Hi @Jobbizz,
it’s a quite usefull feature to render and display a performance-friendly cube-map of the nebula when arriving at a certain point in space and the background is just appearing still. This way you may also spawn another nebula (like a sun) without performance or overlapping issues. So far we did not have the time to implement this feature for V2 but in the further progress of our project it will be and so for the future plugin release.
Let’s say you do this by yourself in Blueprint: Take a look at the UpdateNebulaRendering function and you may see how to draw the current nebula-material into a rendertarget-buffer in respect of the camera-transform. Copy and modify this function to draw 6 images in each direction and set those as texture-parameters in a background material of a hollow cube in the level. You may draw just one image per frame over 6 frames to reduce the lag! also remember to set the ViewAngle and AspectRatio parameters.
Have fun and let us know if you get along with this approach
