@@Xycaleth Any ideas for what could be causing those weird normals? Also, I was in source engine's hammer map editor just now and I saw there is a cubemap size setting for the cubemap entity. Perhaps the mapper being able to set the cubemap size would be handy for rend2? Was thinking a field to input the size, like for example: key: cubemapsize value: 128 There can be info on sizes and when is best to use what sizes in the info window. This could be handy as not all areas need the same size cubemap and may save on performance.
