ok update, the smoke collision works like a charm now, even though your images wasn’t working It was obvious what was to be moved. The flashbang still doesn’t do the white flash effect, I removed files from vault cache and redownloaded made new project, closed it then added your asset to the project, but there was no change still no flash effect, the image is there but no white screen effect. Anyways I’m happy I got the smoke I was after too bad the collision requires it to be cpu particles but that’s ok good ole fire and smoke just got to be on the cpu if you want lighting and/or collision -_-
