Hi,
I’m an university professor with a background as a 3D artist and creative coding and I was considering porting my phd project from Unity to Panda, in order to be easier to open-source the code (and also port my Python skills to C++) .
As a test-drive I used the GeoMipTerrain class to import and render the (very big) heightmap from my app to Panda, expecting Panda to kill it, which didn’t happen. Quite the opposite.
First thought was that I’m doing it wrong, which leads to the question about resources (documentation, tutorials) that can help me do the port specifically from Unity.
Thanks

BTW: below the render.analyze() dump. I know that a rescaling is being done, but the same is true with a 513x513 heighmap. I tested.
