Hi thanks. i don't need it, for now.
but this is something that an engine user can't(or very difficult to) get around if the situation is met, while at engine level it is easy(technically speaking) to do.
i wish JPCT engine can handle most situations (some problems can be solved by tricks without too much trouble) , but some features would require much effort from you, those are not what i would ask for , such as ortho camera.
if some features can be easily achieved from engine level, then having them would make JPCT engine better - less limitation, wider use.
i have a feeling that JPCT engine was designed and tested mostly for small scene, like indoor scene. while i mostly do open world scene. so i encounter (or fore-see) some situations that are difficult to solve, shadow bias is an example.
but i like JPCT most, and my main hobby project is made with JPCT (mostly physics simulation , with simple graphics)
