I don't see any big site on Cobra 3D !
Where is a feature pages ? (i doubt it will have as many as TV3D :
3D standard, great terrain and multitexturing, shadows ,shaders
with dynamic lights , physics etc ... all simple functions)
some 3D demos ?
Few lines of code like TV3D ?
Caus in Blitz3D asked too many lines compared to some others engines
And BLitz3D format is not old now ?
TV3D format can integrated lightmap , normal/specular maps etc ...
a link

?
I have in plan a 3D shoot them up : so TV3D or 3DGS will suit perfectly !
But people wanting big games need power, lod , perhaps some scene manager ,
etc ... TV3D can handle big games perhaps( i steel need to see a big complete outdoor game in Oblivion style , and doubt we will see one in indie area).
Cobra 3D is not very popular everywhere and lot younger than Ogre3D, TV3D and ome others , but if you have a link to the 3D part , features and some demos ?
Another big problem : write your own tools :
TV3D engine can run easily in windowed mode on a windows form :
you can add windows sliders buttons etc ... and place directly in their
events some code like :
moveObject(object1,100,100,0) ;
Cobra 3D like Blitz3D don't support that. so creating some special tools like
world editor, model editor/properties, RPG panels for editing characters
attributes etc ... won't be easy.
Blitz3D had some Gui made by some guys, but waiting a year or more to Cobra to come popular, free of bugs , some good GUI etc ...
Not for me.
