i think of another question:
is a Texture fully loaded from storage when Texture is constructed or when Texture is added to TextureManager? or it's not fully loaded from storage until it's requested for render?
i mean , when a Texture is constructed, it can be just a description of the image , but without loading the actual image texels.

the reason i want that is: my coordinate system is different from JPCT system, so an object loaded from 3DS has wrong orientation and wrong lighting.
a way to solve this is i switch vectors of the vertices.
or i have to find other ways.
ps: my coord system is forward-left-up.

can the game be downloaded somewhere else except from google server? i can't download the game.
although i am not an RPG gamer, i would love to see a complete game made with JPCT engine and by the author of JPCT engine

i found that the horizontal size of the shadow is correct, but the vertical size is smaller. the wall is smaller in vertical dimension, so it seems the receiver should be square or the shadow would be deformed. is that so?

i used Shadowhelper to cast an object onto a wall, and noticed that when light is far away, the shadow was smaller than the object. is it normal? shouldn't the shadow be at least as large as the caster?

yes, it's the beach that appears dark. but the beach is also from the png image, just the color is yellowish instead of white.
the beach and the white color part are both opaque part of the png image.

i have a transparent object with the same fog setting as other opaque objects, but when fog is dense ( close to farclip), the output color is not close to fog color. so the transparent object stands out when viewed far away.
 is there a problem with the blending method?
