Yeah, Quads are not supported yet. I still have to write some functions to convert it, should be pretty easy, i just haven't done it yet.
Thanks for the comments, i hope it will be useful to someone
Thanks for comments. About the suggestions, they are very welcome and i will put them on my todo list. Like i wrote on the wiki, there are going to be more pivot types, like for rotation and scale and that should make light positioning easier. Also, on the first version the camera used a pivot and rotated around it but i later changed that, i will come back with that feature on a check box
Your links are broken.
How large i am trying to make it? As good as a i can, but without killing myself in the process. This software is a one-man-only work and the only help i receive (and it 's a big help already) is from users telling me what they need next. I don't plan to expand the lighting system atm, mainly because i have tons of other things to work, but thanks for the suggestion. About the normals, i will make some option to flip channels, so any tool will be capable of generating normals for it.
