starts to occur. Makes also sense that the rift and desktop (using a gtx
1080-more memory compared to the GO) don't have the issue.In my app, using the trigger you can switch design options and for the most comfortable user experience, this only changes the visibility of a streaming level; the previous one is set to false, the new one is set to true.If you would load the new streaming level only at that point instead of toggling the visibility of a pre-loaded streaming level, this would result in a hickup for a few seconds which isn't really nice to look at. Also, this sometimes generates issues with materials with reflections (they are disabled somehow).Thanks for passing on this issue to your team.Max
