My composure output is a render target2D,and then create a material by it. I give this material to a plane, and it works well in editor, but failed after packaging. Am I wrong in package setting? Or maybe composure can only run in editor, not in packaging game? Appreciate any help.

I am sorry to tell you that I didnā€™t work out this problem. However, I copied the code of ā€œChroma Key Materialā€ which is in composure detail panel, and then pasted them in my custom material. It worked in package game, but I donā€™t think it is the best way to resolve this problem. So sadā€¦ ---

Hi, I have a simple Media Player and is receiving video feed from camera via HDMI, On Begin Play in the Level Blueprint I open the Media Player and play. If I create a plane and apply the material it works. The problem is that when I click play composure is not working in play mode but in the Preview com I can see that itā€™s workingā€¦ Could you help me? Iā€™m new to this and I need to go in play mode to get the data from vive tracker. Hereā€™s a quick video: [- YouTube](https://www.youtube.com/watch?v=pUFXUs9juKE) ---

Have you choose the correct output in the composure? Like render a 2D asset, add to viewport ---

Hi All, This problem actually kept my head going for a few days but eventually found a workaround. In my case this error kept appearing: Error: Couldnā€™t find file for package /Composure/Materials/Output/M\_TextureCopy requested by async loading code. NameToLoad: it seems that originally the M\_TextureCopy is not used and therefore not getting cooked but in reality this texture is very much needed. So to make sure it gets cooked i applied this texture on a cube somewhere in the scene and now my render target is not black anymore i hope it helps ! ---

Thank you @basknappers! To build off of your solution, you can add the directory `/Composure/Materials` to Project Settings \> Project \> Packaging \> Additional Asset Directories to Cook. This way, you donā€™t have to have a silly cube laying around. ![image](https://d3kjluh73b9h9o.cloudfront.net/original/4X/d/a/a/daa86c42221eb888c4b99e9b4c2c273abc560103.png) Assuming this is a bug, so I did file a bug report. Kinda new to this though, so Iā€™m not sure where it went after I submitted šŸ˜
